Proofpoint Has Second Big Raise in Six Months: Total Funding Now Exceeds $100M

[Major update to this story, which I posted yesterday morning, 7/31. In a nutshell, it’s wrong; my apologies. Proofpoint told me soon after I’d posted that it was confused by what I’d seen, so I sent over the SEC Reg D filing relating to this funding. I didn’t hear back until just now, Friday morning, when Proofpoint told me that the filing pertains to its deal with Fortiva, a company it acquired early last month. The transaction was a cash-and-stock deal, and the $16.5M I wrote about below represents the shares given to Fortiva.]

Six-year-old Proopoint, a Sunnyvale, California, email security firm, is raising yet another $16.5 million in funding, according to a regulatory filing I just stumbled across while searching for something else.

The round comes just six months after a $28 million round raised in February, which either suggests the company is gearing up for something major, or it needed the capital to cover its purchase of Toronto-based Fortiva, an on-demand email archiving company that Proofpoint acquired earlier this month for an undisclosed amount.

Either way, the company has now raised $102.5 million over seven rounds. For what it’s worth, the $16.5 million has come from Benchmark Capital, Mohr David Ventures, Meritech Capital Partners, and RRE Ventures. Not returning from Proofpoint’s sixth round in February: Bridgescale Partners, JAFCO Ventures, or DAG Ventures.
