ShareBuiler is a United States online stock brokerage firm founded in 1996 (as NetStock Direct). It encourages recurring, automatic purchases of shares of stock and exchange-traded funds. All transactions occur online and are entirely at the discretion of the account holder, thus it is an execution-only service. The company does not have brokerage sales representatives or advisors. Account holders can use ShareBuilder's online research tools to investigate stocks, similar to other online brokerages such as TD Ameritrade and Fidelity. In 2005, ShareBuilder began offering 401K plans to small businesses. On November 19, 2007, ShareBuilder Corporation was purchased by ING Direct for $220 million USD.
