The story
Founded in 2013 as a data-driven DTC lingerie brand, ThirdLove disrupted the intimate apparel market with inclusive sizing and technology-powered fit discovery. After scaling via direct online sales and raising $98.6M in venture funding, the company shifted from pure growth to profitability focus, taking on revolving credit in 2023 rather than additional equity. The embedded finance footprint is minimal — the company uses third-party tools for 401(k) benefits (Betterment at Work) and runs its e-commerce stack on Shopify Plus with NetSuite as its ERP backbone.
