FORTUNE — Jason Matlof has quietly stepped down as a partner with Battery Ventures, Fortune has learned.

He had joined the firm’s Silicon Valley office in early 2005 to focus on greentech and enterprise infrastructure investments. No specifics yet on his destination, except that it is expected to be an operating role (he had been VP of marketing and biz dev with Neoteris prior to joining Battery).

Matlof’s portfolio companies had included Clean Urban Energy, FirstFuel Software, Redwood Systems, Qteros and SolarBridge Technologies.

Some of Matlof’s board seats will be assumed by Battery’s Tom Crotty. In general, this basically marks the end of Battery’s foray into greentech investing, as it is not planning to add anyone to replace Matlof.
