For example, Airbnb is not always a community-driven hotel company. It used to revolve around an air cushion on the floor of the living room. Airbnb was originally called airbedandbreakfast.com and was founded during a popular design conference in San Francisco. The founder provided participants with an air bed and breakfast in the living room. They had some success in the early days, but wanted a better PMF. Therefore, they no longer just focus on meetings, but instead look for travelers who need to stay anywhere in the world. They started charging for their services as a way for travelers to find local, authentic accommodation and the Internet at the same time. And, of course, you can get a free breakfast every morning. After listening to the feedback, they became Airbnb and started to help anyone list or book any type of accommodation (castles, private islands, etc.) in 34,000 cities around the world. The rest is the history of PMF.
