Hello! I am looking for the market valuation and estimated yearly growth rate for the food delivery business in Algeria.
If I can't find this information how I could calculate an estimation for this market?
These questions should be answered in your business plan. Have you written one?
This is not information someone is going to just give you. You have to do the research firsthand. Learning how this information is composed, what indicators affect the figures, looking at the industry history, looking at other models, comparing the differences geographically, all lead to developing your expertise and understanding in a way that helps you define the opportunity, calculate risk, and determine your plan.
If it were easy to flip through a book and find the answers summarized for you, all the opportunities would be grabbed by lazy people. Your ability to interpret and both identify and solve market issues is what makes you an entrepreneur.
Big numbers don't matter anyway. It's like saying the real estate market is a $350billion industry. It means nothing. You have to know what your addressable market is and what their likelihood of participation is. There's power in being first when it comes to gaining market share. If you can't be first, then you need to be different (the most or best).
You won't be able to compare Algeria to any other market, although you can still apply business models to what you learn about your local market and see if they have a likelihood of working.
Basic research usually starts with talking to the people/companies already doing what you want to do. Then you talk to their customers about what is and isn't working. You can develop your own estimates using real information. I have no idea if there is any kind of trade association who is monitoring the type of activity you're interested in, but in the USA, that would be another place to conduct research.
