Answers are derived from the roster record shown on this page — filing status, last round and confirmed marks. Where the record is silent, the answer says so rather than guessing.
Instinct, operated by Spear Street Technology, is a San Francisco consumer AI company building a personal agent reached by text message or phone call rather than through a new app. It connects to messaging (iMessage, WhatsApp) and email and is trained to operate a phone and a computer directly, so it can answer messages, keep a calendar, book travel and restaurants, buy groceries and tickets, cancel subscriptions and coordinate home services on the user's behalf. Founder Noah Shinn, 23, was a researcher at Sierra and is known in the agent-research community for the Reflexion work on verbal self-correction in language agents and for the tau-bench tool-agent benchmark. The funding history is unusually compressed: a seed led by Conviction with Greenoaks participating, a $75M Series A at a $500M+ valuation led by Kleiner Perkins in early August 2026, and a $250M Series B co-led by Index Ventures and Benchmark at a $2.5B post-money announced 2026-08-26, for $350M raised in total. Two caveats belong on the record. Founding date: TechCrunch describes the company as founded in 2025, while Forbes reports the legal entity was registered in San Francisco in April 2026 — the 2025 date here reflects when the effort began, not incorporation. And the product is not generally available: access is invite-only while the company secures compute, it is free with no disclosed revenue model, and TechCrunch reported on 2026-08-24 that early users and security researchers raised concerns about the breadth of device permissions the assistant requests and the scope of its terms of use.
