What it was: With Deco, founders Devin Abbott, David Chen, Spencer Liolios, and Gavin Owens created a tool to speed up mobile app development and "bridge the gap between designers and engineers."
Why Airbnb bought it: Airbnb still needed more talent to help develop its own platform, and since it had already been working with Deco, the company felt confident bringing on its team.
What happened to the company: Deco's founders joined Airbnb, discontinued support for their product, and let the development environment they had built live on as an open-source tool.
How much Airbnb paid: Undisclosed.
