NotaBeen began not just to fight email clutter, but to solve a fundamental trust barrier in modern AI tools. As a developer, I saw that professionals were hesitant to adopt powerful new email AI because they couldn't verify what was happening to their sensitive data. For nine months, I built the core engine, realizing that true professional adoption would require more than just efficiency, it would require auditable, verifiable transparency. This became the non-negotiable principle driving the entire project.
The shift to an Open Core business model was a strategic imperative. It allows us to:
1. Offer the NotaBeen Core (MIT-licensed) for those who demand absolute data sovereignty via self-hosting and full code transparency.
2. Offer NotaBeen Professional (Paid SaaS) to provide the highest ROI through managed service features like Intelligent Risk Prioritization and guaranteed AI Actions, ensuring a sustainable business that can develop the core engine for everyone.
This dual approach directly addresses the market's need for both uncompromised trust and professional-grade efficiency.

Founder & Full-Stack Developer
As the full-stack developer, I built NotaBeen from the ground up, but my focus has shifted from just code to community and commercial sustainability. I am committed to leading a vibrant, developer-led community that uses the Open Core model to build the future of auditable, high-ROI email tools.
Our vision is simple: to make NotaBeen Core the indispensable, MIT-licensed foundation for every professional and enterprise seeking transparency, and to make NotaBeen Professional the most efficient, high-ROI managed service available. We believe in a future where trust is not a promise, but a line of code you can inspect.
