Thumbtack has raised its second large round in three months, bringing in a fresh $100 million in a financing led by Google Capital. In May, the company raised $30 million at a valuation of over $230 million from Sequoia Capital and Tiger Global Management, both of which participated in the new round alongside Javelin Venture Partners. Thumbtack's online marketplace connects professionals with people looking for assistance with projects, events or tasks. It has listings in some 700 categories across all 50 U.S. states, sending an estimated $1.8 billion in business annually to more than 75,000 paying professionals. The funds raised in the last three months will be used to launch a U.S.-wide marketing campaign and scale engineering teams. Thumbtack has raised a total of $150 million since its launch in 2009.
