Instinct AI Funding: $1B Series C at a $10B Valuation
Instinct, the invite-only assistant you text, raised a $1 billion Series C at a $10 billion valuation on September 28, 2026, from investors including Sequoia Capital, Benchmark and Coatue. Instinct confirmed the round in a press release. It came one month after a round that valued the company at $2.5 billion.
The company behind it was registered in April.
So in five months: a valuation that went from about $100 million to $10 billion, a product the public still cannot sign up for, and no published user numbers. The money keeps arriving before the answers do.
Four rounds in five months
- An early round above a $100 million valuation, led by Sarah Guo of Conviction and Neil Mehta of Greenoaks, per Forbes.
- A $75 million Series A in early August at over $500 million, led by Mamoon Hamid of Kleiner Perkins, per Forbes.
- A $250 million Series B at $2.5 billion, co-led by Index Ventures and Benchmark, announced August 26. It brought total funding to $350 million, TechCrunch reported from the company’s statement to the Wall Street Journal.
- A $1 billion Series C at $10 billion, from investors including Sequoia, Benchmark and Coatue, announced September 28. The Information had reported the talks earlier in the month.
That puts total funding at about $1.35 billion by our count, and the valuation up fourfold in a month.
The operating company is Spear Street Technology, Inc., registered in April by Noah Shinn, previously a research scientist at Sierra. Instinct offered no interviews with Shinn for the Series C. His statement: “This funding helps us bring Instinct to more people and continue building the future of personal AI.” The company has not shared user numbers or growth metrics, TechCrunch noted.
The product is still invite-only
The raise did not open the doors. Instinct is still invite-only, with a waitlist. Sign-up is no longer US-only: when we checked on October 6, it accepted phone numbers from 83 countries. There is no mobile app: you text or call it. There is no published price, because it is currently free. Details are in Instinct pricing.
What did change since August is how much it does:
- Concierge places phone calls to businesses for you, for appointments at places with no online booking.
- A trusted-person network lets your Instinct coordinate plans with your friends’ Instincts.
- Shopping checkout. Since September 28 it can search Shopify merchants and pay with Shop Pay.
Investor enthusiasm has always been specific about why. Guo wrote on X that having an AI product you trust to execute transactions and navigate websites is amazing, listing restaurant bookings, marathon entries, campsite reservations and general purchases. Sheel Mohnot’s “OpenClaw for normal people” is still the line that travels furthest.
Not every test went that way. Jason Yeh of Patron Fund told Forbes he asked Instinct to find open dinner reservations and it booked a table carrying a $200 cancellation fee, a small dollar figure attached to a large question about an agent deciding a task is finished.
How a $10 billion free product makes money
The day after the Series C, Instinct gave the first concrete answer. Instinct Selections began pushing curated product picks for dining, travel and shopping, which TechCrunch called a potential new revenue stream. Shinn said the picks come from partners such as “local chefs, designers, architects, travel guides.”
Users noticed what the picks were drawn from. “I didn’t need to buy carry-on luggage, sunglasses, or a brim hat,” wrote Shruti Gandhi of Array VC. Chat Joglekar wrote that Instinct “started to suggest products that I should buy based on what I had in email and upcoming trips.”
That is the question Forbes raised in August, now with a first data point: a subscription that acts as a chief of staff, or revenue earned against what the agent can see. The terms and privacy policy Instinct published on August 26 dropped the perpetual license and the reference to personalized advertising, and say Instinct does not sell user information. Training on user data is still on by default, the opt-out applies only going forward, and the Google Workspace carve-out that excludes training and ads is Google’s rule rather than a company-wide promise.
A $10 billion valuation on a product with no price is exactly the condition under which that question gets answered by someone under pressure to justify the number.
What the rounds did not settle
The reporting from launch week is still the open file:
- Claire Vo disconnected her Google account and found Instinct still held copies of email already pulled into its own records. TechCrunch reports a deletion tool for external data has since been added to settings. There is still no public postmortem describing what was retained or for how long.
- Alex Cohen emailed instructions into his own inbox and got the agent to act on them, a plain prompt-injection result.
- Katie Jacobs Stanton reported an email sent without her approval and disconnected email access.
The competition also arrived. Meta’s Muse does much of what Instinct does and topped the US app stores; OpenAI launched dots the same week as the Series C. Comparisons: Meta Muse vs Instinct and ChatGPT dots vs Instinct. The full breakdown of what the terms permit is in why people hate Instinct AI, and the product itself is covered in what Instinct AI actually is.
If you want the useful part now
The demand Instinct proved is real and narrower than the product. Most of the tasks people repeat daily are email, calendar, scheduling and follow-up. None of that requires an agent holding arbitrary website passwords or recommending luggage from your inbox.
Carly does that layer across all of your Gmail and Microsoft 365 inboxes: triage, drafted and sent replies, scheduling and rescheduling, meeting prep, booking pages and workflows that start the moment an email or lead arrives. It works on the web and over SMS, so you can text Carly too, and it connects to thousands of apps. Inside ChatGPT or Claude, add the Carly plugin or the Carly connector.
The commitments are written down rather than implied by a funding round. Carly’s privacy notice says customer data, including Google and Microsoft data, is not used to train AI or machine-learning models, and that its model providers cannot retain it or train on it either. Carly’s terms take no content license. Free Zapier-style workflows; AI agents from $35/month. Get started with Carly.
If you want the broader agent anyway, the Instinct alternatives worth testing covers what else is shipping.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
