This episode is sponsored by basis, the leading intelligent operating system for autonomous advertising. Its enterprise AI solution transforms campaign briefs into strategies and media plans that integrate directly into omnichannel activation. Bonjour. We are on day three of Cannes. We are sweating it out. There is no one I would rather be sweating it out at Cannes, except the people here who are in front of the camera and the people behind the camera who I'm looking at right now. I'm with Lindy Johnson, our head of programming for our Pro Guio events and our CTV events. And I'm with Allison Schiff, our managing editor. We've been doing this four years together and going strong. Friends who sweat together.
C
What?
B
Oh, you two.
C
Four years. Me too.
B
Yes, and me too. I'm of course Sarah Sluice, editorial director of Ad Exchanger. And your voice? My voice carries normally from some thousand miles away. We have so much to share about Cannes, so many insights. I think it'll be useful for those of you who are in Cannes and those of you who are on the other side. And honestly, there's benefits to not being in 90 degree heat while doing business work.
A
No FOMO about that, I'm sure.
C
None whatsoever.
B
So I'm going to give everyone who's listening at home or watching a buzzword bingo tracker because I think some of the themes we're going to talk about are, are going to come up. So the buzzwords that we may or may not say on today's episode are. Authenticity.
A
Take a drink.
B
Measurement.
A
Another one.
B
Outcomes.
C
Proof.
B
Proof is the new outcomes. Holistic authentication. OpenAI workflow. And of course you are listening to an Ad Exchanger podcast, Containerization. So with that, let's get started.
A
Go to the Riviera and talk about containerization.
B
I mean that's, that's what they're doing on all the yachts. So, Lynn, I want to start. Let's start with something authentic. Let's talk about authenticity. It was the topic of your newsletter for those of us who are getting the daily briefings. So what does it mean to be authentic and can.
C
Yeah, so authenticity came up a lot for me in conversations the past couple of days and on sessions I moderated are just talking one on one to people. Like there's some a CMO I spoke to about, you know, brands reaching people and in sports moments like the New York Knicks final or something. Hell, yeah. Hell yeah. Go Knicks. Right. Or, you know, moments like that. Or the World Cup. Right, Moments like that. Yes. Brands are meeting them in those moments, but what about after the moments? Right, so the word came up. You have to be authentic. You have to really engage them. Right. Then it came up again. I was talking to someone else about how do brands, you know, win in the LLM game? If there is any winning. I don't know there's winning, but at least how do they have visibility in the LLMs? And again, authenticity. And again, authenticity came up. Right. And finally, one other place where I was talking on a panel about identity and lgd, LGBTQ plus. I don't know why I keep getting tongue tied with the Alphabet mafia.
B
There's a lot going on. Yeah, there's a lot. We're staying around us. Yes, it's all good. This is just what can is about.
C
Yes, but one of the other things about authenticity was that, like I. The data that we use for identity needs to be authentic and we need to use it in an authentic way.
A
Do you mean authentic like real people?
C
Yes. And not bots and not.
A
Sure.
C
Yes. So that, that so really. So in the newsletter, the thing I talked about most was like, how. And with all of this, you know, the. The AI is doing the brief. The AI is in the workflow, the how do we still stay human?
A
What about synthetic audiences, though? That comes up more and more where you're using a synthetic audience as a focus group or to learn real insights about your real audience, but you're not actually talking to them the same way that you used to.
B
You brought this fully back to Ad Exchanger, didn't you? I love it. Okay. Is that okay?
C
Yeah, yeah, it's fine.
B
Synthetic audiences meet authenticity. Thoughts?
C
I mean, synthetic audiences did come up and there's same panel I was talking about. And the idea was you still don't know how it really works with people. You might use the synthetic audience, but that doesn't mean it's going to work with real people.
A
Still got to check. Check with someone who has a heartbeat.
C
Yes.
A
Okay.
B
So authenticity in the age of AI is even more important. I feel like that's a really good segue to talk about. Your briefing with OpenAI. They talk to press. I think it's a really big deal that they're here and here so quickly. They were in some like out of the way place. Right. Which I think is testament to how last minute this is. Most people, like rebook their same spots like a year in advance. Tell us more I mean, it's not
A
that far away, but it was really hot here, guys. So I was so wetting when I got there. It was about a 15 minute walk, 20 minute walk from the main drag. It was a press briefing for around 20 some odd folks.
C
Folks.
