“Can email + attorney-in-the-loop become the durable trust layer that makes AI agents usable for high-stakes legal work?”
Mixus was founded in 2025 by the Phantom Auto team, applying the 'remote human supervision' pattern from autonomous vehicles to AI agents. Initially positioned as a horizontal email-based AI agent platform (per July 2025 TechCrunch coverage), the company has narrowed its 2026 go-to-market to legal — specifically AI redlining, deal modeling, and venture financing workflows for Am Law firms — with attorney-in-the-loop approval as the core trust primitive.
Mixus was founded by Shai Magzimof and Elliot Katz and is founded in 2025, headquartered in San Francisco, CA, United States.
Mixus has raised $2.6M in total (latest round: Seed).
