I hope no startups learn that lesson, but instead hone their products with quick turnaround from users and then when they have achieved marked fit then offer to sell their product to enterprise companies for a massive fee. And by package I mean they deliver some servers with Kubernetes on it and run the same software they run in the cloud.

If a startup tries to sell to the enterprise they are likely to die before they make enough in sales and enterprise concerns (such as on prem >> price) aren't usually shared with normal businesses.

Not saying you can't make a fortune selling overpriced products to large companies (hello Oracle) but it isn't a game for a start up.
