The first number behind Instinct's $10 billion mark: half the book is travel
A day after Sequoia, Benchmark and Coatue paid $1 billion at four times last month's price, Instinct founder Noah Shinn disclosed the book behind the mark: approaching $1 billion in annual transactions, more than half of them travel bookings, on a calculation he did not specify. That is gross volume, not revenue.

A number lands the day after the wire
On 29 September, the day after Spear Street Technology closed a $1 billion Series C valuing its personal agent Instinct at $10 billion 23, founder Noah Shinn went on a podcast and attached the first numbers to the mark. More than half of all transactions on the platform are travel bookings, and annual transactions are approaching $1 billion, Shinn told investor Patrick O'Shaughnessy, without specifying how the rate is calculated 1. His pitch for the product, founded in 2025 after his work at Bret Taylor's Sierra 3: a user says "Hey, I need to be in New York tonight; it's urgent" 1, and an agent with its own phone and computer, no app required 9, handles the rest.
Volume is not revenue
The $10 billion is equity; the $1 billion is other people's bookings passing through. Sequoia, Benchmark and Coatue paid four times the $2.5 billion the company carried a month earlier 23. What the price buys: 14 employees 1, invite-only access since August 2, no disclosed user counts 2, no mobile app 2, and an early-access gate most people cannot yet pass 4. Bloomberg Intelligence sizes the consumer-agent transaction pool at $1 trillion 4. Between the bookings and the equity sits the one number nobody has disclosed: the take rate. Shinn also claimed 10% day-over-day growth, a pace that would multiply volume roughly 800-fold in ten weeks if it held 1.
Every fresh print marks the next
Instinct's round is not even the largest private AI mark of the week. Modal Labs is in talks to raise $750 million at a valuation approaching $15 billion, triple its May mark, on annualized revenue that reached roughly $300 million 5. Baseten stands near $26 billion, Fireworks AI closed at $17.5 billion on more than $1 billion of ARR, and Fal is aiming at $8 billion 56. Sequoia led Fal's last round and now backs Instinct as well 63; every new print gives the portfolio a mark to point at.

Free rivals, halved costs
Meta is giving the rival product away. At Connect on 23 September, Mark Zuckerberg said Muse stays free for a huge number of tokens and that Meta will profit by "taking a small fee from transactions," charged to merchants, with Expedia among the new travel connectors 7. Muse has already topped US app store charts 2. The same week, OpenAI cut GPT-6 API prices by half or more, permanently 8: the models underneath agents are deflating while the equity above them quadruples.
The tell is the take rate
Instinct also competes with Khosla-backed Wajo 1, but the encirclement that matters is Meta's: free distribution, merchants paying the fee, Expedia wired in 7. The first disclosed fee on a single travel booking will say what a half-travel, approaching-$1-billion book actually earns, and whether 14 people can hold it.
