The 5 companies (you didn't know but) are owned by Nvidia

Nvidia currently adopts a strategy focused on investing in emerging companies in the Artificial Intelligence sector, rather than making direct acquisitions. This approach allows the company to expand its influence in the AI ecosystem without taking full control of other organizations. Only in very rare cases does Nvidia choose to proceed with full acquisitions. The article mentions that there are some examples of these acquisitions, although it does not detail them, suggesting that the company prefers to maintain partnerships and strategic investments rather than traditional acquisitions.
