Hg, a global private equity investor, is leading a further majority investment in legal technology company Litera, which it acquired in 2018 from the investment firm K1 Investment Management.

The terms of this new investment are not being disclosed.

In the two years since Hg acquired Litera, Litera has been on a trajectory of aggressive growth and expansion, making 12 acquisitions, gaining over 10 times the number of customers it had then, and trebling its workforce.

Today, Litera has more than 1,000 employees across 17 countries and serves over 15,000 customers, it says.

“The velocity and complexity of this expansion has been made possible by an incredible team at Litera combined with a fantastic relationship with Hg, whose knowledge and impressive network in legal tech has presented numerous opportunities for the business,” Avaneesh Marwaha, Litera CEO, said in announcing the investment. “We are delighted that Hg is committing further investment into the business to provide Litera even more firepower to enable us to continue this trajectory for many years to come.”
