Instinct, the startup behind an invitation-only personal AI assistant, is seeking $1 billion at a $10 billion valuation as access expands and its user base surpasses 100,000, The Information reported Tuesday, citing a person with knowledge of the deal. Sequoia Capital and Benchmark are in talks to lead the financing, whose terms have not been finalized. Founded last year by Noah Shinn, a former researcher at AI customer-service startup Sierra, Instinct connects with users' apps and devices to perform tasks such as shopping, travel planning and subscription cancellations through texts or calls. The company was last valued at $2.5 billion after a Series B led by Index Ventures and Benchmark, bringing total funding to $350 million. The potential financing comes as the service faces capacity constraints while expanding access.
