Google Capital is leading a $100 million series D round of funding in Thumbtack, a service that is described as helping people “accomplish the personal projects that are central to their lives”.

Also contributing to the funding are past investors Tiger Global Management, Sequoia Capital, and Javelin Venture Partners. Thumbtack has raised a total of $150 million to date.

What Thumbtack actually does is introduce people to “qualified professionals” in over 700 categories throughout the U.S. to help them complete projects. Customers answer questions about their needs, and Thumbtack connects them with these professionals within hours.

“First and foremost, Thumbtack is a great product. As a consumer, it’s the best product I’ve ever used to hire local professionals. The bigger story, however, is the potential for small businesses: Thumbtack has a real opportunity to transform how local professionals find new customers,” said David Lawee, General Partner at Google Capital. “The Thumbtack team is highly impressive and the opportunity in front of them is enormous. We’re excited to be a part of it.”

“We were already a strong and well capitalized business, but David and Google Capital offer something truly special, and we couldn’t pass up the opportunity to work with them,” said Thumbtack CEO Marco Zappacosta. “David brings years of experience working to help small businesses market themselves online, and the Google Capital financing and partnership allows us to think even bigger and further expand our business.”

Thumbtack joins the following companies in Google Capital’s portfolio: SurveyMonkey, LendingClub, Renaissance Learning, Auction.com, Credit Karma, Freshdesk, and MapR.
