What Summersalt does

Summersalt is a direct-to-consumer women's apparel brand headquartered in Saint Louis, Missouri, founded in 2017 by Lori Coulter (Co-founder, CEO and President) and Reshma Chattaram Chamberlin (Founder and Chief Brand and Digital Officer). The company sells premium swimwear, cover-ups, clothing, pajamas, loungewear, and beach accessories exclusively through its owned e-commerce site, summersalt.com, shipping to customers in the United States, United Kingdom, Canada, Australia, and the United Arab Emirates via a multi-currency storefront (USD, GBP, EUR, AUD, AED). Its core customer is women seeking designer-quality swimwear and beachwear at accessible price points, with a particular emphasis on inclusive sizing (0-22/24) and fit segmentation across long-torso, plus-size, maternity, and family-swim categories.

The company's product platform is built on a proprietary signature compression fabric offering 4x the compression and 5x the strength of typical swimwear, engineered using a dataset of 1.5 million body measurements collected from 10,000 real women. This data-backed fit system underpins the flagship one-piece collection (most notably the trademarked Sidestroke), as well as wrap, cutout, and ruffle one-piece styles, a full bikini line, the Silky Luxe cover-up line, the Seersucker clothing collection, and limited-edition collaborations such as the Summersalt x Bridgerton capsule with Liberty Fabrics and the Summersalt x Weezie Americana collection. The brand has earned editorial placement in Travel + Leisure, InStyle, Forbes, the New York Times, Harper's Bazaar, and Oprah Daily, which functions as its primary earned-media engine in lieu of wholesale distribution.

Commercially, Summersalt operates a pure-play DTC model with one-time unit pricing (one-piece swimsuits $125-$155, bikini tops $65-$85, bikini bottoms $45-$70, cover-ups $59.95-$135, Seersucker clothing $75-$135), supported by seasonal promotional events such as the Heat Wave Sale. It has raised approximately $26.65 million across four disclosed funding rounds between June 2017 and December 2019, with Mercato Partners leading the most recent round and Founders Fund leading the prior round. The company runs marketing primarily through Instagram, Facebook, Pinterest, and email, with no disclosed wholesale, marketplace, or physical-retail presence.
