How do I get access to the TileDB marketplace feature? It says it’s in beta, and I cannot find it anywhere.
Is it available for individuals, or only for organizations?

To access the tile db marketplace feature, which is currently in beta, you need to request access directly from TileDB. Visit their official website and check for a dedicated marketplace section or a contact form where you can express your interest email their support team to inquire about eligibility and the onboarding process.
The marketplace is primarily designed for organizations, but individuals may also gain access, depending on specific use cases and requirements.
