Leveraging its proven platform creation playbook and deep industry experience, Altamont has helped Accelerant scale its exchange from inception to more than $3.5 billion of gross written premium1 across 232 Members. The firm worked closely with the Accelerant team, including Co-Founder and CEO Jeff Radke, to hire the requisite talent and develop the systems and technology partnerships to support this growth, while, as the controlling shareholder, playing a key role in the company's strategic decisions over the last six-plus years.

"The expertise we have developed across the entire insurance value chain enabled us to recognize the true differentiation in Accelerant's business model from the first meeting," said Sam Gaynor, Managing Director at Altamont. "And we're proud that our experience and relationships have been additive in helping Accelerant deliver the tremendous value it has to both the supply (specialty underwriters) and demand (risk capital) sides of its Exchange."

"The Accelerant partnership is a prime example of Altamont's strategy of transforming and scaling its portfolio companies," commented Keoni Schwartz, Co-Founder and Managing Director at Altamont. "We combine deep industry expertise with decades of experience driving fundamental growth in lower-middle-market businesses in order to drive outsized outcomes for both management and our investors, and our work with the Accelerant team to scale the company from a true start-up to an IPO is a terrific testament to that approach."

Both Keoni Schwartz and Sam Gaynor will retain board seats in support of Accelerant's continued growth and development.
