Venture capitalists are seeing dollar signs in legal technology—and they’re not just pouring money into industry newcomers. Vista Equity Partners has a history of investing in legal technology companies, most notably  Aderant and Mitratech. Recently, the company launched its Endeavor Fund, which focuses exclusively on enterprise software and data businesses under $30 million in revenue. And to kick off the fund, it has once again returned to the legal tech well.

On May 16, e-discovery company Zapproved announced that it has selected Vista Equity Partners for a strategic investment in the company, and Zapproved will become the first company in the new Endeavor Fund. Financial details of the investment were not disclosed.
