Business While Working at FAANG

I work at a FAANG company as a software engineer, and I also engage in entrepreneurial activities in my free time. According to my contract, without the company's approval, I cannot be self-employed or work as a contractor elsewhere. Additionally, any intellectual property (IP) created during working hours or as part of their projects belongs to them. I am not violating any of these rules.

Do I need to take any additional precautions to ensure that when my business grows, the FAANG company cannot make claims over it? Also, could this become a risk for future investors?
