Kevel (previously Adzerk) is helping brands everywhere drive more online revenue through sponsored listings, internal promotions, native ads, and more. They do this by providing engineers and product managers the APIs needed to quickly build fully-customized ad servers. Their award-winning platform handles over three billion API requests each day, and it’s helped industry leaders like Yelp and Ticketmaster shorten their build times by more than 90%.

For far too long, everyone has been at the mercy of big ad tech. They force you to play their game, by their rules, while they compromise your users’ privacy and online experience. And until now, only the biggest companies have had the resources to take back control by building their own monetization platforms.

With teams in Durham, San Francisco, and London, Kevel is working every day to keep the Internet free by making it easier and more ethical for brands to monetize their corners of the web.
