What are the three core hypotheses in Lean Startup methodology and how are they tested?

• A. Market size, distribution channels, and revenue streams; tested via market research.
• B. Product features, user interface, and branding; tested via usability testing.
• C. Competition analysis, pricing strategy, and channel mix; tested via sales data.
• D. Problem/needs, solution, and business model; tested via experiments, MVPs, and validated learning.

Answer: (D)

In Lean Startup, you frame your bets around three testable ideas: the problem or need your customers have, the solution you propose, and the business model that will deliver and capture value. You test these with experiments, minimum viable products, and the resulting validated learning that tells you whether to persevere or pivot. First, the problem/needs hypothesis asks: is there a real, significant pain worth solving for a defined group of customers? You test this by talking to customers, running problem interviews, and using lightweight experiments or landing pages to gauge demand. The goal is to prove that the problem is real, common, and worth addressing. Second, the solution hypothesis asks: will the proposed product or feature actually solve the problem in a meaningful way? You test this with a minimal version of the product—a minimum viable product or a concierge/make-believe MVP—to see if users understand the value, engage, and would choose it over alternatives. The feedback shows whether the core value proposition is valid. Third, the business model hypothesis asks: can this solution be delivered profitably at scale? You test pricing, distribution, and cost structure through experiments—such as price tests, channel pilots, or small-scale pilots—to determine unit economics, willingness to pay, and whether the model sustains the business. The three together form a loop of validated learning. Based on the results, you decide to persevere, pivot, or adjust the approach. While factors like market size, branding, or competition matter, they are evaluated after confirming the problem, the fit of the solution, and the viability of the business model.
