Kevel (formerly Adzerk) builds a suite of infrastructure APIs that enable companies to create custom ad platforms for sponsored listings, native ads, internal promotions, and more across websites, apps, video, podcasts, and digital out-of-home screens.[1][2][5] It serves publishers, media companies, marketplaces, and retailers—such as Ticketmaster, Yelp, Strava, Klarna, WeTransfer, Bed Bath & Beyond, and United Airlines—who want to monetize their digital properties without relying on ad tech giants like Google, Amazon, and Facebook.[2][5] The platform solves the problem of inadequate third-party tools by providing fast, flexible server-side APIs for in-house ad products, driving new revenue through user-friendly, privacy-focused advertising.[1][3][5] Growth includes a 2020 rebrand from Adzerk, an $11M Series A from Fulcrum Equity and Commerce Ventures, and a 2025 acquisition of Nexta, an AI-driven ad platform.[1][3][5]
Kevel originated as Adzerk in 2010, founded by software engineer James Avery after he acquired a small ad network in 2007-2008 and identified a market gap for better ad management tech during his independent consultancy work designing websites for local businesses.[1][2][4] Starting with a JavaScript-based ad server, the company pivoted to server-side API ads as the internet's future, evolving into infrastructure tools for custom ad products; early traction came slowly with the first customer in 2010 and a seed round in 2011, but APIs became the key differentiator years later.[1][2][4] In December 2020, Adzerk rebranded to Kevel for a "blank slate" beyond ad network perceptions, coinciding with the $11M Series A to fuel API expansion.[2][3][5][7] A pivotal 2025 acquisition of Nexta, founded by Martin Jensen (now VP of Partnerships), added AI-driven omnichannel ad capabilities.[1]
Kevel rides the trend toward in-house ad tech sovereignty, as publishers seek control amid privacy regulations, cookie deprecation, and big tech monopolies squeezing margins.[1][3][5] Timing aligns with post-2020 shifts to API-driven, first-party data solutions, accelerated by AI integrations like the 2025 Nexta acquisition for omnichannel revenue.[1] Market forces favoring Kevel include rising demand for customizable, non-terrible ads in performance marketing, with clients spanning e-commerce, ticketing, and fitness apps proving scalability.[2][5] It influences the ecosystem by democratizing ad infrastructure, helping mid-to-large players like Yelp and Klarna build Amazon/Facebook-style platforms, fostering a less centralized internet.[3][5]
Kevel is poised for expansion through API enhancements, AI via Nexta, and deeper enterprise penetration, targeting more digital property owners amid ad market fragmentation.[1][2] Trends like privacy-first advertising, omnichannel growth, and open-source tooling will shape its path, potentially drawing further funding or acquisitions as in-house platforms proliferate.[1][3][5] Its influence may evolve from niche API provider to standard infrastructure for revenue diversification, solidifying the mission to reclaim the internet from giants—building on Adzerk's scrappy origins to a mature, high-impact player.[1][4]
