Hi, I’m Charlotte Bertha, and I founded Sustainability Arc with a simple but urgent mission: to restore balance between humans, the planet, and technology. Today marks a major milestone — the launch of my very first digital guidebook, and the beginning of a community I hope will grow into something powerful.
I created “How to Build a Purpose-Driven Nonprofit in Florida (Fast, Easy, & Cheap)” because I know how confusing, complex, and bureaucratic the process can feel — especially when your ideas are mission-driven, not profit-driven. This guide simplifies everything, step-by-step, from state filings to 501(c)(3) recognition. It’s the exact blueprint I used to start Sustainability Arc.
In this downloadable booklet, you’ll learn:
• What makes a nonprofit purpose-driven
• The 3x3x3™ structure I used to organize my organization
• How to complete your state and IRS filings quickly
• What to do after you incorporate to attract grants and build credibility
You can get the guide right now for just $10 on Gumroad:
