What Semble AI does

Semble builds custom AI agents trained on how your business actually runs and plugged into the tools your team already lives in. Jonathan and Ethan met studying computer science at Stanford. Jonathan worked at Convergint, one of the world's largest building system integrators, specifically for the purpose of learning how this industry works. They are determined to make Semble the industry standard for construction's back-office.

AI workflow automation for construction back-office

What is your company going to make? Please describe your product and what it does or will do.

We build custom AI agents that automate the back-office workflows in construction companies. These agents learn how a particular business operates and integrate directly with the software tools that teams already use, saving time on manual admin and coordination tasks.

Where do you live now, and where would the company be based after YC?

We live in San Francisco, and the company will remain based here after YC.

Explain your decision regarding location.

San Francisco puts us close to both top AI talent and the kinds of construction and tech companies we want to work with. It's also where we're currently based and working full-time.
