Kevel

APIs to build custom ad servers

Overview

Kevel provides API-based building blocks to help companies build their own ad servers, enabling features like sponsored listings and native ads within their platforms. Developers integrate Kevel’s APIs to handle ad serving, targeting, and delivery, and customers pay via subscription or usage, often launching a custom ad platform in weeks. Unlike fixed ad servers, Kevel focuses on flexible infrastructure that lets each business design its own ad experiences and revenue models with speed and control. The goal is to help companies monetize their platforms securely and at scale without starting from scratch.

Simplify's Take

What believers are saying

  • Dollar General and The Trade Desk launched unified onsite-offsite activation in May 2026.
  • John Lewis and Waitrose selected Kevel in June 2026 for onsite retail media.
  • Kevel's April 2026 Velocidi acquisition strengthened segmentation and personalization capabilities.

What critics are saying

  • The Trade Desk partnership with Dollar General compresses Kevel into interchangeable infrastructure.
  • Epsilon still controls John Lewis off-site media, limiting Kevel to onsite dependence.
  • If retail media standardizes on Shopify, Criteo, or Google, Kevel becomes niche infrastructure.

What makes Kevel unique

  • Kevel's API-first Retail Media Cloud powers custom ad servers across multi-brand retailers.
  • Kevel unifies ad serving, audience segmentation, and self-serve tools without outsourced media control.
  • Adobe Experience Platform integration on February 25, 2026 makes first-party data instantly actionable.

John Lewis Partnership teams with Kevel as it further strengthens its Retail Media offer.

John Lewis Partnership teams with Kevel as it further strengthens its Retail Media offer. The John Lewis Partnership has appointed Kevel to power its on-site retail media network, across both the John Lewis and Waitrose websites. It's the Partnerships' latest move to future-proof its retail media offer to brands, with its focus on providing highly personalised and useful content benefitting customers and brands alike. The Partnership attracts millions of customers every year across JohnLewis.com and Waitrose.com. 60% of John Lewis' orders now take place online, making it an increasingly popular tool for brand partnerships. Drawing on its AI-powered, API-first Retail Media Cloud, coupled with its experience supporting multi-brand retailers, Kevel has worked collaboratively with the John Lewis Partnership to develop a bespoke advertising platform that delivers advanced targeting. The first-party data allows brands to target customer segments that enable advertisers to reach the right shoppers at the right moment. It features easy self-service tools, enabling brand partners to go live with custom campaigns quicker than ever before, and supports native ads and sponsored listings across John Lewis and Waitrose websites. It also includes new 'ROPO' measurement capabilities; closed-loop reporting designed to reflect the 'research online, purchase offline' shopping habits of customers. For the first time, this allows brands to track whether their retail media has led to sales, even if the purchase is made in-store, by bringing in data like the use of a loyalty card. This helps close the long-standing gap in how brands measure the impact of onsite media on in-store sales. Kaitlin Craig, a digital retail media lead for the John Lewis Partnership said: "This is a huge step forward for our digital retail media offer. With over 160 years in retail, we hold really rich customer insights - and we're now able to share this with trusted partner brands." "By targeting our retail media, we can improve the experience for brands and customers alike - whether that's reminding customers of old favourites, or helping them connect with exciting new brands. The early results are exciting, and we're only getting started." James Avery, founder and CEO of Kevel, commented: "The John Lewis Partnership is exactly the kind of retailer Kevel was built for - a brand with deep customer loyalty, rich first-party data, and the ambition to own its media proposition rather than outsource it. We're proud to provide the infrastructure that gives them the control and flexibility to build a media network entirely on their own terms." The platform is being rolled out in phases, with display placements already live across John Lewis and Waitrose. Sponsored product ads will follow later this year. The Kevel partnership is the latest addition from the John Lewis Partnership as it looks to strengthen its retail media offer for its brands. Epsilon continues to oversee off-site advertising for John Lewis and Waitrose - including digital display and online video ads served across the open web and streaming services - whilst also offering first-party data and closed-loop measurement. In November, John Lewis also unveiled a seven metre-high digital billboard in the atrium of its Bluewater branch, to help bring cinematic above-the-line content to customers. The screen formed part of a series of high-impact touchpoints, with eight custom-crafted screens across the shop - which were quickly utilised by brands including Neff Appliances, Lego, Sony, and Samsung.

ADvendio and Kevel team up to streamline retail media operations with AI-powered automation.

ADvendio and Kevel team up to streamline retail media operations with AI-powered automation. As retail media networks continue to expand globally, retailers are facing growing operational complexity across campaign management, targeting, reporting, and billing systems. To address these challenges, ADvendio and Kevel announced a strategic partnership designed to simplify and scale retail media operations through AI-driven automation. The integration combines ADvendio's retail media Revenue OS with Kevel's API-first retail media infrastructure, allowing retailers to centralize campaign workflows and optimize omnichannel advertising operations within a unified platform. The partnership also introduces AI-powered agents aimed at improving operational efficiency and accelerating ad sales across retail media networks. According to the companies, the collaboration enables retailers to automate critical workflows such as trafficking, forecasting, targeting, reporting, and billing while maintaining full ownership of their data and infrastructure. "Integrating Kevel's high-performance ad infrastructure into the ADvendio ecosystem is a game-changer for retailers looking to move beyond manual campaign management," said Liga Bandere. "By combining our Agentic Revenue OS with Kevel's API-first technology, we're giving retail media networks the ability to automate the entire lifecycle - from the first draft to final billing." Retail media has become one of the fastest-growing segments in digital advertising, prompting retailers to seek more flexible and scalable technology stacks. The partnership positions both companies to support retailers looking to expand advertising businesses beyond traditional onsite placements into more sophisticated omnichannel strategies. "Retail media is at an inflection point and the networks that win will be the ones that can move fast, stay flexible, and keep full control of their data and infrastructure," said James Avery. "Together, we're removing the friction that slows retail media growth." The Kevel integration will become available within the ADvendio platform as part of the company's Spring 2026 release.
