I'm sorry for any confusion, but as an AI developed by OpenAI, I am unable to directly browse websites or extract live information from them. I can provide information based on stored data or offer suggestions on how to effectively find information. In the case of ByteDance, it would be best to look out for sections dedicated to case studies on their website. They could be housed under sections such as "Work," "Projects," "Partners," or even "News." However, for the actual verification of the case studies, you would need to browse the website yourself or use a web browsing tool.
