Preregister a pilot
Whenever you're ready, the preregistration window is open. Commit to a design before data collection; we publish whatever you find.
Public preregistration is what separates evidence from after-the-fact rationalization. The form takes about 15 minutes; we review within a week and publish accepted preregistrations at /preregistrations/[id] with full design transparency.
Looking for funding?
The funders directory lists 21 foundations, agencies, and programs that pay for civic-experiment design and evaluation.
Most cities that don't pilot say the obstacle is budget, not capacity. Browse the funders directory for matching grant programs, or contact us — we help pilot teams identify and approach funders as part of our partnership work.