A
And it was several OpenAI advertising focused executives. They're building a team, explaining all the stuff they've already put out there. There was no news broken. But the fact that they were here, which is your point, is significant enough, the fact that they were making their debut, that they think it's important to get in front of people at a festival focused completely on advertising. Their CRO said something very telling. I mean, she was very emphatic. She said, we are in the advertising business and might be paraphrasing, but she was planting a flag. They're all planting a flag. They keep entering new markets. They entered, I believe it was South Korea and Japan just this week. They're in the us they're in the uk, they're in Australia, New Zealand. It's still in beta, but it's moving super quickly. And one of their executives said something like when you talk about a baby, you talk about it in terms of how old it is. Like week wise, like, oh, my baby is 19 weeks, but at a certain point you start talking about it in months. So I think they're about to make that transition. They put out so much so fast. Yeah, I mean it's only like February when they really started going full bore and it's June and they're already in Cannes.
C
So a question I have, because I saw this come up on LinkedIn. Do you know if anyone who uses ChatGPT who actually has seen an ad? Have you ever heard of anyone who's seen an ad?
A
Yes, I have indeed. In the wild. Joanna Gerber, our associate editor, wrote a story about an unnamed source, someone she knows, who saw a job recruitment ad in the wild. And this person wasn't logged in. And so we ended up writing a story about it and we verified it with OpenAI. Are you doing this? Showing ads to non logged in users? And yes, they were. So those ads are out there.
C
Okay, all right.
B
And one thing I want to talk about that's come up a bit or has been observed by people that I've talked to at Can. Is this cross pollination of executives across different companies? David Dugan is at OpenAI. AI used to be at Meta. Samantha Jacobson just joined OpenAI. She was at the Trade Desk. I talked to TikTok, their lead executive used to be at Meta as well. And there's just this total cross pollination between all of the major platforms. I think Amazon Ads hired a lot of ad tech veterans over the past few years. That's a really huge change. I talked to someone who was a veteran of Meta as well. So there's definitely like a Meta mafia that's like spread out to all the different platforms. And you know, last night like 10pm Having some and delicious wine, someone was talking to me about like the App Nexus mafia that like there's just like multiple leaders across independent ad tech that all worked at App Nexus together, like often at the same time. And you can just like spout off all of these people. And I think when you have people that were all seated in the same place, it really affects how they're designing platforms. And I also think that it leads to more friendly relationships and more partnering with each other because they've like, you know, I don't know, had to have their coffee water cooler and not their coffee cooler. I, I have seen ice coffee cooler at Cairns. So I'm curious, have you guys noticed that at all?
A
Totally, yes. I mean all the ones that you mentioned and more. It, it makes sense too that there would be a lot of hiring from Meta because all of these companies are either launching advertising businesses or basically becoming advertising business. What is Meta? It's an advertising business. It's massive. And so there are a lot of people that want bigger roles or they want to build something new. I mean Dave Dugan was at Meta for something like 12 years. Long before it was even Meta, it was just Facebook. And now it's exciting to be able to build some brand new thing because
B
Meta so mature, so many people that spent a decade at Meta that are now across these different platforms and maybe they have a little reunions and hashtags.
C
I'm sure they do Yahoo too, right? There's so many people everywhere.
A
Look at every LinkedIn and you'll see a Yahoo commonality.
C
So I see a lot of old Aolers. Okay, yes.
A
Well, and also Yahoo and aol. The same things.
C
Yeah.
B
Also last night, same party, I met the, the people who bought AOL and they have a really interesting thing they're doing. Buying all these different ad tech assets. It's called bending spoons. They're buying Vimeo. You know, this is just what happens when you talk to the person behind you in the drink line. Right. You actually get into some really interesting conversations. So yeah, there's a lot better for sure. So Alison, I know like workflow was one of your buzzwords for me, it didn't really come up so much. So what are people talking about?
A
Workflow. Well, it started to crystallize for me kind of early. I asked someone for an example of something that they think will be a real use for AI within the next 12 months or something that's already happening. And that person, it was Liz Roche from Albertsons. She said, oh, workflow, it's really going to optimize workflows. And then that just primes me. And it came up in, I think, like 10 conversations that I had without me bringing it up. And then when I brought it up to people, a lot of them nodded their head and seemed to agree that, yes, it's not very sexy, but it's very important. I. I met one skeptic, but I'll put them to this side.
C
Yeah, workflow came up for me as well with aws. You know, they're using a bunch of agentic tools within their workflows, content workflows, advertising workflows. They're talking about how it's freeing up people to do more strategic things. Right. It also came up when people talking about campaign optimization. They were talking about, you know, using AI in workflows, but then also being concerned about weather bias, whereas it's ugly.
A
Nice to hear that they're concerned.
C
Yeah.
A
Because some people are just going straight ahead, full steam ahead. We are on a boat, so full steam ahead.
C
Full steam ahead. So, yeah, that's where I heard workflows as well.
