How many people make a startup? 1? 2?
How many ideas do you need to have?
Do you need to start with something, anything, and just get going?
Do you need funding to support those you work with?
Do you need to pay yourself?
What are all these things and how do they contribute to what you are doing?
The beauty of startups, unlike many other fields, is that they can take any form you want, any direction you want, and any course you plot.
It’s all up to you how you do it, either path (and there are many) is fraught with challenges.
The only real question isn’t the makeup of your startup or what you do, but rather are you committed to seeing it come to fruition?
