Instinct AI Funding: $2.5B Valuation Amid Privacy Backlash
Instinct, the invite-only assistant you text, is fundraising at a valuation above $2.5 billion. The Wall Street Journal reported it first on August 26, and Forbes published its own account the same afternoon with the round-by-round detail.
The company behind it was registered in April.
That is the whole story in two sentences: a four-month-old company, a product the public cannot sign up for, and a valuation that has moved twenty-five-fold since spring. It is also the reason the privacy reporting from earlier in the week matters more now than it did then. The money arrived before the answers did.
Three rounds in four months
Forbes reports Instinct raised at least three rounds over a few months, naming California corporate filings for the entity and sources familiar with each deal:
- An early round above a $100 million valuation, led by Sarah Guo of Conviction and Neil Mehta of Greenoaks.
- A $75 million Series A in early August at over $500 million, led by Mamoon Hamid of Kleiner Perkins.
- A round of at least $200 million now in talks at over $2.5 billion, which Forbes reports Benchmark and Index Ventures are in line to lead.
The operating company is Spear Street Technology, Inc., registered in April by Noah Shinn, previously a research scientist at Sierra. Shinn told the Journal he thinks of Instinct as “a one-stop shop to do almost everything.”
Instinct did not respond to Forbes’ request for comment. Neither did Greenoaks, Kleiner Perkins, Benchmark, or Index Ventures. Conviction declined to comment. TechCrunch reported on August 24 that the Kleiner Perkins and Conviction rounds had closed, and also got no response to its questions.
The product still is not public
Nothing about the raise changes access. Instinct remains in private release while the company scales compute, and the only routes in are the waitlist or an invitation from an existing member. There is no published price, because it is currently free.
Investor enthusiasm has been unusually 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 as things it got right. Sheel Mohnot’s “OpenClaw for normal people” is still the line that travels furthest, and it is accurate about the positioning: the agency of a self-hosted computer agent with none of the setup.
Not every test went that way. Forbes surfaced a complaint we had not seen in the launch-week threads: Jason Yeh of Patron Fund asked Instinct to find open dinner reservations and said it went off script and booked a table carrying a $200 cancellation fee. That is a small dollar figure attached to a large question, which is what happens when an agent authorized to act on your behalf decides a task is finished.
The monetization question the round opens up
Forbes raises the part worth watching. Instinct is free today, and the piece lays out two directions it could go: a subscription that acts as a chief of staff, or advertising served against what the agent can see, which Forbes describes as its access to emails, texts, and financial records.
To be precise about it: that is a reporter’s read on the available business models, not an announcement, and Instinct has not said which way it is going. But it is a fair thing to raise, because the company has already written the permissions that would make the second option possible. Its terms take a perpetual and irrevocable license over broadly defined user materials, its privacy notice contemplates personalized advertising, and the Google Workspace carve-out that excludes training is Google’s rule rather than a company-wide promise. Nothing in the documents rules out an ad-supported inbox agent.
A $2.5 billion valuation on a free product with no announced price is exactly the condition under which that question gets answered later, by someone under pressure to justify the number.
What the round did not settle
The reporting that ran two days before the valuation news 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.
Our 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. Almost every task in the viral threads that people actually repeat daily is email, calendar, scheduling, and follow-up. None of that requires an agent watching your screen, holding arbitrary website passwords, or taking a training license over what it sees.
Carly does that layer across Gmail and Microsoft 365: inbox triage, drafted and sent replies, scheduling and rescheduling, meeting prep, booking pages, and recurring workflows. It connects to thousands of apps, and it can be driven from ChatGPT or Claude over MCP.
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 at all. Connections are scoped to what you turn on and revocable one at a time. Free Zapier-style workflows; AI agents from $35 a month.
If you want the broader agent anyway, the 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."
