Software-focused private equity house Thoma Bravo has bought into digital forensics solutions provider Grayshift subject to the receipt of regulatory approvals.

Thoma Bravo is in the market raising its fifteen flagship fund. It has collected a $100m commitment from PennSERS and up to $150m from the Texas County & District Retirement System in the past two months.

It also secured $45m from Maine Public Employees Retirement System last week for Discover Fund IV. The fund, which closed above target on $5bn last month, is focused on smaller investments than the firm’s main vehicle.

The firm raised $3.9bn for its third Discover Fund in late 2020, at the same time as closing Fund XIV on $17.8bn.
