Happy to answer any questions about the situation. A few things worth noting:
Our finances are fully transparent: monthly reports are public via Open Collective and our Open Startup Reports. The shortfall came from a small number of key members re-budgeting, not from declining usage. Mautic's install base is actually growing. We've already cut costs significantly (40% reduction in Project Lead hours, cancelled a developer hire, suspended events). The $140K essential budget covers codebase management, infrastructure, and trademark protection.
The broader question of how open-source projects that serve as critical infrastructure can sustain themselves financially is something I think about a lot. We're trying to be transparent about navigating it in real time.
