Venture studioFresno, California
We grow companies from the root.
Rootstock Studio is where ideas get built. When they're ready for the world, they're grafted off into companies of their own.

Plant, graft, ship.

Plant.
An idea starts here, inside the studio, with shared tools, people, and infrastructure.

Graft.
When it shows real growth, it gets its own identity and structure.

Ship.
It spins off as an independent company. The roots stay. The studio plants the next one.

A scion is the cutting grafted onto a rootstock. Here it means a venture.

03 / About
Nobody buys the rootstock, but it's why the tree is still standing in August.

Rootstock Studio is the Fresno holding company of Dan Donathan, who runs Bellwether IT and co-founded Tonic HQ.
Central Valley growers choose a rootstock for the ground it has to survive in, then graft the fruit on top. The studio works the same way: the roots are shared, and each venture grows on its own.
