US-based personal AI assistant developer Instinct raised $1 billion in a Series C funding round joined by Sequoia Capital, Benchmark Capital and Coatue. The company, founded in 2025, saw its valuation rise to $10 billion. Founded by Noah Shinn, Instinct will use the investment to expand its platform and develop its technology.
Tasks the agent can perform:
- Make travel and restaurant reservations
- Complete shopping and grocery orders
- Pay bills
- Cancel subscriptions
- Conduct research
- Make appointments by phone
Instinct communicates with its users via SMS and messaging; it does not yet have a mobile app.
Why it matters
Instinct’s approach positions the AI assistant not as a separate app, but through the SMS and messaging channels users already use. While this choice brings different tasks such as reservations, orders, payments and appointments together in a single communication flow, it also directly affects how the service is used. The lack of a mobile app means that messaging infrastructure and the user experience on these channels will be decisive in expanding the platform’s reach. The investment’s aim of developing the technology and increasing access shows that the company is focused on expanding both the scope of tasks and the way it reaches users at the same time. What remains unclear is how these plans will be reflected in the existing messaging-based structure and at what scale the app-free model will be sustained.
