For public safety

Incident data lives in a records system that rarely meets the rest of the city's data. Polisynth joins it with everything else, so patterns show up by block and by month, and prevention programs can be judged on results.

Commitments Pilot

Sidereal

Holds every funded program to the result it promised.

Before money moves, each program gets a written commitment: the result, how it is measured, the starting point, the target and date, and who owns it. Sidereal tracks delivery and results against it.

Getting started

First
One department
A diagnostic built from public data: where the department's money goes compared with where the need is, the opportunities ranked, its program up for renewal evaluated and its public commitments tracked. Nothing is needed from the city to begin.
Then
The city's own records
The city adds its records and documents under its data-use agreement. Staff use Zenith and Meridian, and Sidereal tracks what was committed.
Then
Citywide
Every department on the same model, Parallax before new programs, and contracts that pay for results.
