We're truly grateful that so many people have Foundant on their radar — it means a lot that our work resonates with others. That said, due to the high volume of direct messages and emails we receive, cold outreach isn't the preferred way to be considered for a role, and we're not able to prioritize applications submitted this way.

At Foundant, we build mission-critical software for the social good ecosystem — helping foundations, grantmakers, nonprofits, and community organizations streamline their work, strengthen relationships, and maximize their impact. We serve the giving community worldwide with a comprehensive suite of solutions spanning grant management, community foundation software, and giving analytics.

We're a unified company shaped by strong roots across our product portfolio, and we operate with intention and purpose. Our team of ~350 people across six countries is connected by a shared North Star: to be the trusted partner and strategic advisor to the communities we serve.

• Other duties as assigned.
