Retail Media Breakfast Club

Instacart’s advertising business is officially in its third act, and it’s the most ambitious one yet. In this recap of my recent article for The Drum, I break down how Ali Miller, GM of Ads at Instacart, is thinking about the company’s evolution from sponsored products to something much bigger: becoming the infrastructure that powers an entire retail media ecosystem.

I walk through Instacart’s three-act playbook, why its early bets on incrementality and self-serve set it apart, and how platforms like Carrot Ads are quietly reshaping how brands and retailers think about scale, measurement, and simplicity. If you’re feeling the weight of a fragmented retail media landscape, this episode offers a clear lens into where things are heading, and why Instacart may be further ahead than many realize.

Instacart Ads GM Ali Miller On The Company's 3rd Act of Advertising
===

[00:00:00] Kiri Masters: Allie Miller thinks about Instacart's advertising evolution like a three Act play. Act One was fundamentals, act two was expanding formats and objectives. Act three, the one Instacart is in now, [00:00:15] is about becoming infrastructure for an entire ecosystem. Allie Miller was promoted to general manager of advertising at Instacart in July of last year, but she has been architecting this trajectory [00:00:30] for over four years.

[00:00:31] Before Instacart, she spent more than a decade at Google leading the full stack redesign of Google Ads, which was then AdWords before moving to YouTube where she directed product for the ads advertiser experience. [00:00:45] And at YouTube she established goal-based buying across awareness, consideration, and action

[00:00:51] scaling offerings like TrueView for reach and introducing small and medium business friendly creation tools. And that [00:01:00] ad tech pedigree matters because instacart has been first to market repeatedly, self-serve ad platforms, incrementality, measurement, powering other retailers ad networks.

[00:01:13] Now competitors are [00:01:15] studying what Instacart built and replicating it with bigger budgets. So Allie Miller faces the classic innovator's dilemma. How do you stay ahead when your playbook becomes industry standard?

[00:01:27] Today I'm sharing an article that was [00:01:30] originally published, my column at the drum

[00:01:32] on December 15. Let's go.

[00:01:34]

[00:01:36] Kiri Masters: Acts one and two, building the foundation. When Allie Miller joined Instacart in 2021, the company was coming off the pandemic with massive [00:01:45] attention from users, brands, and retailers. The natural starting point had been sponsored products, the basic unit of retail media advertising. But even there, Instacart differentiated early.

[00:01:56] Here's what Ally told me. One of the first areas where we tried to [00:02:00] differentiate ourselves from other retail media networks is not just looking at attributed sales, but really looking at causal random control and exposed groups to understand the total incrementality of Instacart sponsored products.

[00:02:13] That was 2021 when [00:02:15] most retail media networks were still pitching brands on basic attribution. Instacart was already proving incremental lift. With proper test design, the platform was also self-serve from day one. That was unusual at a time when most [00:02:30] retailers started out with direct sales and insertion orders before eventually building out self-serve capabilities.

[00:02:38] Act two of Instacart ads brought display and video formats marrying what Allie calls [00:02:45] inspiration. With Shopability, the company shifted to marketing objective based buying, allowing brands to optimize explicitly towards goals like driving new to brand sales or total sales, rather than just managing individual [00:03:00] cost per click Bids.

[00:03:01] Now for Act three, the ecosystem play. When Instacart launched Carrot Ads in March, 2022, which is its platform that powers retail media networks. For other [00:03:15] e-commerce sites, it was years before other retailers announced similar platform ambitions.

[00:03:21] Now Ali is doubling down on the company's third act, revolving around becoming the infrastructure that other commerce players can plug into. Cara Ads [00:03:30] now powers retail media networks on 240 plus e-commerce sites, including Thrive Market, Hy-Vee, and Uber Eats grocery experience.

[00:03:41] This platform strategy is suddenly everywhere. [00:03:45] Amazon announced its retail ad service earlier last year, signing partnerships with several retailers, including Macy's Best Buys. Lisa Valentino recently outlined a vision of Best Buy as an open platform for data collaboration and audience extension, [00:04:00] but Instacart has been executing this model for longer.

