Two weeks ago, Y Combinator put out their Summer 2026 Request for Startups. The first item on the list was something they called a "Company Brain" — a system that pulls knowledge out of scattered sources, organizes it, and turns it into something AI can actually use.
The phrasing felt familiar. We've been building exactly that for over a year.
Why we started
We started Webair AI because we noticed something simple. The AI models had gotten really good. We were using ChatGPT, Claude, and Gemini every day. But none of them knew anything about our actual business.
Every conversation started over. We pasted the same context. We re-explained the same clients. We fixed the same wrong tone in the same drafts. The models were brilliant in general and useless in particular.
The problem wasn't the AI. The problem was that all the information our business actually ran on was scattered. Some in Gmail. Some in Drive. Some in Slack. A lot of it just in people's heads.
We thought: someone has to organize all of that into one place so the AI can read it. So we did.
The early version
The first version of the Knowledge Hub was rough. We dumped emails, contacts, projects, and decisions into a structured database and made a search interface. It worked, but it wasn't enough.
The thing we realized fast: a giant pile of documents isn't a brain. A brain has structure. It knows that this person is connected to that company, that this decision applies to that project, that this preference is personal but that fact is business-wide.
So we built Cortyx — the engine that sorts everything into the right layer. Personal memory. Business memory. Operational memory. Each layer is organized further by facts, preferences, summaries, and things about you.
That's the structure that makes the difference. A search bar can find files. A Company Brain understands them.
The iMessage moment
The biggest insight came when we started thinking about how the brain would actually grow.
Most AI tools live behind a login. People open them a few times a week if they remember. The "brain" barely fills in. We didn't want that.
iMessage was the answer. You already text a hundred times a day. You text your team, your spouse, your clients. So why should logging a note about a client require opening a separate app?
We made Webair AI a contact you save in your iMessage. You text it the way you text anyone. Every text becomes part of your Company Brain. That's how it grows — from the way you already work, not from forced data entry in a portal you forget about.
Why privacy was non-negotiable
When you chat with ChatGPT, the memory those tools build about you is theirs, not yours. They can see it. They can use it. They could sell it to an advertiser someday.
We didn't want to build that. Your business knowledge is the most sensitive thing you own. So we built Webair AI so we can't see it.
Your brain is encrypted in transit and at rest. It's never sold. It's never used to train any public model. Webair AI staff cannot read your private memory. You can export it. You can delete it. SOC 2 Type II. GDPR-aligned. HIPAA-ready.

What YC named
When the YC Request for Startups dropped, the phrase "Company Brain" took off. Within days, several startups were rebranding. LinkedIn filled up with founders claiming they'd been building "the company brain" all along.
That's fine. We think YC is right — every business is going to need one. The more people building toward it, the faster everyone gets there.
But here's the thing. We didn't rebrand last week. The product has been live. Our customers have been building their brains for months. We just didn't have a name for the category. Now we do.
What's next
The Knowledge Hub is the foundation. What it unlocks is agents — Webair AI suggesting drafts, follow-ups, schedulers, and workflows from your own data. That comes during Beta, with your approval before anything runs.
Y Combinator was clear about why this matters: "AI agents can't work reliably if your knowledge is scattered." That's been our thesis from day one. Build the brain first. The agents come after.
If you've been trying to make AI useful for your business and failing — that's the problem we solve. Read more about what a Company Brain is, or sign up and start building yours today.
