About Maisa

At Maisa, we're solving enterprise AI's biggest challenge: trust. We've created the first platform that enables enterprises to build reliable Digital Workers for automating knowledge work without production failures or traditional automation limitations.
We're pioneering Agentic Process Automation for regulated industries. From banking to healthcare, our Digital Workers deliver verified, traceable results that meet the strictest compliance requirements.
Join us in transforming how enterprises work by making AI accountable for mission critical processes, turning Digital Workers into trusted team members, and empowering the people who know the work to finally automate it.
