The Vistria Group, LP, a middle-market private investment firm with deep experience across essential and regulated industries, has acquired Lumen Holdings, LLC, a Dallas-based technology-enabled Managing General Agent (MGA). The transaction establishes Lumen as a new platform investment within Vistria’s Financial Services strategy and marks a significant step in the firm’s multi-year focus on the evolution of the specialty MGA market.
As carriers increasingly seek specialized underwriting partners with strong distribution networks and digital infrastructure, specialty MGAs have become an essential part of the insurance ecosystem. Vistria’s investment reflects its conviction that technology-driven underwriting platforms are well positioned to capture growth in a market demanding precision, speed, and disciplined performance.
Founded in 2019, Lumen has quickly built a diversified underwriting platform spanning commercial property, builders’ risk, commercial general liability, personal auto, homeowners, and umbrella coverage across more than 30 states. The company has developed a broad network of wholesale and retail distribution partners while successfully launching and scaling multiple de novo programs. Its consistent underwriting performance has earned support from leading capacity providers, reinforcing its position in a competitive and highly regulated market.

At the center of Lumen’s operating model is KURRENT, its proprietary digital underwriting and distribution platform. The system integrates submission intake, underwriting communication, policy issuance, endorsement processing, renewals, and real-time portfolio analytics into a unified dashboard. By embedding analytics and automation into core workflows, KURRENT enables Lumen to scale efficiently while maintaining underwriting discipline. The company recently enhanced the platform with expanded digital capabilities tailored to personal lines, modernizing infrastructure within a traditionally fragmented segment of the insurance industry.
Scott Whitaker, Founder and Chief Executive Officer of Lumen, described the partnership as a natural alignment of vision and strategy. He noted that Vistria’s belief in the long-term value of specialty MGAs mirrors Lumen’s commitment to building a best-in-class, diversified underwriting platform powered by advanced technology. With Vistria’s support, Lumen plans to accelerate talent recruitment and expand new program launches through the KURRENT platform.
From Vistria’s perspective, the investment fits squarely within its broader Financial Services thesis. Boris Rapoport, Senior Partner and Co-Head of Financial Services, emphasized that expertise, infrastructure, and data-driven underwriting are becoming critical differentiators in regulated markets. He highlighted Lumen as a clear example of the type of focused, technology-enabled partner carriers increasingly rely upon.
Mike Castleforte, Senior Partner and Co-Head of Financial Services at Vistria, added that Lumen’s combination of underwriting rigor, proprietary technology, and diversified distribution creates a strong platform for continued expansion. The firm views the specialty MGA segment as structurally attractive, particularly as carriers outsource specialized risk selection to partners with disciplined processes and scalable systems.
