Help me in figuring it out!!

I am currently working as a Product Intern at a remote based USA Fintech startup. I have a full time role with me with the top company of Big 4. As a stipend I am currently getting $800 a month from my current internship. I am in my final year of engineering and the offer with Big 4 was like ( 6M + Full Time) when I received it last October but they did not say that the 6 month intern will start From July 25 after my graduation instead of starting from Jan 2025. Now the problem is I don't want to undergo another 6 months internship from July so I am searching for another FTE off campus which I can join from July 2025. The startup in which I am working is undergoing a cash crunch but it is probable that it will get funding soon. Now I wanted that if it gets the funding of around $ 5M I wanted to continue in it as a full time Product engineer as till now work pressure is normal and I am learning new technologies. The total strength of the startup is around 10 people. When I told this to my parents yesterday I was told that I should not join that startup even if it gets > $5M funding claiming that it don't have the brand while something else is also the problem. My current stipend * 12 > FTE compensation per annum of my Big 4 offer. So I think if I join that as full time I will easily get $1.5k-2k per months as salary all in cash. Money is very important for me, as I am a middle class guy. Please help me what should I do.
