When you raise finance, where is this capital allocated?

Hi Hackers

When I set out on my journey to create the Motorworx Market, I decided early on I was going to 'Bootstrap it'

I justified this by realising there are a lot of tools out there now that can speed up development process's really quickly, such as the wave of no code tools and agency's supporting them. However I am starting to realise I cant do everything, I am trying to cover a lot of ground with minimal results.

Throughout my journey so far, I see a this constant vibe about Start-ups raising funding, which is all very exciting, and it got me wondering...

Where do these start ups spend this new money?

So to work this out I need your help as I would like to find out how start ups use this money to establish / grow / validate / build / (fill the gap) their business after they have received funding. I have broken this down into two basic questions.

If you have raised capital in the past, can you share 3 areas of your business where you have prioritised the allocation of this new capital, and how long did it last before the business was sustainable?
Same question as above, only if you have not raised any capital yet, and what areas of your start up do you expect to use it?

I appreciate these questions are quite vague, so any feedback here would be greatly appreciated. I literally have no idea what the answers would be, but hopefully if a common theme occurs it will help narrow down my own energy into the right places.

Regards
