The hardest part of doing good is knowing how much of it works.
Prova helps the people who fund and run social programs find out how well the work is going, for a fraction of what proof costs today, without lowering the bar.

See how →Foundations
Decision-grade evidence across the whole portfolio, not only the grants big enough to evaluate.
See how →Public sector
Robust, independent evidence on the timeline a decision actually runs on.

Proof comes in grades, and the price of reaching each is starting to fall.
The judgment stays human.
Whether an effect is real, and what it means here, stays with the people who decide.
Reaching any grade of evidence has always come down to one slow, costly step: skilled people reading the mountains of material a program produces. AI can now do much of that reading, carefully and under human supervision, so the same grade of evidence can be reached for far less. The judgment that decides what it means stays with people.
The Prova Method
One method, made explicit.
The standards behind the work are written down: how we match a claim to the strength of its evidence, how we find a credible natural experiment, how we stress-test a design before it runs. We hold our own claims to the same standard.
How to start · The Reads
Start with a Read.
A short, bounded diagnostic, and the lowest-risk way to see how Prova works. When a program is already running and needs measurement built in for the long term, that is Field.
The Counterfactual Hunt
Find the natural experiments already hiding in your data.
The Evidence Map
Match every impact claim to the grade of evidence beneath it.
The Pre-Mortem
Find what will sink a study before you commit to it.
Why Prova
Where Prova comes from.
Fifteen years building measurement into social programs, and then inside government, kept pointing to the same constraint. The will to know was there, and the methods were sound. What stood in the way was the cost of proof, in both money and time, and that is the one thing that can finally change.
