E-discovery giant Relativity is bringing on one of the tech industry’s most well-known investors as a new shareholder. But its CEO Mike Gamson says that while the investment will bring growth and scale, the company’s future still lies squarely within e-discovery.

Relativity announced Thursday that private-equity firm Silver Lake has become its largest shareholder with a significant minority stake in Relativity. The total dollar figure for the deal has not been announced, but The Wall Street Journal notes that the investment values Relativity at $3.6 billion. Previous investors ICONIQ Growth and company founder Andrew Sieja will remain as partners in the company.
