What’s a reasonable split for financial/sales vs. product dev in a new venture?

Its not an acqui-hire if acquirer needs your product. In a traditional acqui-hire the price is seen more like a generous hiring bonus.

If you're going into it as a team and building totally new stuff I would see it more as a new startup but with a premium on your team since you guys have shown you can build a product.

Fuck em. Join me and together we will rule the world, or at least the world in our minds, or just the world in your mind (stay out of mind god dammit).

I sincerely recommend you to keep going on your own for a bit longer. If you can't convince an investor then there could be one of two things happening: either the project is no good, or you simply can't explain its potential well enough. In case of the second option, try getting a friend that understands your project come with you to your next meeting with an investor. If he can be a finance or accounting person would be preferable. Good luck!

Only a large corporate or a con artist can propose you an aqui-hire. Think about it: you have a product, skills, and you need money. They have no product, no skills, no team, no money, nothing. They pretend they may raise money, maybe, perhaps, one day, with luck, if god wishes... This is XXL bullshit. They just want you, your work, your skills, your team and your product for free. Why would you become their slave ???
