DIY With AI, Or Hire Consultants? The 18-Month Cost Sheet for Custom Enterprise Apps

AI makes "just build it ourselves" look trivial: two internal engineers, Cursor plus Claude Code, a working demo by week 4.

This essay walks the timeline of the DIY-with-AI path — what it looks like at week 4, month 6, month 12, and month 18 — and why the gap between expert and non-expert AI use is the 5–10× output multiplier that decides which path you actually walk.
