About Phase Change
Pioneering symbolic AI
Phase Change Software is an innovative AI company headquartered in Lakewood, Colorado. Founded by Steve Bucuvalas and led by CEO Gary Brach, we specialize in cognitive AI technology that transforms how enterprises understand their most critical software assets.
In a world flooded with statistical AI that guesses and hallucinates, we chose a different path: symbolic AI that knows. Our knowledge graph platform provides mathematical certainty about business logic, enabling enterprises to finally decode the trillions of lines of COBOL that power the global economy.
Truth Over Probability
We believe AI should provide verified facts, not educated guesses. Every answer from our system is traceable to specific source code.
Enterprise-Grade Trust
FedRAMP-ready deployment, SOC 2 compliance, and zero-trust architecture. Built for the most regulated industries on earth.
The COBOL Economy
240 billion lines of COBOL run the world's banking, insurance, and government systems. We're making that knowledge accessible to everyone who needs it.
Human-Centered AI
We don't replace developers — we give them superpowers. Our tools amplify human expertise with machine precision.
