Speaker BI am Anne Mazinga.
Speaker BI'm one of the co hosts for.
Speaker CYour today's interview and I'm Chris Walton.
Speaker BAnd I, and we, Chris have interviewed so many people in our years of doing this show, but one of my favorite things that we get to do is when we get to have companies that get to come back on the show and catch us up on all that they've been up to.
Speaker BAnd that's exactly what we get to do today.
Speaker BSo please join us in welcoming Wiliot's Vice President of Solutions and Architecture, Nick Matthews.
Speaker BNick, welcome to omnitalk.
Speaker BWe're so excited to have you here and you have so much to catch us up on that we're going to have to break this into two shows.
Speaker BSo this is just part one of our catch up with Wiliot.
Speaker BWelcome.
Speaker BWe're so happy to have you.
Speaker AThank you, Ann.
Speaker AI really appreciate it.
Speaker AIt's really a pleasure to meet both you and Chris and being on the program, I actually remember the first time that Williot got featured and I remember thinking, I know I'm going to make it one day onto that show.
Speaker AAnd so pretty, pretty glad to be here today.
Speaker AThank you.
Speaker CThat's awesome.
Speaker CThat's awesome.
Speaker CWell, flat real get you everywhere, Nick.
Speaker CAnd, and you guys have some big news which we want to get to for sure.
Speaker CBut, but for maybe those of, for those listeners that are maybe new to Omni Talk or relatively new, it's been a while since we had Wiliot on the program.
Speaker CSo start off by reminding us of about what Wiliot does and, and what do you oversee in your role there?
Speaker AYeah, so I think Williot's generally known for being a company that produced a wireless energy harvesting tag that uses BLE or Bluetooth signals to basically Collect enough energy and then transmit.
Speaker AWe transmit data such as location, temperature, humidity, and we can use some of that to determine movement or other kind of contextual activities and operations.
Speaker ABut what I think that people don't fully understand or maybe what we didn't communicate I think well enough as a company is that we, we also integrate all data that systems are using already.
Speaker AAnd so that includes, for example, manual scanning that takes place or other point of sale activity, even signals from rfid.
Speaker AAnd we actually aggregate all customer signals into our platform in the Wiliot intelligence platform.
Speaker AAnd then we provide a more complete, unified view of their supply chain.
Speaker BAnd tell us a little bit about your specific role at Wiliot.
Speaker AYeah, so I'm very fortunate enough that I get to lead a lot of the solution strategy, the development of use cases that are helping our customers.
Speaker APrimarily I focus on the Fortune 5.
Speaker AWe are really trying to show them the power of ambient IoT.
Speaker AWalmart's been a very early and awesome partner through that and we've certainly been able to augment their AI systems and unlock new levels of visibility and automation for them.
Speaker BYes, well, I want to dive into that a little bit more.
Speaker BBig, big time headline.
Speaker BThis we just covered on our show actually just a couple of weeks ago.
Speaker BGreg Cathy, who heads up this department for Walmart, he's been on the show before, he said in the press release for this announcement that Williot's allowing Walmart to do things that they couldn't do before.
Speaker BSo what are those things in your mind, Nick?
Speaker AGreg immediately saw the gaps in the current Walmart systems.
Speaker AWe always think that all of these big companies have all the data that they, that they really want, but we actually find out that's very much not the case.
Speaker AThere's data that they wish they knew that happened from the past and there's data that they wish they had when it's happening in near real time.
Speaker AAnd Greg knew that the BLE technology with WilioT could get us those signals.
Speaker AAnd so right now we're using it to directly notify associates in stores.
Speaker AThey need to take actions to improve their, their pallet unloads to make sure that their pallets are in the condition that Walmart needs them to be.
Speaker AThey're using it to manage inventory accuracy within the store.
Speaker AWe have already seen a significant amount of food waste reduction which has been outstanding.
Speaker AAnd really next year, in 2026, Walmart's already projecting to save tens of millions of pounds of food because of the Wiliot signals that are going to help them immediately take action.
Speaker ATo keep food where it needs to be.
Speaker BThat's great.
Speaker AAt the end of the day, Walmart has this motto about, they talk a lot about helping people save more and live better.
Speaker AAnd that's, that's 100% true.
Speaker AI, I've seen it as part of their culture and I, I really think that on top of all the really awesome stuff, ultimately there is going to be some increased sales at Walmart.
Speaker CYeah, Walmart's got their eye on the ball, without a doubt, Nick.
Speaker CSo I want to put this, I want to put the Walmart, you know, news in more context, though.
Speaker CSo, you know, recently, to set the table for everyone listening.
