Berkeley, California-based LeadGenius has closed a Series B financing round of $10 million. Lumia Capital led the financing, with participation from Javelin Venture Partners, and existing investor Sierra Ventures.

All other existing investors including Better Ventures, Bee Partners, Y Combinator (through its Continuity Fund), Kapor Capital, Initialized Capital, Fuel Capital, Scrum Ventures and FundersClub also participated in the round.

With this investment, Martin Gedalin of Lumia Capital has joined the LeadGenius board of directors. Noah Doyle from Javelin Venture Partners will join as a board observer.

LeadGenius says it uses a combination of machine learning technology and human researchers to gather and quality-assure B2B contact data. Marketers can also use LeadGenius’ SaaS platform to send out automated, personalized emails. LeadGenius is used by Google, eBay, Box, and Weebly.

A Y Combinator alum from the Summer 2011 class, LeadGenius has now raised more than $20 million in total funding.
