Ambral

Ambral is building the AI stack for turning enterprise history into evals, environments, and company-specific intelligence.

Every enterprise has years of proprietary history showing the context people had, the decisions they made, the actions they took, and the outcomes that followed. Ambral turns that history into intelligence that models can learn from.

Our systems are already deployed at multi-billion dollar enterprises across customer intelligence, account management, and other complex enterprise workflows.

Under the hood, we reconstruct historical company state and turn real work into replayable environments and automatically generated evals grounded in real workflows and outcomes. We use those evals to measure, compare, and improve models through post-training, context engineering, and agent engineering, building AI that gets better at the work unique to each company.

We're backed by YCombinator and other top investors and hiring exceptional builders and researchers.
