Sure, as a general rule, but conversions from LLCs to C corps can get very complicated as well in short order, especially when there have been different types of equity issued to founders/employees (e.g. profits interests, convertible notes, etc.). If the cap table is sufficiently large, it can cause ballooning legal costs pretty quickly. Not outrageously so, but companies can expect at least a few thousand to get added to the bill.
This is exactly the part of the process that the first iteration of Gust Launch solved. All the paperwork for incorporation and company formation are streamlined and pretty easy to fill out, and included in the monthly cost. So conversion is much, much more expensive.
The subscription cost isn't for the incorporation and formation. Being a Delaware C-Corp is just a prerequisite for users, so we include it as the first step.
