Raising capital is a tedious task and requires lot of patience and dedication, be it in start or either you want to expand your business, the reason is that any investor would only want to see who their money will grow and in how much time they would be able to get their money back with profit.
So I would like to answer this question taking two scenario when your business is in starting phase and other is when it has gone some amount of traction from the market .
When your business is in nascent phase:
In this phase you have to face a lot of struggle and challenges, it might be you have to go to around 200+ sources and even won't be able to get any amount of funding, but then you have to introspect your venture and try hard for it.
In this phase, you can either use your own saving or can get some funding from your friend and family and use it to give a kick start for your venture.
Further you can even approach to some venture capital to ask for funding( but in today's time generally VC firms like to invest in established startups who had gain certain traction from the market).
Else you can even approach to bank and ask for loans for your startups.
When you have established venture:
In this phase it would be more easy to raise funds from some established VC firms, you can go for series B,C,D funding if you get in contact with a good VC firm.
In this phase also you can approach to bank and ask for loans.
