That said, https://gust.com/launch/comparison/delaware-corp-vs-llc will give you a good idea of the trade-offs and considerations. Based on the homework we've done, C-Corp is a cost- and paperwork-competitive choice if you want to leverage equity for funding or employee incentives.
In terms of changing from LLC to C-Corp, statutory conversion is relatively straightforward especially if you structure your original LLC with future conversion in mind (choose a state that supports statutory conversion, understand how membership interest will convert into shares). I _think_ Stripe Atlas might still offer an LLC with an easy conversion path.
