Greg Waldorf, the former chief executive of Pasadena online matchmaker eHarmony, has been named CEO-in-residence of Accel Partners, a Silicon Valley venture firm.

Waldorf stepped down Jan. 19 from Santa Monica-based eHarmony, which is rumored to be preparing an initial public offering. He was a founding investor in eHarmony 11 years ago and served the last five years as chief executive.

At Palo Alto-based Accel, Waldorf will work with the firm’s current portfolio companies and scout new prospects. Accel has previously invested in Groupon, Real Networks, metroPCS and Trulia, a real estate startup where Waldorf was a board member. Accel did not say whether Waldorf would continue to be based in Southern California.

Chief Operating Officer Greg Steiner is running eHarmony while its board conducts a search for Waldorf’s replacement.
