Instinct, a personal AI agent startup, raised $1 billion in Series C funding from Sequoia Capital, Benchmark and Coatue at a $10 billion valuation.

Four Times the Value in Weeks

The valuation is up from $2.5 billion when Instinct raised a $250 million Series B in August 2026, only weeks earlier.

An Agent That Finishes the Job

Founded by Noah Shinn, Instinct is designed to handle personal tasks from start to finish rather than only offering recommendations: planning trips, ordering groceries, canceling subscriptions, coordinating schedules, making reservations and dealing with service providers. It uses its own computer and phone capabilities to act on a user's behalf.

Travel Leads the Way

Instinct launched as an invite-only service in August. Its founder said more than half of transactions on the platform are travel-related.

Your Next Customer May Be an Agent

Agents like Instinct will call, email and transact with businesses on people's behalf. Clear online booking, cancellation and support paths make it easier for those agents — and the customers behind them — to deal with you.
