AI Startup Instinct Raises $1 Billion at $10 Billion Valuation, Quadrupling Its Worth in a Month

The Series C round drew backing from Sequoia Capital, Benchmark Capital and Coatue, Reuters reported. Founder Noah Shinn had told the Wall Street Journal last month that Instinct previously raised $250 million at a $2.5 billion valuation — a figure the new round has now left far behind.

Instinct is building a personal AI agent that can carry out everyday tasks on its own rather than simply answering questions. Users text or call the agent — also called Instinct — and it uses its own computer and phone to get the job done: planning trips, ordering groceries, booking tickets, cancelling forgotten subscriptions and making reservations.

The company has recently expanded beyond digital tasks with a concierge offering that can place phone calls to businesses on a user's behalf to secure bookings, the firm said Monday.

At the center of the investment is a wager that the next phase of consumer AI belongs to systems that take action. Chatbots taught millions of people to ask AI for information; agent companies are betting users will increasingly ask it to do things.

The context is hard to ignore: Meta's Muse AI assistant has "taken off electrically," in the words of Deutsche Bank analyst Benjamin Black, with more than 3 million U.S. and Canadian downloads since its September 8 debut, according to Sensor Tower.

Instinct's product is not yet available to the general public. Access remains invitation-only after an initial launch to about 200 friends and family members. MarketWatch reported the company has only 14 employees — making the $10 billion valuation one of the most extreme per-employee figures in startup history.

Shinn, 23, founded the company in 2025 after working as a research scientist at Sierra, the AI customer-service startup run by Salesforce co-CEO Bret Taylor. He previously conducted machine-learning research at Northeastern and MIT, where he co-developed Reflexion, a framework that lets a language model check its own output and use feedback to improve subsequent attempts.

Shinn told podcaster Patrick O'Shaughnessy that the company is "approaching" over $1 billion in annual transaction volume.

The company used Monday's announcement to spotlight privacy guardrails for a product that connects to users' email, messaging, screens, audio and location.

Instinct said its privacy features — including isolated sandboxes and short-lived local credentials — are continually being improved, and that a new active detection system helps catch subtle hallucinations in the agent's responses.

"This funding helps us bring Instinct to more people and continue building the future of personal AI," Shinn said in a statement. "We're building Instinct to be the best personal agent that can handle the deeply personal nuances of everyday life."

The round is the latest sign of venture capital's near-insatiable appetite for agentic AI. Investors are betting that agents could eventually automate entire workflows traditionally handled by employees or software applications — and with a 23-year-old founder, 14 employees and a $10 billion price tag, Instinct has become the boom's most eye-catching symbol.
