Zeffy

More power to the people changing the world.

Nonprofits have an immense impact: they feed communities, protect the planet, educate children, and fight for justice — but their tools are holding them back. That’s why we’re building the global tech infrastructure to help them reach their full potential.

⚡ Today, 100,000+ nonprofits use Zeffy worldwide, with more than 10 million people relying on it. Together, they’ve raised over $2B — and every dollar goes directly to their cause.

Tech talent, driven by a shared mission

We hire selectively—only strong profiles—with high expectations and a lot of autonomy. Everyone here is hands-on, with near-unlimited resources to build fast and maximize impact.

We’re a passionate, highly committed team—engineers, ops, designers, and more. From startup founders to early team members in top tech companies, we all share the same drive: working for real-world causes that matter. Outside of work, you’ll find us cooking, doing yoga, spending time with friends — and logging a fair share of runs on Strava.

If this resonates, we’d love to meet you!
