Instinct raises $1B at $10B valuation as the AI agent race heats up
AI agent startup Instinct closed a $1 billion Series C at a $10 billion valuation, quadrupling its worth in about a month as the agent race between Meta's Muse, OpenAI's dots, and startups heats up.
What happened
AI agent startup Instinct (Spear Street Technology) said on Monday it raised $1 billion in a Series C round, valuing the company at $10 billion, according to Reuters. The round drew investments from Sequoia Capital, Benchmark Capital, and Coatue.
The valuation sprint
The raise quadruples Instinct's valuation in about a month: founder Noah Shinn told the Wall Street Journal last month that Instinct had raised $250 million at a $2.5 billion valuation. TechCrunch notes it's a quick growth round for a startup that launched its invite-only service in August 2026.
What Instinct does
Instinct is developing a personal agent that can perform day-to-day tasks autonomously. The startup was founded in 2025 by 23-year-old Noah Shinn, who previously worked at Sierra, an AI customer service startup run by Salesforce co-CEO Bret Taylor. Users interact with Instinct through text or calls and can ask it to handle tasks such as planning trips, buying groceries, booking tickets, and canceling subscriptions. When asked to perform a task, Instinct uses its own phone number and computer. A new "concierge" feature can make phone calls on a user's behalf to make bookings at places that don't offer online booking. Barron's notes the catch: Instinct is still in early access, so most people can't actually use it yet.
Why it matters
Interest in AI agents has surged since Meta's Muse drew millions of downloads earlier this month, and OpenAI answered Tuesday with always-on "dots" agents inside ChatGPT at DevDay 2026. Instinct's raise shows venture capitalists are betting that agents could automate entire workflows traditionally handled by employees or software applications — the same bet driving both giants.
