Pinetree is an applied research lab in Palo Alto. We build Solari, the infrastructure that AI agents run on: browsers, sandboxes and desktops that start in milliseconds and stay inside the limits you set.
A mind that cannot act is just an oracle.
The world was built for people. Everything we made assumes a human on the other end: reading the screen, filling the form, picking up the phone. For agents to do real work, they need a way in.
That is what we build: the interface between agents and the world, so they can see, act, and speak at enormous scale, inside the bounds we set.
