LEAN Startup Feedback Cycle

What is LEAN Startup?

LEAN Startup is a method for creating a startup business and was developed by Eric Ries based on his experiences in developing startups. LEAN Startup is the de facto standard in the market. Below you will find a description of LEAN Startup including references to commonly used models, such as Value Proposition, Personas and Customer Jouneys. You will also find more about validated learning and LEAN Startup phasing: problem fit, solution fit and market fit.


Almost all founders can tell you  that creating a startup company is hard work and that many challenges need to overcome. There is no such thing as an 'easy startup'. However many founders succeed, and you can be one of them. Don't forget to ask yourself the question if you have the right talents to be an entrepreneur of a startup company. If you need more help on you startup, Red Harbour can help you with coaching and consultancy. 

What is a Startup?

Not every starting company is a startup. A startup is a company with an innovative idea. The product that results from this idea is both scalable and repeatable and has been made possible by the latest technology. The future of a startup is uncertain, because at the start it is unknown what customers think about the product. Often a startup doesn’t know its customers, let alone it knows if it approaches the right customers. Read more...

Advantages of LEAN Startup

There are many examples of entrepreneurs who have made a successful business with a powerful idea. The unicorns are the most appealing examples of this. Dutch unicorns are e.g. Adyen, Mollie, Messagebird, Bunq and Gitlab. In contrast to the successes, there are also many startups that cease to exist, due to bankruptcy or closure of the company. These causes may lie in the idea's lack of commercial potential as well as the lack of entrepreneurship.


The LEAN Startup methodology aligns with the success and failure of startups by:

1. Fast learning about what does or does not work

2. Experimenting on a small scale

3. Lower loss of time and costs


Depending on the potential of the idea and the amount of time you need to develop your proposition, the cdevelopment of your startup can go very quickly or very slowly. In the latter case, the advice is to stop in time. If there had been potential for your idea, you would have realized it much earlier. Dare to stop! That saves time and costs. It is better to put that into the development of another idea.

Keep the iterations as short as possible

1.Problem fit:

validate the problem is a problem worth solving

2.Solution fit: validate the solution solves the problem

3.Market fit:

validate a profitable company can be developed

LEAN Startup has 3 phases

1. Problem Fit

2. Solution Fit

3. Market Fit

Work out the models below for each phase. It's absolutely necessary to work closely with (potential) customers. Read more about this in the Mom Test. A common pitfall is to have too much faith in the potential of the solution and thereby insufficiently validate the customer's problem. Don't underestimate the importance of the problem fit.


Work in short iterations in accordance with the LEAN Startup feedback cycle.
