Hey YC, we’re João, Lucas, and Sergio, cofounders of Mesmer — Cursor for CTOs.

We’re repeat founders and CTOs behind startups like Glio (S13) and Origin Financial ($400M). In every team we built, we ran into the same challenge: each new customer, employee, and feature made it harder to understand what was actually going on. We spent our days in back-to-back meetings and chasing status updates, and forced our teams to do busywork just to keep us in the loop. Yet we still didn’t see problems until something broke.
AI is already making the 10x engineer possible. But there’s no solution that helps product development orgs — and product leaders — 10x themselves. That’s what we’re building.
Enter Mesmer
Mesmer gives founders and CTOs full context on their org without drowning in meetings or chasing people for updates. It watches the work itself — code, specs, designs, meetings — to build a live, detailed picture of what’s going on. Our customers can keep their teams fast, flat, and focused as they scale — and free from busywork.
We are starting with an AI chief of staff for product development orgs. Every week, it delivers a report showing what actually happened across all in-flight projects: what moved forward, what shipped, and what’s stuck. Founders and CTOs can then ask questions and get in-depth answers based on their team’s actual code, specs, and designs, like:
- Why is this project slipping?
- Who’s the best engineer to unblock it?
- What architecture did we use in this repo?
- How does the business logic work for this categorization engine?
- What changed in the roadmap last week?
We’re already live with 10+ companies worth over $3B and have reviewed over 70M lines of code along the way. We’d love to help you, too.
Special Offer
We’re onboarding companies as fast as we can, but, if you’re a CTO leading a team of 20+ engineers (or know someone who is) email me at joao@mesmer.co and we’ll skip the line to help you run a flat, fast, focused org right away.
