How Summersalt built a swimwear brand from 10,000 body scans

Summersalt launched from a data set most brands would never attempt to build. The team scanned 10,000 women, made a swimsuit for each, and collected detailed feedback on fit. That pattern library still drives the product engine today, and swimwear brands that earn that trust historically hold 80% of wallet share going forward.

Lori Coulter, Co-Founder and CEO of Summersalt, tells Bryan how she and her co-founder went from a Chipotle lunch to a top 1% launch in under a year, why she still participates in every fitting, and where AI is actually delivering returns at Summersalt today.
