Sonya Brown leaves Summit for Norwest by Dan Primack @FortuneMagazine June 28, 2011, 7:38 PM EST E-mail Tweet Facebook Google Plus Linkedin Share icons Sonya Brown has joined Norwest Venture Partners, according to an email sent out earlier today. She will be a partner in the firm’s Palo Alto office, with a focus on growth equity investments. Brown previously spent nearly nine years in Boston with Summit Partners, most recently as a principal responsible for the firm’s investments in North American consumer and Internet companies. Her board seats included Aramsco, Central Security Group, Physicians Formula Holdings FACE , Snap Fitness and Sparta Systems. Brown’s move comes just weeks after Mood Rowghani stepped down as a vice president with Summit, in order to join Kleiner Perkins. The firm currently is raising both a private equity and a venture capital fund, and finding the latter process much smoother than the former. Norwest is investing out of a $1.2 billion fund closed in 2009.
