Hi okolokoroM,
I used vertalen.nu/zinnen to translate your message since I don’t speak Spanish, so I may have misunderstood something from your message.
In any case to answer your query: Haiku is not sold, it is free (as in free beer).
In my experience companies when considering options want something to buy especially if the company is bigger. If you buy a license to a software you usually get a support contract.
If you want to make money with Haiku selling support could be an option, but you would need some developers to be able to actually fix problems in Haiku, integrate it into existing systems etc.
And leaving all that aside Haiku is beta software and shouldn’t be trusted with your data if you depend on it, and it’s security is very weak. (Could be “okay” for some stuff that is NOT connected to the internet, but not for connected terminals)
Sounds like a really hard sell to me. : )
