Envisage Equity LLC, which invests in middle market companies with big expansion plans, has invested an undisclosed amount in Baton Rouge-based Marucci Sports LLC, according to R2F Investment Bankers LLC.

R2F acted as a strategic adviser to Envisage on the investment in the bat and equipment maker.

Envisage takes both control and non-control positions in companies with roughly $3 million in earnings before income tax, depreciation and amortization, a measure of a company’s profitability.

The investment is the latest step in Marucci’s ambitious growth plan. In April, the company announced that co-founder Kurt Ainsworth had been named chief executive officer. He has laid out a blueprint for the company to double in size in the next two years and eventually become No. 1 in every product line for baseball.

Marucci, which made its reputation by providing high-quality wooden bats to Major League Baseball players, also announced plans to move into apparel with uniforms, sliding shorts and practice tops, and into the outdoor/hunting clothing market.

The privately held company’s growth has been financed, until now, from sales of its products and investments from a number of current and former professional baseball players.

To aid its growth strategy, Marucci added five new independent directors to its board: Ben Bordelon, chief operating officer of Bollinger Shipyards; Jim Burke, CEO of TXU Energy; Willie Robertson, CEO of Duck Commander; Jose Bautista, All-Star outfielder for the Toronto Blue Jays; and Ryan Stromsborg, co-founder and managing partner of Parq Advisors.
