Who we are

Paris 🇫🇷 (EUR 75,000 to EUR 90,000) + stock options 💰 8+ years experience 🧪

🌬 Zeffy is leading a transformation in the social economy with its unique zero-fee fundraising platform, currently trusted by over 50,000 nonprofits throughout North America.

🚀 Experiencing a 300% year-over-year growth, we’re just getting started! There’s no better time to join us, as you’ll be among the first 40 employees set to make a tangible impact from day one.

🌱 If that’s not compelling enough for you, we are also proud to hold a B Corp certification.

Why Product Design matters

As Zeffy is entirely product-led (we have no sales), user experience is key to our growth:

• Self-serve activation: Over 10,000 new accounts created by organizations every month. Every step matters.

• Conversion on payment forms: With 500,000 monthly visitors and $60M processed monthly, better design directly means more funds for nonprofits.

• Revenue model: Entirely based on voluntary contributions. Exceptional design can completely change the game.

• Product Led Adoption: To maximize our impact, the product must remain simple and intuitive, even as it grows more powerful and feature-rich—a true design challenge.
