Brands born on the internet are coming of age, and Santa Monica-based investment mergers and acquisitions advisory firm Sage Group wants to help them get to the next level.

Sage Group has established a dedicated ecommerce practice to take advantage of a growing wave of “disrupting transactions” over the past 18 months, according to the chief banker in charge of the new unit.

“The ones attracting the most M&A interest have a strong grip on an attractive demographic, demonstrate a compelling lifetime value progression over a multiyear period and have meaningful offline potential,” said Sage Group’s senior banker Andrew Dunst in an interview with the Business Journal.

Sage formed the practice after providing advisory services to New York City-based sock manufacturer Bombas in its sale to Boston-based private equity firm Great Hill Partners; La Jolla-based bracelet maker Pura Vida in its sale to Fort Wayne, Ind.-based luggage and handbag company Vera Bradley Inc.; and Burbank-based cosmetics and beauty products maker BH Cosmetics Inc. in its sale to New York City-based private equity firm MidOcean Partners.
