Unity Industry Success is an upgrade to the Enterprise Success that comes with Unity Enterprise, with additional add-ons and lower seat count thresholds to access higher tiers of support.
Industry Success includes a new engagement, Product Activation, a 1-month engagement with a technical Unity resource to make sure team members get access to everything their license entitles them to.
Every seat of Unity Industry comes with a license for On-Demand Training, which includes access to 300+ hours of content on editor basics, lighting, deployment, optimization and more. In Enterprise Success plans, seats of On-Demand Training are limited and shared between an organization, and in Starter Success plans, only one course is available per license.
Unity Industry also changes the thresholds for accessing higher tiers of support and dedicated advisors - organizations with 10+ seats of Unity Industry will have access to Partner Relationship Managers (PRMs) who do regular, proactive check ins. They will also have access to Premium Support, while those limits are 20+ seats for Enterprise Success plans. Starter Success does not have access to dedicated advisors or Premium Support.
