Viral AI agent Instinct raises $1B Series C at a $10B valuation

What happened

Consumer AI agent startup Instinct — which launched its invite-only service in August 2026 — has announced the close of a $1 billion Series C round, just one month after its prior funding round that valued the company at $2.5 billion post-money. The AI agent can independently complete user-delegated tasks including travel bookings, bill payments, and subscription cancellations using its own dedicated phone number and computer access. It recently added features to make phone reservations on users' behalf and enable cross-user agent collaboration between friends. Currently, the service only interacts with users via SMS, with no standalone mobile app launched to date.

Background

Instinct closed its prior funding round just one month ago, at a $2.5 billion post-money valuation. The consumer AI agent space is currently experiencing booming market interest: Meta's competing AI assistant Muse has topped U.S. app store download charts, racking up millions of cumulative downloads. Instinct previously faced controversy for its privacy policy that collected excessive user data, and has since updated its policy framework.

Why it matters

This round is a clear signal of intense capital market enthusiasm for consumer AI agents that can complete real-world, actionable tasks. For developers, the fast-growing space will drive ecosystem investment toward task automation capabilities. For end users, these actionable AI services will become more widely available faster, while also spurring improvements to personal privacy protection regulations.

In their words

“Our goal in building Instinct is to create the best personal agent that can handle deeply personalized, day-to-day life needs. This funding will help us reach more users as we co-build the future of personal AI — our journey is only just beginning.”

Noah Shinn, founder of Instinct

What to watch

Going forward, stakeholders can track Instinct’s core operational metrics disclosures, progress on launching its standalone mobile app, user feedback on its updated privacy policies, and competitive performance against rival Muse.
