Economic analysis, accelerated
Economic evidence at the speed of policy.
Chartreuse AI pairs frontier AI with qualified economists to draft legislation-grade impact assessments in days. Public sector leaders use our work to make the case for funding and act on the evidence with confidence.
Our services
Three ways we turn analysis into outcomes.
02
Software That Works With Your Economists
The platform takes the weeks of drafting off your team's plate while your economists stay in charge of the assumptions and sign off the figures. When you want a second opinion, our experts are on hand.
03
No-Win, No-Fee Funding Applications
We build the economic case for central or local government funding bids. You pay only if the bid succeeds, so we carry the risk rather than your budget.
