There are some big new names backing ZocDoc, a start-up that lets you book doctor's appointments online (currently just in New York). Salesforce CEO Marc Benioff has contributed an undisclosed amount to the company, as has Bezos Expeditions, the investment firm run by Amazon.com founder Jeff Bezos.

In August, the company announced a $3 million Series A funding round led by Khosla Ventures, the firm created by Sun Microsystems founder Vinod Khosla. The Bezos and Benioff investments are considered contributions to that round.

The New York-based ZocDoc currently employs 12 people and said that there were nearly 20,000 medical appointments available for booking in the month of September.
