Union Square Ventures and Spark Capital have invested in stealthy company called Work Market that allows business to manage their labor and services. Neither fund disclosed the size of the round.

The company’s site is delightfully spartan right now, except for listing job openings for MySQL and Java developers. Work Market was founded by Jeff Leventhal, who previously founded a company for on-site services, such as computer, repair called OnForce.

Union Square’s Principal Fred Wilson joins the board and writes:

Jeff has been working in this sector for the better part of twenty years and Work Market is his fourth startup. We love working with serial entrepreneurs with a deep passion for a particular domain. That’s Jeff and his passion is bringing transparency and efficiency to work markets.

Work Market is expanding their team and is looking for A+ development and product management talent (Java and PHP) in the Greater New York area; click here to see the company’s job openings.
