This approach instills confidence with carrier and brokers to partners alike, knowing that they are joining forces with an elite underwriting organization.

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.
