Thinking of a Startup?

Take the following steps based on your current stage in order to progress:

Stage 1:
You want to do a startup, but do not have any idea yet

Wait for a decent idea to strike. Keep looking around
Till then work with some other startup to learn the nuances of how to run a startup.
Find a co-founder, you always need a partner in crime.

Stage 2:
You have a Startup Idea, but do not know your Customer

Figure out your Ideal Customer Persona (ICP).
Do not build the product until you know who to sell and how to sell.

Stage 3:
You know your Customer, but have not spoken to them yet

Speak to at least 100 potential customers, before you start building Product.
Try to sell the idea/concept to your ICP and if possible ask for some advance money.

Stage 4:
Your Idea is Validated but you are yet to build the MVP

Only if compulsory, build a very small MVP that explains the whole concept you are envisioning.

Stage 5:
You got the MVP

Now you are ready for next step. Start approaching with all the details you have gathered so far to Incubator/Industry Expert/ Mentor/ Angel Investor

Remember that these steps are general guidelines, and your specific situation may require adjustments. Continuously reassess your progress and adapt your approach accordingly.
