About

Xtreme Labs was founded in Toronto in November 2007 by Amar Varma and Sundeep Madra, and became one of the largest mobile development shops in Canada — building apps for big clients at a moment when most companies had no mobile capability of their own. Its alumni network is one of the more durable things it produced: Farhan Thawar ran engineering there and spoke at TechTO in September 2016 about hiring engineers, arguing that standard interviews predict performance poorly. Chamath Palihapitiya bought a majority stake in the business in September 2012, and San Mateo-based Pivotal acquired it in October 2013, in a deal BetaKit reported at $65 million cash. The sale had a long legal tail: an Ontario court later ruled against Varma, Madra and Palihapitiya in a suit brought by other Extreme Venture Partners shareholders over the handling of the sale and a Tinder stake, and the appeal was lost.

Backers

Chamath Palihapitiya personally bought a majority stake in September 2012; Extreme Venture Partners was an early shareholder. Pivotal acquired the company in October 2013.