Speaker CLike, you had been deployed at Walmart in 500 locations.
Speaker CAnd, and just I think a couple weeks ago they announced that they're gonna, they're taking you to 4,600 stores plus, you know, roughly 40 plus distribution centers as well.
Speaker CCan you walk us through what this actually looks like in practice?
Speaker CLike, so from a deployment perspective, I'm curious, like, how are these BLE pixels placed on products?
Speaker CHow do they actually get read?
Speaker CWhat infrastructure did Walmart need to make this happen?
Speaker COr, you know, what did they already have in place?
Speaker CCan you go through all that in detail?
Speaker CBecause I'm really curious about it.
Speaker ASo when you talk about the 4600 locations, I want to make sure that everybody understands that that is all the Walmarts.
Speaker AYeah, pretty much.
Speaker CYeah, it is, yeah.
Speaker ACoast to coast, that's, that's the United States.
Speaker AAnd we're really, we're really flattered by that vote of confidence from Walmart.
Speaker AAnd those 40 distribution centers are going to manage all of their grocery pallets.
Speaker ASo you're talking about hundreds of millions of units moving around across the country.
Speaker AAnd that all really started in Texas.
Speaker AThere's a very, very large effort by Walmart to integrate new technologies.
Speaker AAnd they do a lot of their deployments and their testing in that Texas metro.
Speaker AAnd so we did, we focused on deploying in sites across really three states, Texas, some in Arkansas as well as in Louisiana.
Speaker AWe got up to a couple of hundred locations.
Speaker AAnd what we did was we looked for opportunities where the data could easily be associated to the tag.
Speaker AAnd so, you know, nobody is just applying a new sticker on all these pallets.
Speaker AThat's not what's happening at all.
Speaker AWe actually look at where Walmart is already applying a label and we look at the system they're using to apply that and we just integrate into the existing label.
Speaker AReally?
Speaker AYeah.
Speaker ASo their 4x6 label is now a Smart label, it's got Wiliot Bluetooth sensor in it.
Speaker AIt's applied with the same automated technology that they're using to apply labels today.
Speaker AIn some cases, order pickers and distribution centers are using printers.
Speaker AThose printers were just simply replaced and retrofitted with a BLE enabled printer.
Speaker ASo when they queue up that label, the label that comes out, it associates to the order that they're filling and then goes on the pallet from there.
Speaker AWe follow it actually from the distribution center through the store and really through the end destination of the pallet.
Speaker CSo Nick, just to make sure.
Speaker CSo the pixel is getting placed at the pallet level, the carton level, the individual product level.
Speaker CWhich one?
Speaker ARight, yeah.
Speaker ASo right now we are at pallet level.
Speaker CPallet level.
Speaker COkay.
Speaker ANow what's really awesome though is of course we have been in development of other granular inventory solutions for Walmart, but that's really what we're going to be doing.
Speaker AExactly the same thing we just did here where we went to a couple of hundred sites this last year.
Speaker AWe'll be doing that this next year with some expanded use cases.
Speaker ASo I'm actually really looking forward to another national announcement next year.
Speaker ANow that's not a commitment by Walmart.
Speaker AI don't want to put them on the, on the, on, on blast there, but I'm just, I'm very, very hopeful that with the success that we've had at pallet level, with the excitement that we have from so many different VPs inside the organization, that we'll, we'll no doubt continue to see some more success there.
Speaker CYeah, that's at least the goal.
Speaker CRight.
Speaker CAnd with all the regulations around food safety at the pallet level, that's pretty important too.
Speaker CSo how are, how are the, how are the pixels actually red?
Speaker AOne of the cool parts about Bluetooth is of course that it is rather ubiquitous across the environment.
Speaker AThis is one of the big differences between Bluetooth and rfid.
Speaker ARFID is a great technology, but it's kind of like a hydrogen car.
Speaker AThey're super, super cool, but it's hard to find a hydrogen gas station.
Speaker ASo it's very similar with an RFID reader.
Speaker AThey're not everywhere, versus a Bluetooth reader, which is.
Speaker AAnd so we have added some architecture or some, excuse me, some infrastructure to the stores.
Speaker ASo very few.
Speaker AIt's basically just less than five to six devices typically for every store.
Speaker AAnd that enables us to really just use the printers at the distribution centers, the infrastructure at the store, and then all the associates, they have the ability to use their phones to receive alerts and actually take action.
Speaker BThis is so cool.
Speaker BNick, thank you for letting us dive in and ask all these questions because it's just so fascinating how it's working.
Speaker BAnd I think it's really important that you set the context for how this differentiates from rfid, which we're also hearing about in the space quite a bit these days.
