If all the team talks about is money that you will earn without any explanation how they will make that happen and also no technical professionals behind it it's a big red flag.
It certainly is.
A project should be focusing on its development and that's what they should boast of and not on how much money you can make. If they have that type of guarantee and promise, it's likely that they'll giving false promises and that should be taken into account by potential investors.
Money will follow the project if the development is great but there's no guarantee that even it's successful, they're still prone into some rejections and possible losses at the start.
