Founded by former civil servants.
Chartreuse AI was founded in 2024 by people who spent years drafting business cases and reviewing the ones that came in.
Our team has secured £1.3bn in funding from HM Treasury. GAIA encodes what we learned about why a case gets approved and why one gets sent back.
The tool
Source documents in, a structured draft out.
GAIA works through the appraisal step by step and shows the reasoning behind every figure.
