What is Summersalt?

Summersalt is a women's swimwear brand that sells directly to customers online, skipping wholesale middlemen. It was founded in St. Louis by Lori Coulter, its chief executive, and Reshma Chattaram Chamberlin, its chief brand officer.

History

The company launched around 2017. In 2018 it raised a 2 million dollar seed round followed by a 6 million dollar Series A led by Founders Fund.

Products and positioning

Summersalt designs its swimsuits in house and sources eco friendly fabrics directly from factories in the United States and Asia. Pricing at launch was set at 95 dollars or less per swimsuit. The brand planned to extend sizing up to 22 and to add a travel apparel line.

Fit is a central part of the proposition. The company holds a patent for recommending garments based on body type and consumer preference, drawing on more than 10,000 body scans and around 1.5 million measurements.

Why it matters

Summersalt is an example of a digitally native brand using body data to tackle fit in a category where sizing is a major source of returns.
