Jon Costello

I help companies win in Florida's government technology and procurement market, and I write about the people moving it.

Senior Florida political operator, co-founder of GovMastery, and consultant under Capitol Strategy Group. Each week I publish The Costello Brief, the intelligence I wish landed in my own inbox.

About

Operator first, writer second.

Jon Costello has spent his career in the rooms where Florida government technology and procurement decisions actually get made. He advises companies selling into the state and local market, reads the politics behind the buying, and knows the agency leaders, lobbyists, and vendors who set the pace.

He is the co-founder of GovMastery, which helps vendors understand and win the national SLED market, and consults under Capitol Strategy Group in Tallahassee. The Costello Brief is where he puts the weekly read on paper: who moved, what is being bought, and what it means.
