That doesn't sound clear-cut at all.
Going to a C-Corp too early can be costly, moving up from a proven model LLC is easy, limits cost and risk
That doesn't sound like a good deal to me, but that's just, like, my opinion, man.
Last time incorporated a Delaware C corp it cost me a couple of stamps and filing fees. I don't remember exactly but it definitely wasn't an obscene number. The annual upkeep, including franchise tax and registered agents, is around $600.
If you're not going to have a nexus in another state (i.e. No physical location or storefront) then that's peanuts for having a corporate vehicle in the the state for corporate vehicles.
If the cost difference of a couple hundred bucks is enough to break your bank, I'd suggest finding a 9-5 job rather than incorporating.
Operational and structural details like this have always fascinated me.
I believe the original trigger for converting to a C-Corp was the Peter Thiel investment.
Most likely, you would sell the assets of the LLC to the C Corp in exchange for some number of shares (valued at the pre-money valuation of the company) and then issue additional shares equal to the VC money such that the total value of the new C Corp is the post-money valuation.
Afterwards, the founders can distribute the shares and wind up the LLC.
The alternative is for the founders to sell the LLC to the C Corp for shares and then the C Corp can wind up the LLC.