Speaker BOne thing that you mentioned earlier though, is that this technology, now that it exists, is helping store operations.
Speaker BSo at the store level, associates are able to kind of see, see what's coming into their back of house.
Speaker BWill you talk a little bit more about how this data from the devices is kind of converging into actionable items on a Walmart associates to do list?
Speaker AYeah.
Speaker ASo IoT pixels or Bluetooth pixels, they're continuously streaming data.
Speaker ASo as long as there's that level of RF in the environment, they're going to continue to harvest energy and transmit.
Speaker AAnd when they're giving you that constant signal of temperature, you can reference a lot about movement, you can reference about condition.
Speaker ACertainly with every transmission you have an impression of location.
Speaker AAnd so all of that goes directly into Walmart's AI systems.
Speaker AAnd then what the associates are doing is they're receiving alerts.
Speaker AMobile notifications we started out with, I mean we can do emails, we can do text messages, we can do alerts through apps, we're using native systems to Walmart.
Speaker ASo one of the biggest things here is we don't require the associate to do anything additional.
Speaker AThey just enable a site and now they're getting all this information.
Speaker ARight.
Speaker ASo in from an associate standpoint or somebody that's working in the store on the ground, it's completely transparent.
Speaker AThey don't even care that it's there.
Speaker AThey just know, hey, now I know that I've got a problem that I can go address or I know that I can go do something before I have a problem.
Speaker ASo we're giving them that continuous real time visibility, you know, that enhances Walmart's ability to anticipate, respond and really optimize their operations right there in the moment.
Speaker ASo I think in the future, you know, the ambient IoT data integration with AI that's just going to continue to kind of grasp more and more use cases to enhance the supply chain performance.
Speaker CSo Nick, what's an example of that?
Speaker CSo say I'm a Sam and a Walmart store associate, what's an example of that?
Speaker CThat I can do my job in a better way than I could prior to Wiliot being In the store.
Speaker AYeah.
Speaker ASo let's just say for an example that you receive a truck and you've got a set number of pallets, you're supposed to pull off that truck, but it's got multiple deliveries it's going to make.
Speaker AOne of the things that we can do now is you can unload that truck.
Speaker AThat truck.
Speaker ABut if you have to pull off a pallet that wasn't supposed to go to your store, but you had to do it to get to another pallet.
Speaker ARight.
Speaker ASo now it's in the store where it shouldn't be, and you get the pallet that you were supposed to get.
Speaker AWe can actually send you a reminder if we determine that, hey, you guys, don't forget to put this pallet back on the truck.
Speaker AAnd that's huge.
Speaker ARight.
Speaker ABecause there's an incredible amount of cost with these pallets.
Speaker AYou know, they're very valuable.
Speaker AAnd when you do that just a few times in a year, you can imagine there's significant inventory discrepancies.
Speaker ASo we're fixing that.
Speaker AYou know, we're preventing that problem from even happening.
Speaker AIf you were to take a cold pallet and let's say you're.
Speaker AYou're unloading multiple cold pallets, you're moving one, but you forget to move another, and we can say, hey, don't forget to put that cold pallet back in the freezer.
Speaker AAnd because we don't want it to, you know, go out of cold chain compliance, William is really being leveraged to keep problems from happening, not.
Speaker ANot, you know, document that a problem happened.
Speaker CRight, right.
Speaker CAnd then you have a system of record that the items have been in compliance, too, throughout the process as well.
Speaker AUp until that is correct.
Speaker AAnd it does attract.
Speaker AYeah, it does.
Speaker AAnd that does lend itself to the.
Speaker ATo the fisma aspect of Wiliot's potential.
Speaker CYeah.
Speaker CAnd in addition to Nick, like the AP aspects of what you're talking about, too, there's a lot of products you want to know where those pallet, you know, I think, like, high value electronics, things like that.
Speaker CLike, I want to know that those are still on my truck at the end of the day and not, you know, winding up somewhere else.
Speaker CAll right, so, you know, we've touched on it a little bit in terms of, you know, you mentioned Greg, Cathy before.
Speaker CHe's kind of the executive sponsor of Walmart.
Speaker CWe've had him on the show.
Speaker CYou know, it's one of the hardest problems in retail is, of course, just knowing where your product is.
Speaker CBut in addition to that, what other roi, you know, can retailers expect from deploying a solution like Wiliot if they make an investment like this?
Speaker AI think, Chris, you know, when thinking about the retail market in general, the benefits are, they're so vast.
Speaker AYou know, you've got your inventory accuracy will yachts helping resolve inventory discrepancies through this, this continuous pallet level visibility and really automating a lot of alerts that previously didn't exist.
