Instinct Secures $1B Funding, Reaches $10B Valuation in Just One Month

Instinct, a personal AI assistant startup based in San Francisco, has successfully closed a $1 billion Series C funding round, elevating its valuation from $2.5 billion to an impressive $10 billion in just under a month. Founded in 2025 by Noah Shinn, who was only 23 at the time, the company has quickly established itself in the burgeoning field of agentic AI, which focuses on software that performs tasks on behalf of users.

The service, which operates on an invite-only basis, allows users to delegate various errands such as travel planning, grocery ordering, and bill payments through simple text or phone interactions. Instinct's AI agent autonomously manages these tasks without requiring users to share sensitive information like passwords.

Since its launch in August 2026, Instinct has amassed over 100,000 users, a significant achievement given its limited marketing efforts. The recent funding round brings the total capital raised by the company to approximately $1.35 billion, with notable investors including Sequoia Capital, Benchmark, and Coatue.

Despite its rapid growth, Instinct faces challenges related to its infrastructure, as increased user demand has led to delayed response times. The company’s ability to maintain service quality while scaling will be crucial as it moves forward. Currently, there is no disclosed revenue model, raising questions about how the company plans to monetize its services in the future.
