Resurgens Announces Sale of Castellan Solutions to Riskonnect, Backed by TA Associates and Thoma Bravo

ATLANTA & AUDUBON, Pa.–(BUSINESS WIRE)–Resurgens Technology Partners, a software-focused private equity firm, is pleased to announce the sale of its portfolio company Castellan Solutions, a global provider of enterprise resilience management solutions, to Riskonnect. Backed by TA Associates and Thoma Bravo, Riskonnect is a leading provider of integrated risk management software solutions that enable organizations to anticipate, manage and respond in real time to strategic and operational risks across the company.

The combined company will deliver increased value to customers across the entire risk spectrum, including business continuity and operational resiliency solutions, as well as integrated risk management product capabilities, global support infrastructure and expertise in-depth in the multisectoral field.

“With the Resurgens partnership, Castellan has become a truly innovative platform to reduce risk, improve resilience and better manage business continuity,” said Jon Ezrine, CEO of Castellan. “Today’s step demonstrates how we have applied innovation and investment to help our clients assess and manage operational risk and build resilience in their organizations. Resurgens has been instrumental in our recent growth and success, and we look forward to the next chapter with Riskonnect.

In 2018, Resurgens made its initial investment in Assurance Software (now known as Castellan) as a carve-out of Sungard Availability Services. Since then, Resurgens has played a vital role in providing the resources, investment and guidance necessary for the company to thrive as an independent business, helping to foster excellence in talent, operations and mergers and acquisitions. Resurgens worked with Castellan’s management team to complete two subsequent acquisitions, which allowed the company to expand its geographic reach and deliver a fully integrated, end-to-end operational resiliency solution that spans software, consulting and managed services. Resurgens will continue to be an investor in the combined company.

“Integrated risk management is becoming increasingly mission critical for all types and sizes of businesses, and Castellan’s suite of products enables customers to strengthen organizational preparedness and response capabilities to minimize disruptions,” said Fred Sturgis, chief executive of Resurgens. “We are very pleased, on behalf of Castellan, to be part of Riskonnect as they continue to expand globally and invest in new opportunities. »

Shea & Company and Baird served as financial advisors to Castellan.
