The mayority of people (<79%) would share their cars with friends and neighbors, but they fear insurance problems and trouble for their friendships.

Why testing the feasibility of an idea from different perspectives is a crucial first step

Are we able to build this?

What partners do we need to realise this idea?

Do people actually have this problem?

Are people willing to pay for a solution?


You have to be creative on this one. Especially because the experiments should be done low budget. In our case we used a combination of Instagram Ad’s and a Sign Up page to validate the need.


⚠️ Our biggest problem was to find the right insurance partner who is willing to work with us.

Outputs: User Interviews, Instagram Campaign, Landing Page, WhatsApp Group MVP

"When my neighbor told me that she regularly takes a rental car, I immediately offered her to take my car instead."

After 2 long years, we have finally found the right partner for our business.

Why Market Analysis Is Crucial for validating a business model, understanding market size, and assessing competition.

→ What is the USP of our product?

Is the market size big enough?

Who are the competitors?


Answering those questions gives a solid understand of your business model. You get a deeper understanding of the market and your competitors. Understanding those numbers will help to articulate the business idea in front of stakeholders and investors.


⚠️ The market size is a relative figure because no one owns the entire market. Since this is just a validation it should simply indicate if the market is interesting enough in size.
