Sigma nets $500M

Sigma Partners has closed its eighth fund with $500 million in capital commitments. Don’t expect any major changes at the bi-coastal VC firm, which plans to continue investing mostly in early stage tech companies, plus a few deals in alternative energy.

“We do some consumer-facing Internet investments, but most of our tech focus is on things like semiconductors and software,” says Managing Director Greg Gretsch.

Gretsch says that the firm is no longer adding new portfolio companies to its $400 million seventh fund, which closed in 2005, and that it has already made its first deal out of Sigma 8.

All of the Sigma 7 partners are back for Sigma 8, except for the retiring Larry Finch, who is listed as a special limited partner. Sigma will maintain its dual offices in Boston and Menlo Park, Calif. The firm typically invests between $5 million and $7 million in early stage IT businesses.

Sigma was founded in 1984 by Burgess Jamieson and Brad Jeffries. —Dan Primack
