Station F Global Prover

European startups raise half of what American startups raise — and still think locally. One country. One language. One regulatory framework treated as a burden instead of a barrier that protects them. Station F exists because Europe has 450 million consumers, world-class regulation, and an ambition problem. This tool forces five Station F-level axes: global-first strategy, regulation as moat, capital efficiency, ecosystem density, and continental ambition.

YC Startup Prover

Most startups die building solutions nobody asked for. A founder pitched for 20 minutes about their proprietary algorithm — never mentioned a single user, a single pain point, a single dollar of willingness to pay. That pitch would be rejected in 30 seconds at Y Combinator. This tool forces five PG-level axes: problem discovery, unscalable beginnings, metric discipline, user obsession, and core value focus.

Watt Efficiency Prover

A team spent 6 weeks 'optimizing' their operation. No baseline. No analysis. They restructured the most visible department. Processing time got worse. The bottleneck was a manual approval step in a different department — untouched entire time. Watt measured the Newcomen engine and found 80% of steam energy wasted reheating the cylinder. He did not 'optimize the engine' — he measured, identified, and eliminated specific waste. This tool forces that discipline: identify waste with data, instrument baselines, design feedback, isolate the bottleneck, and quantify improvement with numbers.

Traffic Manager Prover

A startup spent $180K on Meta Ads and reported ROAS 4.2x. The board celebrated. Then someone ran an incrementality test — a 10% holdout that saw no ads. 38% of 'attributed' conversions were organic users who would have purchased anyway. True incremental ROAS: 2.6x. $68K spent on people who needed no convincing. Platform-reported ROAS is fiction. This tool forces five axes: unit economics per channel, attribution integrity with incrementality testing, funnel diagnostics at every stage, creative performance with fatigue analysis, and audience architecture with saturation awareness.

Techstars Mentor Prover

A founder pitched for 45 minutes without mentioning a single customer conversation, a single mentor challenge, or a single dollar of revenue. Zero feedback sought. Zero market validation. Zero network. That is not acceleration — that is solo building in a vacuum. This tool forces five Techstars-level axes: mentor leverage, feedback discipline, customer discovery, revenue readiness, and network strategy.

Grade A+ 1 tool Business TechstarsAcceleration

Technical Writing Prover

An AI wrote API documentation for 'developers.' No expertise level. No prerequisites. A wall of text with no headings. Code examples that referenced a deprecated method — untested. Passive voice throughout: 'it is recommended that the configuration be updated.' A junior engineer followed the docs, deployed to production with the wrong config, and caused a 4-hour outage. This tool forces audience definition, task-based structure, tested examples, ambiguity elimination, and completeness verification.
