Bugs can occur for various reasons, including but not limited to:
1. Human Error: Mistakes made by employees or founders can lead to bugs in processes or products. 2. Complexity: As businesses grow, their systems and processes become more complex, making bugs more likely. 3. Lack of Resources: Startups often operate with limited resources, which can result in less thorough testing and quality control. 4. Changing Requirements: Rapid changes in market conditions or customer preferences can lead to bugs if a company isn't agile enough to adapt.
