Months after completing a recapitalization, e-discovery services group HaystackID announced its acquisition of Envision Discovery and Inspired Review.

The terms of the acquisition have not been disclosed, but the three companies will fall under the umbrella of a new private-equity backed entity called Haystack Holdings, the formation of which was announced along with the acquisitions. Operations and technologies from Envision will integrate into the HaystackID offering, while Inspired Review will continue functioning as a separate unit, with its headquarters remaining in New York. HaystackID operates out of Boston.
