What is Instinct?
Instinct is a closed, cloud-hosted, invite-only AI personal assistant that runs a proprietary model on Spear Street’s servers and works through iMessage. The material tracks its fundraising trajectory and its position among competing agentic assistants.
Release history
- Sep 2026 - Jason Calacanis said Instinct had raised at roughly $50 million pre-money less than five months earlier, then $400 million pre, then a couple of billion pre, and was rumored to be raising north to $10 billion.
- Sep 2026 - Calacanis said an Instagram reel he made about Instinct drew over a thousand DMs asking for invite codes, a first for him.
- Sep 2026 - Nathaniel Whittemore said Instinct is less technical and usable by a much larger population than Hermes and OpenClaw, which only techies could use and which broke often.
- Sep 2026 - Harry Stebbings said reward hacking cannot be solved today, so he trusts no instincts, calling it a hopeless category.

Instinct. An AI company that went from $50M to a rumored $10B pre-money in under five months, generating unprecedented consumer demand (1,000+ invite DMs on one reel), but still has minutes-long response latency and no confirmed killer app.

An Instagram reel about Instinct generated over 1,000 DMs requesting invite codes, which Jason Calacanis called an unprecedented consumer demand signal.
“I did an Instagram reel on it. I had over a thousand DMs asking for invite codes. I've never had a thousand DMs on the back of a reel.”Jason Calacanis · 17 Sep 2026
Reward hacking in LLM-driven personal assistants is currently unsolvable, making personal AI agent products like Instinct a hopeless category today.
“I don't think today you can solve reward hacking. So I don't trust any instincts. I think this is a hopeless category today.”Harry Stebbings · 3 Sep 2026
Successive AI agent tools (OpenClaw, Hermes, Instinct) show a clear diffusion pattern where each generation reaches a larger, less technical user base, challenging the assumption that agent tooling remains a developer-only domain.
“Only techies could use OpenClaw, but it broke a lot. Hermes broke less. Instinct is less technical and usable by a much larger population than Hermes and OpenClaw.”Nathaniel Whittemore · 2 Sep 2026
There is a 'Dunar number' for AI agent rule sets: beyond roughly 40 to 70 gates on a process, rule conflicts make agent outcomes unpredictable.
“There's a Dunar number for rules where you get out to 40 50 60 70 gates on a process that poor instinct in Grockot can't decide.”Harry Stebbings · 10 Sep 2026
