The Core Goal of Entrepreneurship Is Validated Learning, Not Executing Plans
Startups are not executing a known business plan but searching for a sustainable business model. Therefore, the core activity of entrepreneurship is not execution but learning — validating assumptions about customers, markets, and products through rapid experimentation.

MVP Is the Fastest and Most Economical Tool for Validating Assumptions
A minimum viable product is not the worst possible product but the version that allows the maximum amount of validated learning with the least effort. Through MVP, entrepreneurs can quickly test whether the most critical assumptions hold before investing significant resources.

Pivot Is a Strategic Tool in Entrepreneurship, Not a Sign of Failure
When experimental results indicate the current direction is not viable, pivoting — retaining validated learning while changing strategy — is the right choice. The ability to quickly identify pivot signals and decisively execute is one of the core capabilities of excellent entrepreneurs.

The Greatest Waste in Entrepreneurship Is Building Products Nobody Wants
The biggest problem with traditional entrepreneurship is spending enormous time and money building complete products without validating market demand, only to discover nobody wants them. Lean Startup eliminates this most fundamental waste through early validation.

Innovation Requires a Dedicated Measurement System to Assess Real Progress
Traditional financial metrics cannot measure the true progress of early-stage startups because they reflect past execution results rather than the possibility of future growth. Innovation accounting evaluates whether startups are truly progressing through actionable metrics, benchmarks, and learning milestones.

Build-Measure-Learn Cycle
Transform the entrepreneurship process into a scientific experiment cycle by rapidly building minimal experiments, precisely measuring key metrics, and learning from data to make decisions.
Dropbox's Drew Houston used a 3-minute demo video as an MVP to test market demand without an actual product; overnight registrations grew from 5,000 to 75,000, validating market demand before fully developing the product.

Minimum Viable Product (MVP)
Build the product version that can validate the most critical assumptions with minimum effort, avoiding wasting resources on unvalidated assumptions.
Zappos founder Nick Swinmurn first posted shoe photos online before building any inventory or technology system, buying from physical stores and mailing them when someone ordered, using this manual method to validate market demand for buying shoes online.

Pivot Decision Framework
Based on validated learning data, identify when to persevere with the current direction and when to change strategy, rather than deciding based on intuition or pressure.
Instagram was originally a check-in app called Burbn with complex features and slow user growth. Founders discovered through data that users' favorite feature was photo sharing and decisively pivoted to a photo-sharing-focused app, eventually being acquired by Facebook for $1 billion.

Innovation Accounting
Replace vanity metrics with actionable metrics, building a measurement system that can truly measure startup progress and give data-based foundations to innovation decisions.
Many startups use total registered users (vanity metrics) to measure progress, but this cannot reflect real user value. Lean Startup recommends using actionable metrics like retention rate, active user ratio, and revenue per user, which can truly reflect whether the product is creating value.

Serial Entrepreneurship and Learning from Failure
2001-2007
Accumulating experience through multiple entrepreneurial failures, gradually forming the core insights of the Lean Startup methodology
After graduating from Yale University, Ries joined multiple Silicon Valley startups and experienced multiple failures. In 2004 he co-founded IMVU (an instant messaging virtual world), experiencing typical startup difficulties in the early days: spending enormous time building a product, discovering users didn't like it, and having to relearn. These experiences prompted him to systematically think about entrepreneurship methodology.
Formation and Dissemination of Lean Startup Methodology
2008-2013
Systematizing IMVU's practical experience into the Lean Startup methodology and disseminating it to entrepreneurs worldwide through blogs, speeches, and books
In 2008, Ries began systematically articulating the Lean Startup concept on his blog, quickly resonating in the entrepreneurial community. The Lean Startup was published in 2011, becoming one of the world's bestselling startup books. Ries began speaking worldwide, and the Lean Startup methodology was widely adopted by startups in Silicon Valley, Europe, and Asia.
Enterprise Innovation and Long-Term Stock Exchange
2014-present
Extending the Lean Startup methodology to large enterprises and founding LTSE to drive long-termism reform in capital markets
Ries published The Startup Way, a sequel to The Lean Startup, applying the Lean Startup methodology to innovation management at large enterprises like GE. During the same period, he founded LTSE (Long-Term Stock Exchange) to provide a listing platform for companies committed to long-term value creation, which received official SEC approval to operate in 2020.
