G5 Labs

Boston, Massachusetts, United States · founded 2026 · ≈11 employees · Software Publishers · g5labs.ai

G5 Labs is an MIT CSAIL spinout. Its cloud platform uses a self-learning, bi-directional compiler to turn business requirements and policies into a structured ontology graph that acts as the source code. It sits above frontier coding models as a governance layer. It resolves merge conflicts semantically and can modernize legacy systems for enterprise customers, including in regulated industries. The company came out of stealth in September 2026 with a $14M seed round co-led by Pillar VC and Battery Ventures, and Jeff Dean is among the angel investors.
