Venture capitalists were active in the e-discovery field this week, with FTV Capital pouring $32 million into Catalyst Repository Systems, and Sequoia Capital hiring former Clearwell Systems CEO Aaref Hilaly.

The news is just the latest in industry growth this year, following an active 2011 on the mergers and acquisitions front. So far in 2012, Epiq Systems bought De Novo Legal for $68 million, LexisNexis sold Applied Discovery to Siris Capital, Symantec bought LiveOffice for $115 million, and Guidance Software acquired CaseCentral in a $17 million deal that could expand to $50 million.
