Your Impact

The Altruist Accelerator: a supportive community of nonprofit leaders, staff, volunteers and changemakers who are ambitious to grow their organization’s impact.

How is the Altruist Nonprofit Accelerator unique? 

While our program is inspired by the most successful business
accelerators, the Altruist Nonprofit Accelerator:

  1. helps you solve the unique governance, program and revenue challenges of 501(C)3 organizations;
  2. helps nonprofits of all sizes and stages of maturity, not just startups; and
  3. accepts nonprofits of all mission types, including social justice, the arts, education, health, human services, environment, and others. 

What is an accelerator?

There are hundreds of business accelerators in the private sector, but no more than a handful in the social sector. Read this for a short overview of the space, and see Y Combinator for one of the first and most successful.
