How does the Lean Startup methodology utilize customer feedback to enhance agile management and mitigate entrepreneurial risk?

The Lean Startup method treats every customer interaction as a data point that tells whether a product idea works, so teams constantly test hypotheses with real users. By launching small, minimum‑viable versions and measuring how customers actually use them, founders learn what features matter and what problems still exist. This rapid feedback loop lets teams pivot or persevere quickly, keeping the product roadmap flexible and aligned with real needs. Because decisions are based on evidence rather than guesswork, the risk of building something nobody wants is cut dramatically. For example, a startup that tests a simple signup page first can discover that users prefer a single‑click sign‑up, then re‑design the flow before investing in full‑blown authentication systems.
