Company Overview
About ThirdLove
ThirdLove is a data-driven direct-to-consumer intimate apparel brand founded in 2013 by Heidi Zak and David Spector, headquartered in San Francisco, California. The company disrupted the bra industry by introducing half-cup sizing — going far beyond the limited size range of traditional lingerie brands — and now offers bras in 78 sizes, catering to a broad spectrum of body types with a focus on precision fit and comfort. ThirdLove built its sizing system and product line using data collected from more than 18 million women who completed its Fit Finder quiz, creating proprietary insights into consumer fit needs that fuel ongoing product innovation.
Business Model & Competitive Advantage
ThirdLove generated approximately $69M in 2024 revenue with a repeat customer rate of approximately 60% — significantly above the 20–30% typical of e-commerce — reflecting strong brand loyalty and high product satisfaction. The company has approximately 160 employees and has expanded its distribution beyond its DTC website to Neiman Marcus store locations and Amazon. In 2025, ThirdLove launched its TempSync bra with temperature-regulating fabric technology and expanded its menopause-focused line into activewear, targeting underserved consumer segments with high margin potential. The company is exploring maternity and post-surgical categories as adjacent growth opportunities.
Competitive Landscape 2025–2026
ThirdLove's approach to social responsibility includes donation programs that provide bras to women in need and in-store recycling initiatives for worn-out intimates. The brand competes with Victoria's Secret, Savage X Fenty, Aerie, and direct-to-consumer entrants, but holds a defensible position through its proprietary fit data, inclusive sizing infrastructure, and loyal customer base built over a decade of DTC engagement.
