Baz develops precision coding agents that automatically review code changes, detect bugs, enforce coding standards, and fix issues. Its new product Baz Planner shifts code review to the planning stage, intercepting entire classes of defects against architectural standards before code is written—early customers have reported rework reductions of over 65%. The company was founded in 2023 by alumni of Bridgecrew (acquired by Palo Alto Networks for approximately $200M in 2021); its code review model has outperformed OpenAI and Google on public benchmarks.