Speaker AWe are very, very committed to freshness and waste reduction.
Speaker ASo real time location, temperature sensing, we're protecting perishable goods and reducing spoilage.
Speaker AThen you've got labor efficiency, automation.
Speaker AYou know, it's eliminating a lot of manual scanning that is a huge benefit to any company.
Speaker ARight.
Speaker AIt really frees the employees to focus on customers.
Speaker AAnd Walmart is absolutely committed to customers.
Speaker AThen you've got your compliance, the Food Safety Modernization act or FISMA.
Speaker CRight.
Speaker AThat ambient IoT data provides a verifiable proof of delivery, handling, cold chain integrity.
Speaker AIt really helps strengthen supplier relationships and ultimately virtually all of our customers.
Speaker AWhen we are landing the right use cases, you know, we see improved sales.
Speaker ARight.
Speaker ASo we're improving the customer shopping experience.
Speaker ARight.
Speaker AAs I mentioned, right.
Speaker AWalmart is very committed to the customer and they're looking at this from how are they making the, the customer journey easier and still helping the customer, you know, live better and save more?
Speaker BNick, you know, on this show we say often, like, if Walmart's doing it, other retailers are likely going to be paying attention.
Speaker BAnd obviously this partnership that Williot created with Walmart is a ringing endorsement of the product.
Speaker BBut what has to be true at a retailer and those listening in our audience for Wiliot to work successfully, like, are there any things that you would caution listeners or you would say, you know, this is the right investment for you?
Speaker BIf X, Y and Z is true.
Speaker AThat'S a, that's a really great question.
Speaker AI guess the way that I internalize it though is I'm kind of thinking about what are the things that I've seen go wrong with retailers to take a look at it.
Speaker ARight.
Speaker AAnd I think one of the biggest things is they try to do too much with it too fast.
Speaker AI think the first thing that you need to do is say, I've got this problem, let's go see if we can solve it.
Speaker AOnce you solve that one problem and you said, okay, through that process, you integrate into all of your ERP systems your entire tech stack.
Speaker AYou get the right security permissions, suddenly all the other use cases that you want to use the technology for they become very easy and fast to execute.
Speaker AAnd I think that any retailer who is moving goods that they actually want to know where they are at can use our technology again.
Speaker ARight.
Speaker ABluetooth is in fact everywhere.
Speaker AI don't know what the world's current phone saturation rate.
Speaker AYou know, everybody has a smart smartphone these days, but because of that, the ease of adoption only, only continues to get easier.
Speaker CRight.
Speaker AThe cost of edge devices that we do use to augment some of that RF in the environment that those prices continue to go down.
Speaker AAs you mentioned, Walmart is a real leader in the retail thought space and I think we're going to be seeing some additional announcements soon as additional folks are saying, hey, there's something here.
Speaker AAnd our goal with Wiliot, right, our North Star has always been a truly ambient IoT experience that tracks something end to end.
Speaker ARight.
Speaker AFarm to fork is something we used to say, but this idea of absolute compliance and ability to make sure that customers are getting the highest quality with the highest confidence that it's been within those safety conditions that we expect for food, for example, Right.
Speaker AEven if it's material that we want to make sure, you know, we're not getting a fake Apple Phone whatnot.
Speaker ARight.
Speaker AWe're getting a real Apple Phone, that sort of thing.
Speaker ASo, you know, anybody who wants to actually monitor their inventory, anybody that wants.
Speaker CTo.
Speaker AMake sure that their goods are in temperature compliance, that they are making sure that it is the highest quality, can, can certainly receive a ROI from, from Williot.
Speaker BNick, I'm what I was just going to ask you to go into that a little bit deeper so it doesn't have to be a Walmart size operation like this could be for a smaller regional grocery chain that's sourcing locally that, you know, may or may not have more than one distribution center or something like, is it still a viable option for them to be considering right now or would you recommend that they wait until they've got more of like a infrastructure system set up so that they can tack more onto this before it really kind of starts to show its value?
Speaker AYeah, absolutely.
Speaker AI think that the size of the operation doesn't matter as much as the commitment to quality and the commitment to excellence.
Speaker AThe truth is, is that we are working with some very small suppliers that are just kicking out, you know, a few tens of thousands of products or even less.
Speaker AAnd we're making sure though, that as they build their operation, they're doing it with, with those cost saving benefits.
Speaker ARight.
Speaker ASo we're actually helping them scale faster by making sure.
Speaker AThey lose less material or that they're getting that material in the, in the, in the right quality that it should be to their customers.