A
Workflows are important because they're foundational. And unless you really think about the A to B to C, like the recipe, you might actually be spending more time on a task using AI because you're just trying to figure it out and it's kind of janky and you don't really have a map in front of you. And so if a workflow is. I just, I can't help being a buzzword bingo person myself. But if a workflow is optimized, then you're actually saving time, not just using AI.
B
Right. And I think there, it's interesting that we all have. I'm about to say my buzzword next, but I think it's interesting that we have different things because I know one thing in my reporting style is I like, bring up things that I heard in previous interviews into my next interview. But, like, mine is measurements. I'm like, oh, I'm hearing about measurements. You're a cross pollinator too. And I roas. And people are like, oh, yeah. And then they kind of add their own thing and it definitely snowballs and I think that can happen collectively. But I also think there's like multiple parallel paths of people collecting different buzzwords which I haven't talked that much about containerization yet, but I definitely had a few interviews that were like we could talk about containerization all day. I feel like I want to save all day. I want to talk about some of that. I feel like for a post can podcast because I think my brain might sputter if I try to explain it clearly. Yeah.
C
Because I don't know what you mean by containerization at all.
B
Ask a friend, phone a friend, ask them if containerization is right for them
C
because it sounds like something with code.
B
Yeah, it's definitely an ad tech topic that's taken over. So we'll expect more from that. I'm going to be doing more investigation
C
when I'm back at Will you perhaps write an explainer about it?
B
I think Adam Exchange will definitely be writing an explainer about conversation. Stay tuned. So I want to talk about measurement outcomes. I roas this is something that I heard a lot. I guess I've been thinking about measurement a lot coming into Cannes so it was something I wanted to ask people about. So there is definitely that bias there. And I was at one breakfast where a lot of content owners, a lot of people on the media side were talking about wanting to enable this outcam based buying but that it's quite challenging. And I think the incremental roas piece, as Paul from Goodway Group CEO was kind enough to tell me, is definitely very much a commerce story and IROAS is kind of like the key metric for anyone in the commerce media space. And then I think, you know, I was talking to Stagwell Group. They're like it's not about outcomes, it's about proof and like their word was approved. So I think that we're seeing everyone focused on measurement. But I think what the key says that guy. Yeah, we got the boat chiming in if you heard that. But I think what metric it is might vary by channel and I think how people are thinking about measurement really varies. Like so it's, it's similar but also different. Yeah, yeah.
C
I think what you just said we heard the CEO of Within say today, right. That whether you're in social, you're in ctv, you're in linear, whatever. Like MMM might work one place but performance works another place. And you know, increment incrementality works. Like you said, when commerce is at play, which I know Albertsons is really into.
A
I have a metric literally called iroas.
B
I think we wrote about it.
C
Yeah, yeah.
B
And I was talking to the equative president, Michael Lehman on Monday and he talked about the uncertainty that's going on right now in the space. We've got like, you know, gas prices all over the map, like, lots of things outside of the ad space that are really making people feel uncertain. And I think that that is partially informing why people want to go lean into measurement, because there is certainty in measurement. And I also think. I think within. If you do it right. Yes, if you do it right. Yeah. Accuracy being another word that came up for sure. Especially today. And I think that there's a lot of talk around CFOs putting more pressure on CMOs. In what language do CFOs speak but measurement. They love their numbers. So that's all about proof.
C
Proof again.
B
Yeah. So while like CMOs, like, they might like, stuff around, like, oh, actually Stagwell has a really, really interesting take on this. It's the. Their marketing cloud and they kind of can monitor things like the. Not only like, the volume of, you know, people talking about how it's hot. I can, for example, which everyone has, but also like the intensity, the emotional intensity of that. So I like, I like, love that. And then it's very qualitative. Right. So it's like, also, how do you turn that into something that a CFO could speak? Like, okay, what does it mean that people are saying this is hot, like, and there's emotional intensity. What does it say about how much, I don't know how many fans we're going to sell or how much Ice water?
A
What is ice water?
B
I haven't in a while. Iced coffee to hot coffee ratios in the town of Cannes.
C
Like that.
B
Yeah, we're spiraling for sure.
C
Yeah, it feels like. Yeah, it feels like the CMO is like the fuzzy warm stuff right in the cfo.
A
I think, depending on the company for sure. But it seems like CMOs are starting to think a little bit more. Not like CFOs, but they're thinking about what their CFO might want from them. And it's probably good for CMOs to think in that way for their longevity. I mean, if you can prove that what you're doing has some kind of impact, then you get to stay around longer.
B
CMOs have pretty short tenures and I think being in. Can you see the value of the skill of translation? So I think that's what CMOs need to do with their CFOs. They need to translate what matters to them and how. Yes. And how they're seeing their marketing be effective with their audience and translate it into a way that the CFO can understand. And certainly when people are talking to me in ad tech jargon and maybe I've, you know, I'm like my nth meeting of the day. Like the more effective of a translator you can be for your audience, the more you can accomplish what you want. So that's just maybe that's maybe more of our. One of our light, soft, fun tips.
