Who Built This and Why It Matters

Tax Appeal Plus was created by Erik Wind, a real estate tech entrepreneur with over 25 years of experience designing and building software that solves real, operational problems for professionals in the property tax space.

Before launching Tax Appeal Plus, Erik joined GeoData Plus as its second employee in 2002 and acquired the company in 2012. Under Erik’s leadership, GeoData Plus became a household name among property tax professionals, agents, brokers, investors and lenders across New York and beyond. GeoData Plus was acquired in 2021 by ATTOM Data Solutions, one of the largest property data firms in the country.

Even while leading GeoData Plus, Erik was building something else — a passion project called Tax Appeal Plus.

Tax Appeal Plus is more than just another tool — it’s the result of two decades in the trenches, working alongside the firms that actually file appeals, manage cases, deal with municipalities, and juggle thousands of deadlines. Erik didn’t just consult on these problems — he personally designed and built the database and core engine that powers the platform today.

Unlike most real estate tech software built by outsourced developers or generic SaaS companies, Tax Appeal Plus was built by someone who understands both the domain and the code — and it shows.

Why I Built This

After selling GeoData Plus, I consulted with firms around the country. The feedback was almost always the same:

  • We’re drowning in spreadsheets.

  • Our current system doesn’t integrate with tax assessor data.

  • The software provider doesn’t understand our business.

  • We’re spending way too much time on things that should be automated.

So I built Tax Appeal Plus — from the database schema to the user interface — myself. It's lean, powerful, and designed specifically for companies that deal with hundreds or thousands of tax appeal cases each year.
