Is Box part of Google?

Excuse me, could you please clarify for me if Box is indeed a subsidiary or a part of Google? I've heard some confusion surrounding this topic, and I'd like to get a definitive answer. I understand that both companies operate in the technology sector and offer cloud-based storage solutions, but I'm not sure if there's any direct ownership or affiliation between them. Could you help me understand the relationship between Box and Google, if any?
