Depends on where you live (Albuquerque, NM is not equal to NY), but that’s roughly the annual salary of a professor at a tier 1 US university. Now, I doubt that any fintech dev has an equivalent amount of work to do and the necessity to live near the expensive campus. So the actual salary you need for a living with this type of job is 50-60k. Therefore, 300k startup capital for a team of 3 people is a lot even in the US.
