Additional Information
About On Me Humans have given each other gifts since the dawn of time. For gratitude, for friendship, and for love. In today's society, gifting has become harder and much more wasteful, as it's become nearly impossible to know exactly what someone wants, when you just want to show that you care. On Me is revolutionizing gifting by rebuilding it for the mobile and Instagram era. Traditional gift cards are impersonal and rigid, usually sold by an old and wealthy megacorp. We make it easy to send a personalized, media-rich gift that's spendable across brands, fits someone's hobbies, and drops straight into their mobile wallet for tap‑to‑pay. Check out our live experience at onme.com . We're a small startup from Google and Apple moving fast on a massive category and have raised $8M from top‑tier investors like NFX, Lerer Hippeau, Focal VC, and Mastercard . Since launching in November 2024, On Me has been featured in Tech Crunch, Fortune, and The Wall Street Journal. In 2025, we sustained over 40% growth month over month throughout the year, and the trend shows no sign of stopping. In 2026, we're doubling down on making every gift feel magical end‑to‑end and building an amazing consumer product. You'll help us build a world-class web platform and mobile apps that people love. If you want meaningful ownership, clear consumer product impact, and the chance to set engineering standards early, this is it.
