The Mobile Majority, a mobile advertising and attribution company founded in 2012 by Rob Emerich, has raised about $25 million and grew to roughly 100 employees. It earns a revenue share on ad spend run through its platform, and it reported over 10,000 end advertisers, from large brands like Ford to small local businesses. Emerich said the company was acquiring Qualcomm spinout Gimbal, and would rebrand under the Gimbal name.

Foursquare transformed from a hot consumer social network (valued at $650M in 2013) into an enterprise location intelligence powerhouse under CEO Jeff Glick's leadership starting in 2016. The company monetized its 70,000 free developer community through a tiered SaaS licensing model based on API calls, with over 90% of revenue now coming from B2B customers including Fortune 500 companies, tech giants like Apple, Microsoft, Samsung, and ride-sharing platforms like Uber. Their Pilgrim technology, built on nearly 12 billion cumulative check-ins (7 million per day), enables contextual mobile marketing and real-time foot traffic analysis that has made Foursquare an essential infrastructure layer in apps across the globe.
