• Entrepreneurs are everywhere. 
• Irrespective of the size of the venture if you guys are working on a product that solves a problem in a new and better way then you are entrepreneurs
• Entrepreneurship is management. Startups need a new type of management that will handle the conditions of extreme uncertainty.
• Confirmation by facts. A startup needs continuous learning through a scientific approach and empirical hypothesis testing.

• Instead of making complex plans based on many assumptions,
•  you can make constant adjustments with a steering wheel called the Build-Measure-Learn feedback loop. 
• Startups are greatly analogous to driving a car to our office as we know the destination but we may change the routes according to our ease  

The feedback that a startup receives in its experiments

 can be qualitative (which product options they like and which they don't) 

or quantitative (how many customers use the product, the number of registered users).

The Lean Startup concept is based on a Build-Measure-Learn feedback loop.

 The most important challenge of startup management is to strive to reduce the feedback cycle time. But all the elements of this cycle deserve equal attention.

• For a startup, you need to start creating a Minimum Viable Product (MVP) as soon as possible. 
• MVP is a version of a product that allows you to start the Build-Measure-Learn cycle with minimal effort, spending as little development time as possible.
• Such a crude product may be devoid of the options that will be most appreciated by customers in the future. 
• Still, at the same time, enough to be usable and understandable by first users.

1. Video MVP {A video that explains your product or solution to measure traction}
2. The Concierge MVP {idea that when you’re just starting out you don’t need to be able to handle thousands of customers, you just need to make one customer happy} great way to validate your hypothesis
3. The Wizard of Oz MVP. In a Wizard of Oz MVP customers believe they are interacting with your technology product; however, the reality is that behind the scenes a human is doing the work
4. Landing Page MVP: make a landing page with an explanation of your solution if people are showing interest and interacting its a good sign 

• "Measure" means determining whether the efforts to create a product are producing the desired results. 
• And this is the key difference between Lean Startup valuation and standard methods, where deadlines and budget utilization are assessed, 
• but it may not be considered that the startup has created a useless product. 
• The primary assessment method in a Lean startup is innovation accounting.
• This is a quantitative approach that allows us to find out how successful our attempts to trigger the growth mechanism are. It also helps identify intermediate learning outcomes.

• It means to figure out whether the chose path lead to success or we need to pivot
• When an entrepreneur sees that the chosen path does not lead to success, 
• he must be ready to find a new strategic hypothesis and stop spending money on following the unnecessary direction.

• It is not uncommon for entrepreneurs to first create a product and then find out consumers' reactions. But the point is to do the opposite.
• The goal of creating a Minimum Viable Product (MVP) is to start learning and testing in practice as soon as possible. 
• An MVP is needed to test the hypotheses of entrepreneurs. It should not be perfect. It should be quality enough to attract the first customers, but no more.

1.  Create MVP and get feedback to understand the real state.
2. Try to bring metrics closer to ideal ones. It can take a lot of trying.
3. Decide whether to move in the same direction or make a pivot.
4. If you are close to the ideal metrics, you need to move in the same direction.

• If nobody uses your product, then optimization or marketing will make no sense. 
• A startup must be very clear about making clear and well-founded predictions to prove that a good business can be built with the product. 
• The necessary indicators are often replaced by those that look nicer but are useless ("vanity metrics"). 
• These metrics usually include ad views, page visits, app installs, and more.
•  Real metrics should prove the value of your project, that it really solves user problems.

• When it becomes clear that the initially chosen path will not lead to success, 
• the entrepreneur is required to make a pivot - to radically change the strategy, create and test a new hypothesis about the product.
• The pivot's essence is to take into account everything that you have learned earlier, but at the same time radically change the strategy to get even more grounded knowledge.
• It is a combination of the scientific method of hypothesis testing and vision, intuition, and creativity.

Small batch approach

The Lean Startup methodology is based on a small batch approach, borrowed from the concept of lean manufacturing.

• When working in small batches, the finished product is produced every few seconds. 
• When working in large batches, all the finished goods are produced simultaneously, at the very end. 
• Imagine what this means when it comes to hours, days, weeks. 
• What if a customer suddenly decides they don't need a product? 
• Would we like to know about this earlier? In the small batches approach, this risk is minimized.

• The rules that govern sticky growth are pretty simple: if the acquisition rate exceeds the loss rate, then the popularity of the product rises. Therefore, companies need to track consumer losses.

• For a company to grow steadily over a long time using a paid-growth tool, it needs a differentiated ability to 'monetize' a particular group of users.
• For example, at IMVU (Ries' ex-company), this was due to introducing the ability to get off funds from mobile phones, which helped the company attract more customers than competitors who focused only on bank cards.

• The lean startup is developing a product based on the expressed desires of the market.
• The lean startup uses validated learning, which is a process by which companies assess consumer interest.
• Lean startup methods focus heavily on customer-related information such as customer churn rate, lifetime customer value, and product popularity.
• In lean startup practices, experimentation is favored more than adherence to a rigid plan.
• Lean startup standards will involve releasing a small form or early concept products to assess the customer reaction to the product.