Speaker CYeah, that's interesting too, Nick, because when I think about like the fact that there's a lot of new legislation coming too, that also tends to force a commitment to excellence that maybe was not there before across the industry in total as well.
Speaker CSo that's, that's a nice thing to think about in regard to what you just said.
Speaker CAnd so Nick, let's get you out of here on this.
Speaker CYou know, Ann said it at the outset that, you know, know we're going to have, you have folks from Wiliot on a couple times with us because there's just so much to cover on this topic.
Speaker CAnd one thing that's particularly caught An's and Maya's attention is this concept of what your CEO calls physical AI, which is he thinks the next evolution beyond digital AI.
Speaker CThat's a pretty bold vision when you get right down to it.
Speaker CSo what does he actually mean when he says physical AI?
Speaker CWhat does that mean in practical terms?
Speaker AWilliam's been really good at putting the t back in IoT or the Internet of things.
Speaker AWe put the thing back in it.
Speaker ASo what we're really trying to do is extend artificial intelligence from the digital world of clicks and searches and really put it into the physical world around us.
Speaker AWe're trying to bring intelligence to objects, products, into the environment and help move our economy.
Speaker ARight.
Speaker AWe want to create a seamless connection between data and the real world.
Speaker ASo physical AI really, it connects the billions of everyday things pallets produce, medicine, manufacturing equipment, all of that to really deliver a continuous stream of real time information.
Speaker AThis live data layer, it powers AI systems and it gives them that understanding of what's happening across the physical world.
Speaker AAnd really it becomes an extraordinary fidelity.
Speaker AYou know, with, with that power AI can really operate with, with true precision.
Speaker AIt, we're making, you know, instant adjustments to decisions on supply chain routes.
Speaker AWe're looking at, you know, the temperature changes in near real time.
Speaker AWe're looking at expected journey compliance and patterns where if that journey is shifting, we now know the, the third and fourth order effects of that.
Speaker ARight?
Speaker ASo we're, we're driving improvements to freshness, we're driving improvements in efficiency, even safety.
Speaker AAnd I hope that your listeners tune in because physical AI is, it's already here, right?
Speaker AWe're operating at a massive scale.
Speaker AWalmart's nationwide deployment with Wiliot is really demonstrating just how combining ambient IoT and AIT is transforming.
Speaker AExcuse me.
Speaker AAnd AI is transforming the physical world.
Speaker AIt's becoming an intelligent, responsive network that is, is providing benefits to businesses, associates, consumers.
Speaker ARight.
Speaker AAnd I, I believe it's Jerome you're going to be speaking with for that bulb.
Speaker AAnd what a genius he is.
Speaker ASo.
Speaker AThat guy is doing amazing things.
Speaker ASo I can't wait to, to listen to that episode.
Speaker CYeah, it sounds really cool.
Speaker CI can't wait either.
Speaker CI mean, you just got me thinking about this, like, as this evolves, like.
Speaker CRight, yeah.
Speaker CYou can start to get a sense of where things are moving in the physical space without cameras.
Speaker CAnd like, I just start thinking about even the application of this in the store.
Speaker CLike, product comes in off the truck, what's the best path optimally to get that product back on shelf or back in the warehouse?
Speaker CWe don't really know the answer to those types of questions right now because we can't study them and document how they actually exist in the world today.
Speaker CSo, yeah, that's going to be a really fascinating topic.
Speaker ATotally agree, Chris.
Speaker BWell, Nick, thank you so much for sharing all of your expertise in your years of working with Wiliot and for bringing us all up to speed on everything that you've been working on.
Speaker BYou have been busy, and I can't wait to dive into the physical AI conversation in our next session that will be coming out in December.
Speaker BSo those of you listening, stay tuned.
Speaker BThat will come out right before the holiday break.
Speaker BBut, Nick, if people have questions before then, they were intrigued by this conversation.
Speaker BThey want to ask you more questions about how you did the Walmart deployment.
Speaker BWhat's the best way for them to get in touch with you to learn more about Wiliot?
Speaker AYeah, thanks.
Speaker ASo you can get me at LinkedIn.
Speaker AReally, I'm pretty active there.
Speaker ABut you can also email me directly at my work nick.matthewsilliott.com all right, that.
Speaker CWraps us up today.
Speaker CThanks to Nick Matthews of Wiliot for educating us on all things Bluetooth tracking in store and also talking about his deployment at Walmart.
Speaker CAnd thanks, everyone, for listening in.
Speaker CToday's podcast was produced by Ella Searior.
Speaker CAs always, on behalf of all of us here at Omnitalk, be careful out there.
