Chat + Personal AI agents are booming!

[Wall St Engine @wallstengine]

Instinct is in talks to raise about $1 billion at a roughly $10 billion valuation, less than a month after raising $250 million at a $2.25 billion pre-money valuation.

The 23-year-old founder Noah Shinn is building a personal AI agent that can operate software and complete tasks like answering emails, negotiating bills and booking reservations.

Instinct now has more than 100,000 users and has already run into compute capacity constraints as demand grows.

Its valuation has gone from roughly $50 million in the spring to $10 billion under discussion today.

@poteto @bot My problem is I've reach the 50 bots maximum limit.

Can we get an increase for Cursor Ultra users?
