The team behind Cove, a Sequioa-backed AI collaboration platform, has joined Microsoft. The company was founded in late 2023 by Stephen Chau, Andy Szybalski, and Mike Chu, who worked on Google Maps features like Street View. Cove was working on an AI-powered collaboration board that could generate blocks for tasks like trip planning. The team will join Microsoft and the product will shut down on April 1, and all user data will be deleted. The startup has refunded all subscriptions for March and offered a data export process.
