Team
Bast is built by people who believe AI should show its work — and who put their own names behind that standard.
CEO & Founder
Beth founded Bast to build trusted, explainable AI infrastructure: AI grounded in approved knowledge that can show, for every answer, exactly which source it drew from. Her expertise spans AI/ML, data strategy, and the organizational work of making AI accountable to the people who use it.
CTO
Thanh leads the architecture of Bast's verification layer — the system that sits between an organization's approved knowledge and the model's output, checking scope and source grounding before any answer ships. His expertise spans AI architecture, source-grounded AI, AI explainability systems, AI verification layers, conversational AI design, and AI guardrails.
