As answered by people managing Keepa and SkepticalProof.
SkepticalProof's answer:
SkepticalProof is decision-first rather than dashboard-first. It brings market, customer, and demand evidence together with contradictions, risks, and conditions to produce a clear, explainable product opportunity decision. Users can see not only what supports an opportunity, but also what argues against it and what could change the decision.
SkepticalProof's answer:
SkepticalProof is designed for people who want to move from product research to a decision. Instead of simply presenting more data to interpret, it helps organize the available evidence into an explainable conclusion, while making uncertainty, risks, and opposing evidence visible.
SkepticalProof's answer:
SkepticalProof is currently built for Amazon sellers, aspiring sellers, and product builders evaluating product opportunities in the Amazon US marketplace, especially those who want a structured, evidence-led way to decide whether an idea is worth pursuing.
SkepticalProof's answer:
SkepticalProof was created around a simple problem: product research can produce more and more information without necessarily making the final decision easier. The product was built to connect evidence, challenge an opportunity rather than simply confirm it, and help users answer the practical question: is this opportunity actually worth pursuing?
