Getting started on realizing your product vision or getting your startup off the ground can be difficult without seed capital or sales revenue. Outfitting developers with professional level tools can be cost prohibitive before you have product to sell. So the Delphi Starter Edition is both designed and priced to allow individuals and startups to bootstrap their vision until related revenues reach $1,000 at which point a specially priced Professional Edition license can be purchased.
So, if you’re an individual you may use Starter Edition to create apps for your own use and apps that you can sell until your revenues reach $1,000 per year. If you’re a small company or organization without revenue (or up to $1,000 per year in revenue), you can also use the Starter Edition. Once your company's total revenue reaches US $1,000, or your team expands to more than 5 developers, you can move up to an unrestricted commercial license with a specially priced Professional edition license. See the Starter Editions FAQs for additional details.

Yo creo que la idea no es mala.
Si empiezas un negocio, es lógico que no puedas o quieras desenbolsar una gran cantidad de dinero; Te ofrecen una versión con la que puedes crear programas y venderlos. Y si la cosa va bien y ganas dinero ya cambiarás, sino, el desenbolso a sido mínimo.
Parece que la restricción es el dinero que ganes y el número de empleados.
