Sol Browser
Sol Browser is a San Francisco startup (Y Combinator Fall 2025) building a browser designed to work as a developer's IDE. It lets engineers run multiple AI coding agents - Claude Code, Codex, Cursor - in parallel from browser tabs, alongside terminals, diff viewers, running apps, docs and pull requests. The company began as Inspector, an AI IDE that connected the browser to the codebase so agents could see the same visuals, elements and logs a developer sees, then expanded that idea into a full browser workspace. Founded by Quentin Romero Lauro and Michael Klikushin, it operates as Sandbox Technologies, Inc.
Imbue
Imbue is a San Francisco AI research lab building agents that can reason and code. Founded in 2021 as Generally Intelligent and renamed in 2023, the company is led by CEO Kanjun Qiu and CTO Josh Albrecht. After a $200M Series B that valued it above $1B, Imbue is focused on practical agent tools - most visibly Sculptor, a UI for running parallel coding agents safely in containers - guided by a mission to keep humans in control of powerful AI.
