Where can you listen?

Proof of Impact is the nonprofit podcast that actually asks the hard questions.

The sector is full of people doing extraordinary work, and a culture that is very good at staying comfortable. No pushback. No tension. Just carefully managed conversations that leave the most important things unsaid.

Host Elizabeth "E" Kitzenberg has spent decades inside the nonprofit world, leading major campaigns at Dana-Farber Cancer Institute and Harvard, and now running The Kitzenberg Group, her own institutional fundraising consultancy. She knows where the guard goes up. This show is about what happens when it comes down.

Honest conversations with nonprofit leaders. No filter. No apologies.
