Maisa AI

Maisa AI is an enterprise AI automation startup founded in 2024 and headquartered in Valencia, Spain, with a U.S. presence in San Francisco. Co-founded by CEO David Villalón, CSO Manuel Romero the company is building what it calls "self-healing Agentic Process Automation" - a category focused on deterministic, auditable, and trustworthy AI agents for regulated industries. Its flagship product, Maisa Studio, lets "citizen developers" (business experts without coding backgrounds) create, test, and deploy AI "Digital Workers" using natural language, similar to training a new hire. The platform is powered by Maisa's proprietary Knowledge Processing Unit (KPU) and a reasoning approach called Chain of Work, which pair large language models with deterministic execution to enforce rules, validate outputs, reduce hallucinations, and keep every step traceable. YouTube demos (@Maisa_HQ) show Digital Workers resolving customer incidents, matching misspelled order numbers, and handling back-office workflows end-to-end. Maisa serves banking, insurance, energy, and manufacturing clients, raised $25M seed in August 2025 ($30.1M total), was named a Deloitte Rising Star, and reports 400% YoY growth with a 5x larger client base.
