You don't need any formal education, but it helps to have deep industry knowledge, organizational dynamics expertise, emotional intelligence, project management, venture finance, legal, and other skills. Ideally you have university education, which could come along with technology accelerator programs from your institution.
In the first few years, you are talking to as many potential customers as possible to identify pain points in a particular industry, segment of society, user group, etc. This requires a lot of initiative in booking customer discovery meetings. Then once you're on to something, you will be trying to build a founding team with the required expertise to build the product in collaboration with initial customers. Once you have a minimum viable product, you will either be trying to find investors, or finding paying beta customers, or both! Then it is endless product iteration, financing, sales, and team building.
The best part is that you have complete control over building the solution and team that you want in solving your chosen problem. It is very rewarding to be able to create something from scratch and see it come to life. You will hopefully be working with early adopter customers, who are awesome to deal with if you're an innovative and fun type of person.
Creative license to build the team and product you want to deliver to society. No bureaucracy or boss besides your family. Unlimited potential.
The downside is that the risk of failure is high, the risk of stress burnout is high, the time commitment is 24/7, and there might not be much to add to your resume at the end of it despite everything you accomplished and learned.
When you start out you don't have a salary since you're probably still developing the product. But you will have equity in the company. Ideally, you can access government grants or other forms of non-dilutive capital to pay for initial expenses, but getting a salary won't typically come until you've received venture capital or are generating revenue.
Look for unmet needs in your own life or workplace. There is probably a new technology waiting to be developed. Make sure you are extremely passionate about solving the problem. Then do as much research as possible into the subject and interview 50 or more potential customers in the first month. If you think you're on to something, build a prototype and see if you can get some initial results, then iterate until product-market-fit becomes within reach!
