Blackboard / A startup lab

We build products.
And the tools
behind them.

An independent lab turning ideas into products and companies. We build the tools we need along the way, and share them so you can build with them too.

02 / Built in the lab

The tools are
just the beginning.

Blackboard is a place to build businesses around good ideas. Our tools give us a foundation to start from, experiment with, and improve as the work takes shape.

Every product has its own purpose and identity. What connects them is how we build: small teams, hands-on craft, and tools we use ourselves.

Meet the lab
