HaystackID has been aggressive in the e-discovery M&A market in recent years, with acquisitions such as eTERA ConsultingInspired Review and Envision Discovery. Now, the services provider is looking to expand further into the corporate market, announcing Tuesday a merger with NightOwl Discovery.

Through merging the two companies, NightOwl's managed services and proprietary technology will come under HaystackID's banner. NightOwl's leadership will join with HaystackID, including former CEO Andrea Wallack, who will become president of the combined company. NightOwl branding will also be transitioned to HaystackID following an integration period, but HaystackID said in a release that it expects no further changes for current NightOwl customers.

Financial details for the transaction were not released, though the press release announcing the deal notes that it was facilitated through Quad-C Management, who announced funding for HaystackID in February.
