The Lean Startup method has become one of the world’s most influential methods for teaching and practicing entrepreneurship. Popularized by Stanford Adjunct Professor Steve Blank and entrepreneur Eric Ries – and first tested in the Stanford Technology Ventures Program classroom in 2012 – Lean Startup is the practice of making an entrepreneur’s assumptions about a business idea explicit, then engaging in deep inquiry to test those assumptions. The methodology rapidly became a common and trusted innovation and entrepreneurship method; it has been adopted across sectors and is taught in institutions worldwide, from universities to the Department of Defense.
Stanford has played a critical role in developing, teaching, and studying evidence-based approaches to entrepreneurship, including Lean Startup practices. STVP has also conducted ongoing evaluation and research on the method, led by Riitta Katila, Professor and STVP Faculty Director. A trio of Stanford studies, including two jointly supported by the Stanford Initiative for Entrepreneurs' Resilience & Well-Being, explore the role of Lean Startup in the entrepreneurship ecosystem.
How Lean Startup Changes Decision Making
First, in 2020 in the Strategic Entrepreneurship Journal, Katila and STVP PhD alum Michael Leatherbee (now at Universidad Católica de Chile) explored Lean Startup’s role in teaching entrepreneurs to formulate and test hypotheses. Establishing the behavioral effect of the method, Katila and Leatherbee found that the Lean Startup’s emphasis on “customer discovery” – testing business hypotheses with potential customers during product development – helps teams converge on business ideas. Additionally, they found this process also sparks entirely new hypotheses, revealing that Lean Startup is not just a mechanism for reducing uncertainty, but also for inspiring new ideas. They also found that MBAs, while hesitant to embrace the method, are especially successful when they choose to employ it.
Turning Negative Feedback into Positive Outcomes
The second study, published in the Strategic Entrepreneurship Journal in November 2025, offers a quantitative review of Lean outcomes. Katila, together with D. Carrington Motley (another STVP PhD alum, now at Carnegie Mellon University), and Leatherbee, interrogate how Lean Startup influences entrepreneurs as they receive negative feedback. The authors’ found that negative feedback improves commercialization outcomes only when entrepreneurs are willing to reconsider the core of the opportunity, rather than merely adjusting peripheral features.
How Lean Startup Stacks Up within Experimentation
The latest study, an Academy of Management Annals 2026 paper by Katila, Leonardo Corbo, and Božidar Vlačić, looks at the larger intellectual landscape surrounding entrepreneurship, where Lean Startup is one form of experimentation. The authors reviewed 177 empirical studies across several disciplines. Their resulting, unifying framework highlights the key drivers, processes, and outcomes of organizational experimentation, finding that different experimental processes serve different purposes, and their effectiveness depends on a range of factors. The authors place Lean Startup and its core tool, the Minimum Viable Product (MVP), inside a “problem-solving” style of experimenting, relying on quick, iterative trials to solve problems and using real-world feedback to constantly adjust. They suggest future research should explore how organizations can better retain what they learn from these fast-paced experiments and apply them to big-picture company strategy.
Lean Startup as a Catalyst for Innovation
Overall, this research progression indicates that Lean Startup has measurably improved entrepreneurial decision-making – but experimentation does not automatically produce learning. Its value depends on whether entrepreneurs formulate meaningful hypotheses, generate informative feedback, interpret negative evidence accurately, and are willing to pivot when necessary.
“The true novelty of this research stream is showing that Lean Startup can be a source of entirely new ideas,” says Katila. “You may go in thinking that you are repeatedly testing an existing idea, but come away with something new because experiments fail, yield surprising results, or reveal valuable side insights.”
Ultimately, the Lean Startup method works not because feedback automatically reveals the answer, but because it helps entrepreneurs question assumptions — and, when necessary, change the core of what they are building.
