The Lean Startup is an approach from Eric Ries. In his book “The Lean Startup”, he talks about his story and his unique way of founding a business. While working in different teams as a product developer, Ries faced a lot of failures. After a while he found a way for startups to grow faster and cheaper.
To follow the Lean Startup philosophy means to launch a product in a phase in which it hasn’t reached the point of complete perfection. By selling a first version of the product and continuously collecting data and feedback from the customers, it is then easier to optimize the product step by step until the point of complete satisfaction is reached.
Instead of wasting months through making assumptions about what the customer wants, it is quicker to bring it to the customer straight away and either fail and start new or find a market and improve.
