Pivoted to SaaS, Found Product Market Fit, but Drowning in SBA Debt, I will not promote

I’ve been grinding on my startup since before 2020. It started as a service based business, and I was all in on that model for years. But I made a lot of mistakes which mainly, I scaled up a team I didn’t actually need. By the time I realized it, I had already racked up about $300K in SBA loan debt. Last year, I finally pivoted to SaaS, and it changed everything. I found product market fit, and MRR is starting to pick up. The problem is my cash flow is tight because I spent so long operating as a service business with unnecessary overhead. Now I’m at a crossroads. The brand is strong and essential to this business, so rebranding isn’t an option. But the debt is crushing, and I don’t know the best move forward. Would investors even consider me with this debt? Should I be looking at bankruptcy first and then seeking funding? On top of that, I went from having a team of 15 to just me now. I’m realizing I might need a mentor or even a cofounder, but I don’t know what type of person I should be looking for. Should I be prioritizing someone with finance expertise? A growth operator? A technical cofounder? Ive made so many mistakes and I don’t want to continue. I feel really lost right now, but I know I have something solid with this SaaS. I just don’t know how to navigate the next steps. Any advice would be hugely appreciated.
