Teespring was one of the hottest consumer internet startups of the 2010s. Graduating from Y Combinator's Winter 2013 cohort, the company raised over $60 million in venture funding, including a high-profile $35 million Series B led by Andreessen Horowitz partner Lars Dalgaard and Khosla Ventures at a peak valuation of over $400 million. After an initial expansion phase that burdened the company with heavy factory leases, leadership restructured operations to embrace an asset-light distributed manufacturing model. Rebranded as Spring and acquired by Amaze Software in 2022, the business disciplined its unit economics, expanded digital product sales, and accelerated annual revenue to $155 million in 2024, $170 million in 2025, and reached $185 million in fiscal year 2026.
