AI is rewriting the unit economics of software

Something is changing in the unit economics of software

Traditional SaaS enjoyed 75–85% gross margins from near-zero marginal cost of serving extra users. AI products break that: every user interaction triggers an inference call with real compute cost. ICONIQ's 2026 survey puts average AI product gross margins around 52%. For the first time, margin and product quality conflict on a per-unit basis. Usage-based pricing is replacing flat subscriptions because power users can blow up margins. Inference costs are falling, but Jevons paradox means call volume will grow faster—cost savings won't turn into margin improvement.

Why it matters: Uses ICONIQ survey data to make the margin compression story concrete: 52% for AI products vs 75-85% for traditional software. The knock is that it's a personal blog opinion piece, not primary research, and we only have the excerpt — the full argument isn't visible.

This piece nails something a lot of people sense but haven't quantified: traditional SaaS had 75-85% gross margins because serving one more user cost almost nothing. AI products break that—every user action triggers an inference call with real compute cost. ICONIQ's 2026 survey puts average AI product margins at 52%, a 20-30 point gap from old SaaS. Two things follow. First, the old playbook of burning cash to grab users and waiting for margins to improve at scale doesn't hold anymore, because inference costs scale with usage, not away from it. Second, usage-based pricing will replace flat subscriptions—a power user making 100 calls costs way more than a casual user making five, and flat fees can't absorb that spread. What the post doesn't dig into: that 52% figure might already be inflated by companies doing model routing and using smaller models for routine tasks. The real number for many AI products could be lower. I'd read this as a signal that AI product economics are drifting toward hardware-style cost structures, where every unit has a bill of materials, and founders need to think like manufacturers.
