FOR IMMEDIATE RELEASE  
Ascendex Underwriters Sets a New Standard in Specialty Underwriting

Backed by Altamont Capital Partners, Ascendex Underwriters empowers its underwriting practices through innovative technology, AI-powered risk selection and data integration delivering superior performance across the commercial specialty landscape.

NEW YORK, NY – September 9, 2025 — Ascendex Underwriters, a next-generation Managing  
General Underwriter (MGU), announced its formal launch today. The company introduces a  
model built for the future with underwriters as true owners, empowered by a unified, scalable  
platform that delivers market-ready execution from day one. This unique model, which provides  
smart execution built for growth and durability, sets a new standard in the specialty underwriting  
Industry.

Ascendex enables experienced underwriters to operate as true owners, helping to guide the  
organization and share in the equity upside of the entire business. Ascendex is a platform  
MGU, supported by a centralized tech stack, real-time risk intelligence, and institutional-grade  
compliance. The result: faster decisions, greater accountability, and scalable programs built on  
underwriting performance.

“Ascendex was built on a simple but powerful idea: the best underwriters deserve more  
than a seat at the table; they deserve the chance to build the table. We’ve created a  
platform where entrepreneurial talent can scale with autonomy, ownership, and the infrastructure to deliver sustainable underwriting results,” said Kevin Rehnberg, Co-Founder  
& CEO of Ascendex.

At the heart of Ascendex is a fundamental shift. Ascendex hires top-tier underwriters to run their  
P&L, scaling faster through a combination of technology, AI, and seamless submit-to-bind  
capabilities that include best-in-class partners, such as Federato for risk decision-making and  
Workday for enterprise operations. This approach instills confidence with carrier and brokers to  
partners alike, knowing that they are joining forces with an elite underwriting organization.  
A seasoned team of insurance professionals co-founded Ascendex, bringing decades of experience. The team, led by Kevin Rehnberg (Co-Founder & CEO), Andrée Bourgon (Co-  
Founder, COO & Head of Finance), Dan Grayzel (Co-Founder, Head of Corporate Development & Strategy), and Dawn Zoppa (Co-Founder, Head of Technology & Digital Solutions), brings a  
wealth of expertise in executive leadership, operational excellence, digital transformation, and  
growth strategy across the specialty insurance market.

“We backed Ascendex because of the combination of the structural innovation of its  
business model and the deep industry credibility the founders bring to the table,” said Sam  
Gaynor, Managing Director of Altamont Capital Partners. “This team represents the next  
generation of specialty underwriting leadership—disciplined, proven, and fully aligned with  
what capacity providers are demanding.”

Ascendex is actively onboarding its first wave of underwriting practices, each with deep  
underwriting expertise and established market relationships, with the first slate of select  
practices set to launch in the near term. These initial offerings reflect Ascendex’s focus on  
underwriting performance and specialty discipline, with additional practices in development.  
Partnering with a range of (re)insurance markets, Ascendex is rapidly building a portfolio of  
high-performing commercial specialty programs designed for sustainable growth.

“Ascendex was founded on the belief that the future of underwriting is intelligent infrastructure, empowered underwriters, and a relentless focus on innovation,” said Andrée Bourgon. “Ascendex is an AI insurtech built to rethink underwriting from the ground up with data, automation, and agility at the core of everything we do.”
