We are excited to partner with THL, a firm with a proven track record in both insurance and technology and deep experience in helping companies accelerate growth through providing exceptional service. THL will support us in realising our vision to support a greater portion of our customers' complex technology needs as we strive to become a top 5 global technology vendor."

Brizius, Managing Director at Thomas H. Lee Partners.
