Semantic abstraction layer where natural-language intent becomes source code
G5 Labs is an MIT CSAIL spinout building an AI-native software development platform that treats structured natural-language intent as source code. Its bi-directional ontology compiler converts between business/technical intent and code for semantic merges, traceability, governance, and cost control. Co-founded by MIT professor Tim Kraska, the company publicly announced a $14M seed round co-led by Pillar VC and Battery Ventures when it emerged from stealth in September 2026.
