Important Distinctions:
- Founder: Person who started/established the company

Common Pitfalls:
- Confusing current CEOs with founders (Sundar Pichai is CEO of Google, but founders are Page and Brin)
- Not recognizing co-founders (many tech companies have multiple founders)
- Mixing up companies within the same industry group (TCS, Infosys, Wipro are separate companies)
- Outdated information about company ownership or leadership
- Confusing family businesses across generations (Dhirubhai Ambani founded Reliance, now led by sons Mukesh and Anil)
