Tech debt is a financial instrument.
You borrow speed from the future to survive today. But most founders let the interest rate wipe them out.
Don't apologize for bad code. Manage the loan.
Here is the system to treat your repo like a balance sheet:
"We aren't sloppy. We are intentionally aggressive." You are buying time. Make sure you know the cost.
Categorize every issue ruthlessly:
→ Accept & hold (strategic shortcuts) → Manage (monitor closely) → Kill (blocks revenue)
Don't ask for refactoring time. Present a 70-30 split: 70% growth. 30% debt paydown.
"We rewrite the billing system at $2M ARR." "Before that, it's a waste of capital." Manual entry is more efficient than automation early on.
Founders don't care about clean code. You care about predictability. Devs must show you the volatility. "High debt = I can't tell you whether this feature takes 2 days or 2 weeks."
Perfect code is for art. Profitable code is for businesses.
Only if you pay the debt before foreclosure.

Your friends are terrible hires. Not because they lack skill. Because you'll never treat them like employees. I did it years ago. Almost destroyed friendships...
