- Instinct, an invite-only AI agent that can text, call and act across a user’s apps and accounts, has raised $250 million in Series B funding co-led by Index Ventures and Benchmark.
- The round values the startup, founded by 23-year-old Noah Shinn, at $2.5 billion and brings its total funding to $350 million.
- Instinct’s valuation has jumped from $50 million to $2.5 billion in just four months, as investors race to back personal AI agents capable of taking actions rather than simply answering prompts.
At just 23, Noah Shinn is turning his bet on personal AI agents into a $2.5 billion startup. Shinn, founder of Spear Street Technology, the company behind AI assistant Instinct, has raised $250 million in a Series B round co-led by Index Ventures and Benchmark, taking the startup’s total funding to $350 million.
Four months ago, Instinct didn’t have a dollar valuation at all.
“I’m thrilled with everything our early users are doing with Instinct,” Shinn wrote in a post on X on August 26, listing road trips, grocery runs, concert tickets and cancelled subscriptions his testers say the agent has handled. One person, he added, is using it to plan a wedding.
From $50M to $2.5B in four months
An early backing from Conviction’s Pranav Reddy and Greenoaks’ Neil Mehta valued the company at $50 million. By early August, Kleiner Perkins partner Mamoon Hamid led a $75 million Series A at a $500 million valuation. Three weeks later, Benchmark and Index Ventures priced it at five times that.
Few companies see their valuation move that fast before they’ve even launched.
Shinn previously worked as a research scientist at Sierra, the AI company that builds customer-service agents for businesses. He registered Spear Street Technology, the entity behind Instinct, in California in April.
The pitch is simple: connect Instinct to your phone, computer, email, calendar and messaging apps, then delegate by text or phone call instead of opening yet another app. It’s still invite-only, and it hasn’t said when that changes.
An agent that wants more access than most
Rabbit’s assistant and the agent products from OpenAI and Google mostly stick to a narrower task or device. Instinct wants your screen, your audio, your location and your inbox all at once, and that appetite has already caused a real incident, not a hypothetical one.
Moxxie Ventures founder Katie Jacobs Stanton said the agent sent an email on her behalf without asking, then kept reading her inbox for hours after she cut off its access. Instinct’s terms reportedly give the company a perpetual, irrevocable license to that data, including screen captures, cursor movements and keystrokes, to train its models.
The AI agents market is on track to grow from around $11 billion this year to more than $50 billion by 2030, and personal-assistant agents are one of the categories pulling that growth.
It’s not hard to see why investors are moving fast. Whether users will move as fast, once they understand what “perpetual and irrevocable” means for their own inbox,is the question nobody backing this round has had to answer yet.
