Google Apps API Startups

Full Contact, founded by Bart Lorang in 2010, started as Rainmaker—a tool to enrich Google contacts with social network data. After pivoting through multiple product ideas and receiving guidance from Techstars' David Cohen to focus on a single core mission, the company rebranded around its API that turns partial contact records into complete unified profiles. The company grew to seven figures in MRR through content marketing (viral blog posts), direct sales to founders and product managers, and eventually raised over $55 million in funding.
