With Google as one of its big investors, Airbnb, the online marketplace that enables people to list, find, and rent vacation homes for a processing fee has raised $555 million at a $30 billion valuation, according to a new financial filing by the company. This fund is part of the total $850 million round that it announced to raise last month.

According to The Wall Street Journal, Google Capital and Technology Crossover Ventures led the deal. The report also mentioned a source who “confirmed that Airbnb plans to file a Form D with the Securities and Exchange Commission on Thursday with details of the raise, and that the round has not closed yet. Airbnb still plans to raise the total $850 million, the person said.”

The Journal also reported that Airbnb employees were able to sell some of their shares as part of the deal.  The company's current valuation makes it the second most valuable US startup behind Uber, which investors have valued at around $68 billion.
