Just wanna to share my story:

I just quit my job 2 months ago to ramp up my own startup. I will be funded with 2k Euro per month for 1 year to prepare the founding of my startup. Basicly that means i got one year to build backend/frontend/app. I have a friend that is doing some nontech related stuff like business development and shit. Sounds good until now i guess.
But:
Developing all that stuff in a one man show as a junior-like developer is really hard. I did not find another dev who wanted to join me as a sideproject or something.

Do you guys think thats even possible to ramp up all this by myself or am i to optimistic? I mean, i learn a lot atm, but i am a bit scared to fail too.

That should not be whining or shit, just gathering some input of you guys.

(excuse typos and stuff as i am not a native speaker :) )
