About
Leading provider of API-first ad serving infrastructure for custom ad platforms
Kevel (formerly Adzerk) is an infrastructure-as-a-service AdTech company that provides APIs and tools for building custom ad platforms. The company enables publishers, marketplaces, and retailers to create their own server-side ad serving solutions without building the infrastructure from scratch. Kevel's platform is designed for companies that want to maintain control over their advertising technology while monetizing their first-party data through native advertising experiences. Kevel positions itself as an alternative to traditional third-party ad networks by empowering companies to build their own ad businesses. Their API-first approach appeals to technical teams at e-commerce platforms, retail media networks, and content publishers who want customizable ad solutions. The company rebranded from Adzerk to Kevel in 2020 to better reflect its focus on providing the infrastructure layer for ad platforms rather than being an ad network itself.
