Nonprofit Builder is home to a community of 942 consultants from all over the world, all specialized in working with nonprofits. Together, we serve 1,202 organizations supported by 48 leading foundations. We're always looking for exceptional people to join.
Experienced professionals who've made nonprofits their focus
The consultants who thrive with Nonprofit Builder share a few important qualities.
Deep commitment to the nonprofit sector. Nonprofits are your main focus. Some of our consultants work part-time with businesses, but their passion and expertise lie in helping nonprofits grow stronger, more strategic and more resilient.
Real availability. Most of our consultants work independently or lead small practices. We look for people who bring attention and care to each engagement, rather than consulting on the side of a full-time job.
A track record. We generally work with experienced professionals who have already led several projects and can give at least three client references we can speak to. We occasionally take promising newcomers.
If that sounds like you, we would love to hear from you.
Working with NPB has opened doors, built partnerships and sharpened my practice. They create a space where consultants grow in confidence and fellowship. The support feels professional yet personal, like being part of a family walking a shared journey of change.
Grantees supported by some of the world's most respected foundations, at the forefront of social innovation and climate action. Growing, experimenting organizations that appreciate experienced professionals.
Forget endless RFPs. When a grantee is interested, you're invited to a short matching call. If it's a fit, you write a concise statement of work. Most projects are approved within two or three days.
Reliable and prompt payment
We pay consultants promptly on delivery of work and approval of invoices. You'll never chase payments or deal with complex billing systems.
We handle the paperwork
Contracting, compliance and communications with funders are on us. You focus fully on your consulting and client relationships.
Payment was prompt and as a freelancer this is so important. Thank you NPB!
Sherry Malik, coach and consultant
Working with Nonprofit Builder has connected me with organizations I might not have found on my own. The whole setup feels like a win-win-win for the nonprofits, for me as a consultant, and for NPB.
Sameen Piracha, consultant
The NPB platform has expanded my visibility beyond my usual network and created a space where both consultants and potential clients can thoughtfully assess fit before committing.

What we expect
High standards, because grantees trust us
From the first call with a grantee to the final report, quality and care come first.
Commitment to excellence
Give your best every time: respond quickly and personally, customize every proposal and deliverable, and approach each engagement with care and curiosity.
Respect and professionalism
We value kindness, open-mindedness and humility. Respect for different perspectives, cultures and working styles is essential.
If something isn't going as planned, reach out. We'll help resolve issues, advise on scope or client relationships, and make sure every project succeeds.
Charles is very flexible and easy to work with. Very responsive, no jargon. We all felt that he really wanted to help. This led to very focused input and practical help.
