"No "hockey stick" growth, just small victories we fought for and earned each day. Somedays, we messed up. We couldn't always give 100%. I probably beat myself up too much for it."
This is important. Sometimes founders question themselves when they do not see hockey stick growth. Your product may not be in the kind of business that sees such growth or you may be growing slowly and steadily. The OP's persistence paid in the end.
Congratulations.
