Dev's test: his decision agent saves ~$13.5K per build vs ChatGPT and Claude across 10 simulated startups

KicksStandLabs · reddit · 2026-09-12

A developer ran 10 simulated business ideas through ChatGPT, Claude, and RESORSA (the platform he's building) with identical inputs and no cherry-picked prompts, tracking money needed for a meaningful test, whether unnecessary spending got challenged, whether shaky assumptions were flagged, and whether pivots were recommended.

Results: RESORSA's recommended paths averaged $13,500 less per build, mostly from boring decisions like validate-before-build and rent-don't-buy. 7/10 businesses made it on the original path; the other 3 only succeeded after RESORSA recommended a pivot while the other two models kept pushing the original plan. Median Time-to-Artifact was 38 seconds, with one 4-minute outlier.

The author admits his bias and that 10 simulations prove little; next steps are more simulations and comparison against real builder behavior, with ugly results to be published too.
