Renewable Energy × African Mining Solar (Hybrid Power)

killed: Existing pharmacy intelligence platforms (Bluesight, GPO tools from Vizient and Premier) already have the data infrastructure. Crisis-mode dashboard is a feature they add in days, not a new product. Crisis-driven urgency benefits incumbents.

killed: Pharmacies have zero incentive to share real-time stock data (benefits competitors). Crowdsourced pivot fails from frequency trap (individual patient searches rarely) and medication privacy concerns. Two-sided marketplace where one side won't participate.

killed: Denied claims appeal automation is a crowded space with 10+ funded competitors (Waystar, Experian Health, Change Healthcare/Optum, Infinx, Apixio, AKASA) and deep EHR integration moats. Olive failed from unfocused execution, not market absence.
