The problem

Why answers about your city take too long.

Cities publish an enormous amount of information — but it's scattered across departments, buried in PDFs, and published without the context needed to make sense of it. Finding one real answer often means opening ten systems and reconciling records that don't agree. The data was never the hard part. Understanding it was.

Why Alkartis

Built to be trusted before you've even read the data.

Not a dataset. A decision.

Nobody wants ten million rows. They want to know if a raise is unusual, an assessment is overvalued, or a department is growing faster than the rest of the city.

One connected layer

Payroll, assessments, and permits aren't separate stories — they're related signals. Alkartis links them so a change in one shows up everywhere it matters.

Traceable, always

Every number traces back to its public source. No black boxes, no unexplained scores — just data made legible.

Flagship application

Our belief

Data informs. Context explains. Intelligence empowers.

Data alone isn't intelligence. Neither is a chart. Neither is AI. Information has to be connected before it becomes useful — that's the whole philosophy behind everything we build.

ALKARTIS
Founder, Alkartis
Philadelphia, PA

Years inside one of the largest municipal governments in the country revealed the real barrier: not missing data, but information scattered across systems with no context to make sense of it. Alkartis exists to close that gap.

Our vision

In time, people won't say "I used a data tool."
They'll say "I asked Alkartis."
