While companies like Betterment are using technology in an attempt to break into and expand the 401(k) space, a robo-advisory pioneer is moving in the other direction by trying to humanize its 401(k) services.

Sunnyvale, Calif.-based Financial Engines, sometimes called the first robo-advisor, has announced that it will purchase Overland Park, Kan.-based RIA The Mutual Fund Store for $560 million.

Financial Engines President and CEO Lawrence Raffone said that his company intends to use The Mutual Fund Store’s 200 advisors to expand services to investors in 401(k) plans and provide more face-to-face interaction for their clients.

“By leveraging Financial Engines’ scalable advice technology to power The Mutual Fund Store’s services and in-person advisors, we believe we will be able to make high-quality investment advice and comprehensive financial planning available to everyone with access to our services through their employer,” Raffone said. “This acquisition advances our vision to provide independent advisory services to more people and we believe will also fuel significant future growth.”

Next year, Financial Engines plans to launch a service providing 401(k) plan participants access to human advisors.

The deal involves cash and shares of Financial Engines, which is publicly traded, and makes Warburg Pincus, currently The Mutual Fund Store’s principal owner, the largest shareholder of Financial Engines.

As part of the deal, Warburg Pincus will receive $250 million in cash and 10 million shares of financial engines, or 12.5% of the company. Michael Martin, the managing director of Warburg Pincus, will be appointed to Financial Engines’ board of directors.

The Mutual Fund Store was founded in 1996 in Overland Park by Kansas City-based advisor Adam Bold. While it started as a franchisor, the company has grown to 129 locations and 345 employees nationally. The firm invests nearly $10 billion on behalf of 39,000 clients.

As of September 30, Financial Engines had 520 employees providing services to 9.4 million clients and managing nearly $108 billion in client assets.

The companies expect to complete the sale in early 2016.
