Catalyst Property Tax Consultants
How a Colorado tax-appeal practice broke through its own capacity ceiling
Catalyst Property Tax Consultants appeals commercial property assessments for Colorado property owners. Their three principals share a rare specialty: they know how to argue a property's value to a county Board of Equalization and win.
The hard part is timing. New commercial assessments come out once every two years, and owners get a narrow window to challenge them — so much of a two-year revenue cycle has to be earned in a few weeks. Catalyst met that crunch the old-fashioned way: temporary staff pulling data from county records, real estate databases, and client financials, then hand-assembling each 12-page appeal packet to a standard that could hold up under Board scrutiny. Done right, a single packet took five to eight hours.
Even at full speed, that capped the firm at roughly 400 cases per cycle. The bottleneck was never expertise — it was how many packets human hands could produce before the window closed.
We didn't set out to sell Catalyst a tool. We set out to learn how they work.
Our first weeks were spent alongside the three principals, watching real appeals come together — where the hours disappeared, where the judgment calls happened, where one small error could lose a case. What we built wasn't a generic "property tax app." It was a faithful reflection of Catalyst's own methodology: every formula, every report section, every rule about which data source to trust, modeled from how they already did the work. The technology served the method, never the other way around.
The real work happened in the iteration. Each week, the team ran the platform against live appeals.
Whenever a number didn't match what a principal would compute by hand, that discrepancy became a permanent rule. More than a hundred judgment calls once locked in the principals' heads are now enforced automatically, so every packet — principal-made or produced by a seasonal analyst — holds to the same standard.
As trust in the platform grew, so did its reach. What began as a packet generator for one county is now a working platform across six Colorado counties — Adams, Boulder, Broomfield, Denver, Jefferson, and Weld — with more than 1.3 million rows of reconciled data from assessors, commercial databases, and Catalyst's own client history, all searchable from one dashboard.
A packet that once took five to eight hours now comes together in roughly thirty seconds — delivered in the same polished form the firm used to produce by hand.
When the next biennial assessment cycle opens in 2027, a practice that historically topped out near 400 appeals is positioned to handle thousands. The old ceiling, set by how fast temporary staff could assemble packets, is gone; the only limit now is the market itself. Every figure still traces to a known source, every override is logged, and every principle Catalyst appeals by is something the software now protects — so the firm can scale without diluting what its clients pay for.
Blue Fractal didn't just show up with a product; they showed up ready to learn and understand our business, and they built a tool that thinks about the work the way we do. Throughout, they've been a diligent partner listening to every request and building each adjustment into a rule the platform now honors.Jason Flynn — President, Catalyst Property Tax Consultants
