Sable Raises $45M from Sequoia to Build an 'AI Employee' That Runs Demos
Sable (withsable.com) raised $45 million led by Sequoia Capital and 8VC to build an “AI employee” that runs live product demos in place of a human. Sequoia’s Shaun Maguire and 8VC co-founder Joe Lonsdale led the round, which was announced on July 16, 2026, for a company less than a year old.
It’s one of the larger early rounds for an agentic-AI startup this year, and another sign that investors are betting on agents that do the work on a computer rather than chatbots that reply with text.
What Sable does
Sable’s agent is named Aidan, and it lives on a company’s website. Instead of a chat bubble in the corner, Aidan shows up in a shared browser window that looks like a laptop and actually drives the product while the buyer watches and clicks around alongside it. It’s trained on recordings of a company’s best sales calls, internal docs, and marketing material, so it can see changes on the page and adjust its presentation mid-conversation — and switch between languages on the fly. Notion and Decagon are named among its early customers.
Maguire said a demo in which Aidan switched between English, Mandarin, and Spanish “reminded me of what Stripe did for payments.”
The bet Sequoia is making
Beyond Sequoia and 8VC, the round drew angels including HubSpot co-founders Brian Halligan and Dharmesh Shah, Valor’s Antonio Gracias, and Cognition CEO Scott Wu. CEO Nim Ravid founded Sable to put a human face on AI tooling, and the caliber of backers is a bet that a narrow, high-value job — running a flawless product demo for every website visitor, in any language, at any hour — is worth owning outright. That’s the same thesis behind the broader shift toward AI agents that take action rather than just generate text.
Where this fits — and where it doesn’t
Worth being clear about what Aidan is: a sales-demo agent that lives on a company’s website and works its buyers. It’s not an assistant that does your work across your inbox, calendar, and tools. Those are two different products that the “AI agent” label blurs together.
If what you actually want is an agent handling your own day — triaging email, scheduling, running recurring routines across the apps you already use — that’s the personal-assistant category, and Carly sits squarely in it. It connects to your Gmail or Outlook, calendar, and hundreds of other apps (native connectors, or your own API key for almost anything else), builds custom agents around your actual process, and prices plainly: free, unlimited Zapier-style workflows, with AI agents from $35/month.

"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."
