SF local services marketplace with 80M+ consumers and 250K+ pros across 1,000+ categories; $500M Sequoia/Tiger Global-backed shifting to pro subscription model competing with Angi and TaskRabbit for US home services marketplace.
Thumbtack is a San Francisco-based online marketplace for local home and professional services — backed by approximately $500 million in total funding from Sequoia Capital, Tiger Global, Google Capital, and Baillie Gifford — connecting 80+ million consumers with local professionals across home improvement (contractors, plumbers, electricians, painters, landscapers), events (photographers, DJs, caterers, florists), lessons (music, tutoring, fitness, language), and wellness (massage therapists, personal trainers, nutrition coaches) in 1,000+ service categories across the United States. Founded in 2008 by Marco Zappacosta, Sander Daniels, Jonathan Swanson, and Jeremy Tunnell, Thumbtack has shifted its business model from a marketplace where pros pay per lead to a subscription-based model (Thumbtack Pro Membership) where professionals pay monthly fees for profile promotion and customer connection tools.