A
Hey guys, what's the. I'm just gonna totally change the topic. I think we're winding down. What's the most like unhinged thing you've seen on the closet this week? Something just weird that I've seen.
B
Oh my gosh, there are so many on the Quazette though. Cuz I've seen some things off the.
C
Off the.
B
Tell you.
C
Yes, yes, for suret.
A
To me, just as representative of the whole thing. Off the quette is fine. I. I'll allow it.
B
Hi. You go first cuz you had a good one. You were talking to me on the phone and then you're like also. Hold on. Sarah.
A
Oh, right. Yeah. I was standing in front of Meta beach waiting to go to their party concert thing early evening and these two guys walk by and they're wearing these big weather gloves because they're falconers and they had actual falcons on, on their arm. And they just walked right past and went in the direction of the Majestic. I'm like, okay, that's crazy. And then when I went inside, I mentioned it to somebody and they said, yeah, they hire those people, the Majestic Hotel does, because they have a seagull problem. And so they're there usually working the beach, trying to keep the seagull population in control. And my first thought was, well, old technology can sometimes just get the job done. You need literal falcons.
B
Yeah, actually my town is doing that too. It's also considered a humane way of pigeon control. So I think that to me that speaks to some of the logistics that you hear about where people are like this is a million dollar build. Or I was asking a PR people, PR person, like how they pay talents and like what it costs to fly people out. And so I think some of that is like really unhinged that people are spending probably collectively tens of millions of dollars to build things that are going to go away in a week.
A
And if the structures that are built on the beach are so solid, I mean full on stages and they have walls you can lean on. They're legit. And buy what? They basically don't exist on the Friday before. They're still working on them on the Sunday. By Monday, they're solid. By the following Friday, they've taken them down.
C
Right.
A
It's crazy, right?
C
When. When I first went to Amazon. I know it's a port, but I was like, oh, this is a hamlet, but I know it's a port.
A
They built it up like a little city. They have greenery and they have a library, by the way. Guys, they're giving away candles. Yes, Nell. Quote unquote, like, different shows. I got a candle that smells like Reacher. It kind of smells lemony.
C
I didn't know Reacher is lemon.
B
Yeah. Allison got a celeb selfie. I saw Hoda walking down the closet.
C
I saw Doc Rivers. I don't know if you guys know who that is. Yes. And we locked eyes where he gave me the nod, like, musician, right? No, he's a basketball coach.
A
Oh, my God. I did know that. Oh, I should have known that.
C
And we locked eyes and he gave me the. I know you know. Know who I am. What team?
A
What team?
C
He was Nick's at one point, wasn't he?
B
Yeah, I saw. You know, I saw a woman walking in six inch heels. That might be the most unhinged thing. I was like. I was like, she's definitely an influencer. Like, she's not. She's not here with her badge. She's here to be on stage. So that was pretty unhinged. Yeah.
C
Someone was telling us someone was following
B
her with a camera as well. So that was the second tell. Yeah.
C
Someone told us they saw Eva Longoria today and that the look she gave him was like, I am rich. I am above you.
B
Okay, well, you know, I did. I will end on this, then. Lovely note around my combo with the PR pro who's worked with a lot of talent, who said it's the A listers that are always really good and kind and professional. It's the same listers you have to worry about. And, yeah, so I'm like, this is actually a really good tip. Act like an A lister. Be kind to everyone, be professional, and, you know, be. Be a translator as we talk about marketing and outcomes. And be authentic. Hopefully you're authentically nice and not authentically the opposite of that. You gotta be nice and nice. Thank you for joining us on the at Exchanger can podcast. I hope that you learned something, whether you were there and you're consuming this on your flight home or you were back in the States or elsewhere. We appreciate you tuning in.
A
And Doc Rivers, if you're listening, I'm sorry. I know who you are.

In this episode, the AdExchanger editorial team reports from the Cannes Lions festival, diving into the central theme of "authenticity in the age of AI" in digital marketing. They examine the festival's hottest topics—authenticity, measurement, outcomes, AI workflows—and share candid behind-the-scenes stories and observations from the Croisette.
The team keeps their tone conversational, energetic, and occasionally irreverent. They demonstrate the overwhelming flood of buzzwords, the search for meaning and value amid rapid technological change, and the enduring importance of genuine connections—even at the world’s glitziest ad festival.
Ultimate lesson:
Be authentic, measure what matters, stay strategic about AI, and don’t forget your sense of humor (or your iced coffee) at Cannes.
