One of the concerns people have when looking to create a new company or organization is “someone is already doing it”. The reality is, this might be true.
The question you should ask yourself when you realize someone is already doing what you want to do is “does it matter?”
Currently there are around 7.4 billion people on earth. How many of them already have the good or service you are offering? How many of them need it? If many more people need it then currently have it, then there is a market to go after.
You do have to consider the geographical issues. While there might be 7.4 billion people on earth they might not all have access to what you are offering based on location. Can you overcome the geography issues? What about the language issues you might need to overcome.
Don’t be too worried if other people are doing what you want to do, there are a LOT of people out there, you just have to figure out how to reach them.
Have a great day!
