Columna is selling its majority stake in MSA Mizar, a tech-enabled insurance claims management provider, to private equity firm TowerBrook Capital Partners. The deal, announced via PE Hub, marks a significant exit for Columna, which acquired the business in 2019. Financial terms were not disclosed.

This transaction reflects the ongoing consolidation in the insurtech sector, where specialized service providers are attracting private equity capital. TowerBrook's investment suggests confidence in MSA Mizar's platform, which handles claims from first notice of loss to final settlement. For Columna, the sale provides liquidity and returns focus to its other portfolio companies.

The acquisition gives TowerBrook a foothold in the growing market for outsourced insurance operations. Insurers increasingly seek partners to manage claims efficiently, a trend accelerated by digital transformation. Watch for how TowerBrook plans to scale MSA Mizar's technology and client base post-acquisition, potentially through further add-on deals.
