Adzerk

Leading API-first ad server infrastructure provider for custom advertising platforms

Adzerk, which rebranded to Kevel in 2020, is an API-first infrastructure platform that enables companies to build custom ad servers and promotional platforms. The company provides developer-focused tools and APIs that allow businesses to create their own server-side ad serving infrastructure without building from scratch. This approach gives companies full control over their advertising experiences while maintaining user privacy and avoiding reliance on third-party ad networks. Kevel's platform is particularly significant in the AdTech ecosystem as it enables what the company calls 'Retail Media' and 'User-First Advertising' - allowing publishers, marketplaces, and e-commerce platforms to monetize their first-party data through native advertising experiences. The company serves mid-market to enterprise clients who want to build custom ad platforms that integrate seamlessly into their existing products, including major retailers, marketplaces, and content platforms. Kevel's infrastructure approach positions it as an alternative to both traditional ad servers and third-party ad networks, giving companies the flexibility to create privacy-compliant, brand-safe advertising solutions.
