Curtsy

Curtsy is a mobile-first, peer-to-peer resale marketplace where Gen Z and young millennial women buy and sell secondhand clothing, shoes and accessories. Founded in 2016 and originally a dress-rental service, it pivoted to resale and built its edge around making listing fast for casual sellers - using machine learning to suggest prices, fill in item details and estimate shipping weight, backed by human review. Sellers keep more of their money than on rival platforms (a ~19-20% commission), buyers save up to 70% on brands like Lululemon, Free People and SKIMS, and the app carries a 4.8-star rating across tens of thousands of reviews. Curtsy raised an $11M Series A led by Index Ventures in January 2021, part of $14.5M total funding.

Thatch

Thatch is a San Francisco health benefits platform that lets employers give workers a tax-free monthly healthcare budget instead of a one-size-fits-all group plan.

Built around ICHRA - a 2020-era IRS rule - the company aims to unbundle health insurance from a single employer plan and hand the choice back to individuals. Since launching in 2023 it has served more than 1,000 businesses and raised about $84.5 million across seed, Series A and Series B rounds.
