Catalis Expands Suite of Technology Solutions with Axiomatic Acquisition

The announcement comes fresh on the heels of Catalis’ recent rebrand.

Alpharetta, GA, September 19, 2022 – Catalis, one of North America’s leading government Software as a Service (SaaS) and integrated payments providers, is growing. Today Catalis announced it has acquired New Hampshire-based Axiomatic, a leading software provider that offers an array of web-based solutions and services throughout the United States for state property tax oversight and administration.

Catalis is a trusted technology partner for thousands of US and Canadian government entities. Its acquisition of Axiomatic is part of its commitment to continue offering clients innovative technology and a growing suite of solutions, including building its Computer Aided Mass Appraisal (CAMA) subject matter expertise and offering a state-focused solution.

“Catalis is thrilled to integrate Axiomatic’s solutions to automate the state property tax oversight process and to expand the valuation tools and workflow solutions we offer for end- users,” says John Kristel, CEO of Catalis. “Axiomatic’s state-level-focused tax oversight and administration solutions are a fantastic complement to Catalis’ existing product capabilities.”

Founded in 2013, Axiomatic is the industry leader in modernizing property tax oversight agencies, from processes to software and policy. Its flagship product, PropTax, automates property tax oversight for state agencies across all stages of the property tax cycle through its fully configurable suite of web applications. Its easy-to-use interfaces provide state property tax administrators with the tools, automated workflows, geospatial integrations, and analysis needed to increase both efficiency and accuracy.

“Catalis presented the perfect fit to the business and culture we have built over the past nine years,” says David Salzer, Co-Founder of Axiomatic. “Catalis shares Axiomatic’s traditions of excellent service, subject matter expertise, and a corporate ethos our clients and associates want to be a part of.”

In 2021, a recapitalization co-led by growth equity firm PSG and leading global alternative asset firm TPG boosted Catalis’ valuation to more than $1 billion. Catalis’ latest acquisition aligns with its ambitions for expansion as the premier software and digital payments provider for North American governments.

Late last month, Catalis announced a rebrand as part of the company’s natural progression. Catalis’ existing CAMA providers will directly benefit from this acquisition by gaining a deeper understanding of state reporting needs and requirements. In turn, Catalis will be able to help its county and municipal-level customers streamline their data reporting to state oversight agencies.

“When we announced our rebrand, we assured our customers we would continue to provide incredible customer service and an expanded range of resources and solutions,” continues Kristel. “This acquisition is just the beginning.”
