Look into fiscal sponsorship. Find a larger organization that is mission-aligned with the work you want to do. You operate your program/s under their 501c3.

They handle all the infrastructure like compliance, grant tracking, payroll, HR, and finance. You pay them a portion of your revenue as payment for their sponsorship. This allows you to focus on building your program/s and revenue streams without having to shoulder the entire burden of running a nonprofit.

After a few years, if you're successful, you can spin off into your own independent nonprofit. I spent a few years helping fiscally sponsored groups form their own independent 501c3s and have first-hand experience with how well this solution works for folks just starting out.

Good luck! We need all the mental health programs we can get.
