Whether it is better to publish your PhD thesis or have your own company (startup) depends on your individual goals and circumstances. Here are some factors to consider:

• Your research interests. If you are passionate about your research and want to continue contributing to your field, then publishing your thesis is a great way to share your findings with the world. You may also be able to use your thesis as a springboard to a research-oriented career in academia or industry.
• Your entrepreneurial spirit. If you are more interested in the business side of things and want to see your ideas come to life, then starting a company may be a better fit. You will need to be prepared to take on a lot of risk and work long hours, but the potential rewards can be great.
• Your financial resources. Starting a company can be expensive, so you will need to make sure you have the financial resources to support yourself and your business. If you are not independently wealthy, you may need to find investors or a co-founder who can help you raise the necessary capital.
• Your risk tolerance. Starting a company is a risky venture. There is a good chance that your company will fail, so you need to be prepared for that possibility. If you are not comfortable with risk, then publishing your thesis may be a more conservative option.

Ultimately, the decision of whether to publish your thesis or start a company is a personal one. There is no right or wrong answer, and the best choice for you will depend on your individual circumstances and goals.

Here are some additional things to consider:

• The potential impact of your work. If you believe that your research has the potential to make a significant impact on the world, then publishing your thesis may be the best way to share your findings with the public.
• Your career goals. If you want to pursue a career in academia, then publishing your thesis is essential. However, if you are interested in a career in industry, then starting a company may be a more relevant way to showcase your skills and experience.
• Your personal preferences. Some people prefer the structured environment of academia, while others prefer the freedom and flexibility of entrepreneurship. Ultimately, the best way to proceed is to choose the option that is right for you.
