This might be different from state to state. There are also EU grants you can apply for, which might contribute to employee salaries. Those are somewhat difficult to navigate and apply for, but sometimes worth it to bridge the salary gap between a "normal" German company and FANG.
Not sure which one the original comment is talking about, but look into "Gründerstipendium" / "EXIST Stipendium".
Then there are also more scholarships based on other criteria, e.g. your state or if you are at an university, many universities also have some sort of entrepreneurial scholarship which will then also help you get the larger scholarships afterwards.
