Betaworks is a New York City-based startup studio and seed-stage venture capital firm founded in 2007 by John Borthwick. The firm specializes in building and investing in network-focused media businesses, operating with a hybrid model that combines elements of both a venture capital firm and a startup incubator. This approach has led to the creation and support of several notable companies, including Chartbeat, Bitly, and SocialFlow.

Betaworks has also invested in high-profile startups such as Tumblr, Airbnb, Groupon, and Twitter. In 2016, the firm sold its product Instapaper to Pinterest.
