Financial Engines, a 401(k) investment advice-giver, has released a version of its advice software directly to participants in 401(k) plans. The company was marketing its software mainly to Fortune 500 companies that have 401(k) plans, said Jeff N. Maggioncalda, president and CEO. Now participants whose companies do not provide investment advice can purchase online advice, he said. Individuals who purchase the service will have to input their 401(k) plan and financial information, he said. Support will be offered by e-mail exchanges with Financial Engines representatives through visiting the companys online support center, Mr. Maggioncalda said. Telephone support will be available for an additional fee, he added. Separately, John Thibault joined Financial Engines as vice president of marketing. He will be in charge of product marketing, marketing communications and customer development. Before filling this new position at Financial Engines, he was vice president at eBay.