[00:04:04] The pitch to brands is straightforward. Buy once, activate everywhere. Log into Instacart ads, launch a campaign, and it serves across the Instacart marketplace. [00:04:15] Plus those 240 Cara ads websites for emerging brands with limited distribution ads extend automatically as soon as their products hit shelves in new locations, and for large brands managing dozens of retail relationships.

[00:04:28] it's a consolidated buying [00:04:30] experience with consistent measurement. And Ali says this helps small brands with limited distribution get all of that opportunity they possibly can. And for large brands, it's much easier to have a single place to buy and measure and have consistent measurement. And boy [00:04:45] do I hear that request all the time. Miracle Ads is the Ad Tech solution trusted by Rakuten and over 50 global [00:05:00] enterprise retailers. That's because Miracle Ads was built with both three P Marketplace sellers and one P suppliers in mind. Both advertiser audiences demand a seamless advertising journey from onboarding to [00:05:15] reporting.

[00:05:26]

[00:05:28] Kiri Masters: So what about the pitch to [00:05:30] retailers? Well, the pitch is that it's not just a plug and play ad server, but the opportunity for retailers to tap into Instacart's National Advertiser Demand. This is a significant benefit for retailers looking to grow their ad revenue after the initial [00:05:45] easy money of ad spend.

[00:05:46] Migrating from trade and shopper marketing funds is exhausted. Another thing that we talk about on this show all the time is. Tapping into new advertiser demand.

[00:05:58] Now in the full article, I [00:06:00] also talk about a couple of other topics related to Instacart, which is black box algorithms and how a lot of advertising platforms are sort of moving towards black box algorithms. Whether.

[00:06:13] Advertisers like that or not. [00:06:15] So I got Ali's comments on that. And then also the in-store retail media hedge that Instacart is also really investing in with their caper carts. Um, I first got a [00:06:30] experience of cap carts in real life at NRF, and it was, it was really cool. I can't wait to see more of them out there in real life.

[00:06:39] And as I have shared. On the podcast before, I really do think that these in-store [00:06:45] capabilities are a huge hedge, for retail media networks looking to bolster their offering as we see more purchases happen, through AI agents or even just start with [00:07:00] ai.

[00:07:01] Conversations, which reduces the total amount of sponsored product ads that get served, which is currently the meat and potatoes of retail media. So I do recommend checking out the full article if you wanna get those POVs, [00:07:15] but just wrapping up here, the broader retail media landscape is fragmenting under its own weight.

[00:07:21] More than 200 retail media networks now compete for advertiser attention. While brands struggle to manage relationships with an average of five to seven platforms, [00:07:30] growth is decelerating, 15.6% in 2025 versus. 25.1% in 2024 according to the IAB. So Instacart's Ali Miller believes [00:07:45] simplification is the answer here, but not the kind that removes advertiser control.

[00:07:49] She's building for a future where brands can buy in one place and activate across an entire ecosystem, but where they maintain transparency into results and choice in how their [00:08:00] campaigns run. Unlike executives rushing toward full automation, Allie is doing this with Google Bread, discipline, test, measure, prove scale.

[00:08:11] ~She's layering new AI capabilities on proven.~

[00:08:11] ~Now, let's just remove that past little bit, starting with unlike executives.~

[00:08:11] ~And one of my favorite quotes from the conversation was, ~and one of my favorite quotes from the conversation with Allie, choice [00:08:15] and Trust are really key. We are not forcing this.

[00:08:18] Wrapping up here, I have been a big fan of Instacart ads from day one in 2020. I even wrote a book about Instacart ads called Instacart for CMOs with my co-author [00:08:30] Stefan Jev and. they have been truly first in a number of different ways with regard to advertising. And also they were the first, retailer, I guess, quote unquote, to roll out a, AI chat [00:08:45] assistant as well.

[00:08:45] So, so many firsts for Instacart. It is really interesting to think about where they will go next. And after speaking with Allie, I think she has, really clear vision for the future, and I'm excited to see where it goes.

[00:08:59] Thanks [00:09:00] for listening and I'll catch you next week.
