US startups are burning Series A and B runway on something their investors didn't fund.
Tech debt.
Not the intentional kind — the "we'll fix it later" kind that was supposed to be fixed 18 months ago.
The math nobody talks about:
→ $500K in deferred engineering decisions
→ 3 senior engineers spending 40% of their time on maintenance instead of features
→ Every new feature takes 3x longer than it should
→ Your roadmap is 6 months behind before Q1 starts
Founders who raised on a product vision are now explaining to their board why the product doesn't work the way they described it.
The window to fix this is before your next raise — not after.
What "paying down tech debt the right way" looks like:
✅ Audit first — understand what you actually owe before you start paying
✅ Strangle pattern — replace legacy components incrementally, not all at once
✅ Freeze the debt — stop adding to it while you're fixing it
✅ Measure it — if you can't quantify it, you can't prioritize it
Founders and CTOs between Series A and C — what's the tech decision from your early days that's costing you the most now?
