DENVER, CO — After years of development and refinement, a new digital platform is changing how homeowners approach property tax appeals. Assessorly, founded by longtime real estate appraiser and data analyst Martin Froehlich, is the first online service of its kind that enables homeowners to quickly determine if their properties are over assessed—and to file appeals affordably and efficiently.

The platform addresses two of the biggest obstacles in the appeals process: cost and complexity. Traditional methods often require either legal representation or extensive personal research. Assessorly automates this by analyzing publicly available data and comparable home sales using proprietary algorithms, producing professional valuation reports within minutes.

Here’s how it works: Users simply enter their address into the Assessorly search bar. Within seconds, they receive a data-backed summary indicating whether their property is fairly assessed or overtaxed. If a reduction is possible, Assessorly outlines the potential savings and offers to prepare and submit a formal appeal.

For most single-family homes, the service costs $250 and covers up to three years of appeals (two tax cycles), reaching back to 2023. Additional services and a subscription plan are also available for ongoing support in future tax cycles.

The platform was built with input from both real estate professionals and engineers. Froehlich, who spent years conceptualizing the model, credits the platform’s practical execution to Richard Miles, Assessorly’s Chief Technology Officer. “Richard translated a decade of ideas into a functional, accessible system,” Froehlich said. “What used to require technical skill and inaccessible data is now a seamless experience anyone can use.”

The Assessorly dashboard presents homeowners with a clear breakdown of how their property’s value was calculated, along with a library and resources to manage an appeal on your own. This transparency, Froehlich says, is critical in giving users both clarity and confidence.

Following its successful launch in Colorado, the company is preparing to expand operations into California, Texas, and New Jersey, states where rising property taxes and complex appeal systems continue to burden homeowners.

“Our goal is to empower everyday homeowners with tools that were once only available to a limited few,” Froehlich said. “With Assessorly, we're closing that gap.”
