Our purpose
TrueRoll helps the assessment community do its work — easier.
TrueRoll's story begins with its founders.
Tyler Masterson, a strategic advisor at the time, and Joe Walsh, a data scientist, spent years working in the public sector and wanted to start a business that improved the government's ability to deliver services to its constituents. Seeing outdated tax rolls and infrequent audits costing governments millions, they envisioned a way to automate homestead administration. Automation could ease hardworking assessors' workloads, ensure eligible taxpayers receive tax benefits, and identify ineligibilities to transform how governments manage their homestead administration.
Looking ahead
Today, TrueRoll builds AI-powered automation for county assessor offices. What started as a single-purpose homestead monitoring tool has grown into a connected workflow platform, serving 150+ government offices across 10+ states. The mission remains the same. Bring this technology to tax offices everywhere to boost compliance, protect revenue, uncover unclaimed exemptions, and save assessors valuable time.
