Financial Models?

Depends what you're looking to do, but the short answer is there are plenty of free excel templates online for every business model imaginable. Remember that a financial model is a digital copy of the business and it should serve 2 purposes: save time and simplify/make better decisions. Obviously, you will trade away some decision making power if you use a generic/free template, but you can always add customizations later. I am working on a youtube channel focusing on financial modeling for entrepreneurs so feel free to send me what you have if you want free feedback.

Can you get into more detail as to what you're looking for?

Do you want to write a business plan? Do you want to do forecasting? Have you already started your company?
