Viral AI agent Instinct raises $1B Series C at a $10B valuation

It’s only been a month since AI assistant startup Instinct announced a fundraise that valued it at $2.5 billion , and now the company has already raised another $1 billion, from investors including Sequoia Capital, Benchmark Capital and Coatue, valuing the company at $10 billion.

The news of the company’s fundraising efforts was reported earlier this month by The Information . In a press release on Monday, Instinct confirmed this was a Series C round — a pretty quick growth round for a startup that launched its invite-only service in August 2026.

The quick fundraises demonstrate the fervor around a new class of consumer AI agents, which can not only answer questions and engage in conversations, but can actually get things done for their users, whether that’s booking travel plans or restaurant reservations, making purchases, paying bills, canceling subscriptions, conducting tedious research, ordering groceries, and more.
