Had a blast hosting a small group of @sablehq friends, customers, and investors to meet Aidan!
Thank you @sequoia’s @shaunmmaguire and @8vc’s @JTLonsdale for bringing the energy 🚀

Today, we're introducing @Intelligence_ai.
In 6 months, as a team of 10, we scaled from $5M to $60M ARR and 5.5M users across 190+ countries.
We raised a $7.9M seed, led by @IndexVentures with participation from @conviction, @A_StarVC, and @combinator to build DesignArena, a universal interface for accessing and evaluating the world's AI capabilities.
Most evaluations try to simulate the real-world. We believe the real-world is the ultimate verifier.
People come to @DesignArena with a request. Models compete to fulfill the request, and users determine what works best for them.
Their live user behavior evaluates the models, improves how work is routed, and helps people access the right intelligence.
We've helped the world's leading frontier labs break the news on their SOTA capabilities.
What's the limit? Join us and find out.

About eight months ago, early in my journey at Notion, I submitted a contact form on the @sablehq website and got connected with @Nim_Ravid1
At the time, I was trying to answer a difficult question: how do you build and grow a global consulting ecosystem across 47 countries as a team of one?
My entire career in partnerships had followed a familiar formula. Carve partners into books, hire more partner managers, and repeat. I joined Notion motivated to break that mold, but I needed to find the right tools to make it possible.
When @Nim_Ravid1 shared his vision for multimodal agents that could speak, see, use a browser, and guide people through personalized experiences, I was blown away.
Sable gives us the ability to train and develop partners globally, in any language and at any hour. More importantly, it allows me to shape an agent around the judgment, expertise, style, and patterns I would bring to those conversations myself.
That means more partners can access the judgment and expertise they need to grow their businesses, serve their customers, and help bring Notion to more organizations around the world.
It gives us a way to scale the partner manager, not just the partner content.
Huge congratulations to Nim and the entire Sable team. I’m incredibly excited about what this technology can do today and where it goes next.
Introducing Aidan, your newest AI employee
Aidan is the first computer-using AI built for realtime conversation
We’ve raised $45M from @sequoia and @8VC to bring Aidan to the world
@NotionHQ and @DecagonAI already use Aidan to run customer interactions. This is how @sablehq works:

Thanks @FortuneMagazine for sharing our story fortune.com/2026/07/16/ai-em…
Building with @chensterman, @itaprf, @Lindaaa_He has been the time of my life

Everyone knows marketing, sales, and deployment convert better when personalized to the buyer and their specific needs. Previously you could only scale this personalization via more employees, but now you can scale it with Aidan at @sablehq.
They've unlocked a level of personalization and real time engagement that couldn't exist before the latest advancements in computer use and vision models. We're excited to partner with them, and tell your front office teams to give them a try.

One of the biggest constraints on growth has always been the ability to scale human judgment.
At Palantir, we saw firsthand why exceptional people matter in helping customers understand and deploy transformative technology. The hardest work wasn't explaining the technology. It was understanding context, reasoning through novel situations, and helping customers make better decisions. Until now, that hasn't been scalable.
That's changing.
@8vc led @sablehq's $45M raise alongside my friend @shaunmmaguire at @sequoia. I'm honored to be joining the board.
The best founders recognize platform shifts early and execute even faster. Nim Ravid and the Sable team saw where multimodal AI was heading early and built with remarkable speed.
Sable is building an AI employee that can see what a customer sees, interact with the product alongside them, and reason through complex problems in real time.
What felt like science fiction a year ago is already working in production with some of the fastest-growing AI companies in the world.
We’re excited to work alongside @Nim_Ravid1, Linda, Leon, Itamar, and the entire Sable team as they build one of the defining AI companies of this next era.

Today we're bringing @sablehq out of stealth.
We've been building Aidan — the first AI employee that learns how your product works, then runs live sales conversations at scale.
But Aidan isn't just a chatbot with a voice. Aidan demos inside a live, shared environment of your product: he sees it, reacts what you do in the moment, and drives it with his own hands — all mid-conversation.
We've raised $45M led by @sequoia and @8vc , joined by BoxGroup, Sabrina Hahn, SVA, and Valor. @NotionHQ and @DecagonAI already trust Aidan with some of their most important customer conversations.
Incredibly grateful to be working with @Nim_Ravid1, @Lindaaa_He, @itaprf, and our incredible team. Watch how Aidan works: 👇
