Ask HN: When did you decide it was time to raise capital?

I founded a company about 5 months ago. We're currently at roughly $60k MRR, profitable, and I only have one employee.

We've spent essentially nothing on marketing. Most growth has come from outreach, referrals, and customer demand.

I’m wrestling with two questions. First, at this stage, would you raise capital or continue bootstrapping? Second, how did you determine what was actually limiting growth in your business? Was the bottleneck engineering, sales, marketing, or something else?
