Celerity Pro

Originally a part of Innovisk Capital Partners (“Innovisk”), Celerity Pro was founded in 2018 by current Celerity Risk Co-President, Carl Pursiano, to provide insurance solutions for small to mid-sized entities across the U.S. With the desire to provide simple solutions to complex business needs, while featuring a tech-based underwriting process shaped by decades of expertise, Celerity Pro offered management liability, professional liability, and cyber products on their Insurtech platform, Risk X. In 2025, after Ryan Specialty Underwriting Managers (“RSUM”) acquired Innovisk, Celerity Pro’s operations were merged with those of CorRisk Solutions, an RSUM-owned MGU, who also specialized in management and professional liability products.

CoRisk Solutions

CorRisk Solutions (“CorRisk”) was established in 2003 by current Celerity Risk Co-President, Tom Nash, to provide professional liability solutions for small to mid-market entities. Twenty year later, in 2023, after serving as the Professional Liability division of WKFC, CorRisk became the wholesale distribution arm of Ryan Financial Lines (“RFL”), a newly created division that encompassed the global management & professional liability MGUs of Ryan Specialty Underwriting Managers (“RSUM”). While solely responsible for overseeing RFL’s U.S. wholesale relationships, CorRisk consisted of various “practices,” which included Architects, Engineers & Contractors; Miscellaneous Professional Liability; Associations; Insurance Agents & Brokers; School Leaders; Media Liability; Management Liability, and Cyber Liability. After RSUM acquired Innovisk Capital Partners (“Innovisk”) in 2025, CorRisk merged with Innovisk’s MGU Celerity Pro, who also serviced the small to mid-sized management and professional liability markets.
