Microsoft hires the team behind Sequoia-backed startup Cove; the service shuts down April 1

Microsoft has hired the entire team of Cove, an AI-powered collaboration platform backed by the venture fund Sequoia Capital. The service officially stops operating on April 1, 2026, and all user data will be permanently deleted.

Cove was developing the concept of an AI-native workspace: a work environment where artificial intelligence is built into the architecture of the tool itself, rather than added as a separate module with an "Ask AI" button. Unlike Notion AI, Confluence, Coda or Google Docs with Gemini integration, the startup was building an environment designed from the start for humans and AI to take part in the workflow as equals. Users could work together on documents, projects and knowledge structures inside a single AI environment that suggested links between materials, helped organize information and sped up team decisions.

The startup was backed by Sequoia Capital, one of the most respected venture funds in Silicon Valley. Sequoia's portfolio includes Airbnb, Stripe, OpenAI, YouTube, DoorDash and hundreds of other tech companies. The fund is known for rigorous selection and for betting on the team, not only on the product idea. The exact amount invested in Cove was never disclosed publicly, but Sequoia's involvement was a strong signal: the fund believed in the potential of the people building this product. Those people now work at Microsoft.

The deal structure is called an acqui-hire, or acquisition through hiring. In this format, the corporation does not buy the startup as a legal entity; it hires its employees. The product is shut down, assets may be partially transferred, and the team is integrated into the buyer's organization. Acqui-hires suit corporations for several reasons: fewer antitrust risks, a shorter path from negotiations to actual work, and better odds of preserving team culture and cohesion. For the startup's investors, it is a modest but more predictable exit than waiting a long time for an IPO.

Microsoft actively uses such mechanisms amid intensifying competition for AI specialists. The company is developing several major AI lines at once: Microsoft 365 Copilot (AI in Word, Excel, Teams and Outlook), GitHub Copilot (an AI assistant for developers), Azure OpenAI Service (commercial use of OpenAI models), as well as its own research through Microsoft Research. Specialists in AI collaboration, those who can build work tools that blend people and AI organically, are among the scarcest profiles on the labor market. A team that took a product from version zero to a real offering in a competitive market deserves particular attention.

For current Cove users, the situation is unambiguous: act now. The service closes on April 1, 2026. All data, including documents, projects, shared materials and work history, will be deleted with no possibility of recovery. Those who built their workflows on the platform will have to move to alternatives such as Notion, Confluence, Linear, ClickUp or other team collaboration tools, depending on their specific needs.

Cove's story is not one of product failure. It shows that in today's AI industry, people remain the most valuable asset. A Sequoia-backed startup with an undisclosed valuation ended not through an IPO or a large public deal, but through a quiet move of its team into one of the world's largest technology corporations. The race for AI engineers, researchers and human-computer interaction designers continues, and its participants increasingly adapt the format of deals themselves to the real value being created in the startup ecosystem today.
