Which company owns Presenti AI?

I have now discovered that the redemption process is extremely tedious.

I was informed that
- Pixso.net
- BoardMix.com
- Presenti.AI
have the same login details
or
that a different email address should be used to log in to each of these services.

Communication with support is extremely poor.
Let's see if the 4 emails finally lead to a solution.

I find it irritating that you can use the same login details for 3 different services.

My research was only quick and dirty with Perplexity.
According to Perplexity, the three offers mentioned above belong to three different companies in different countries?!

Then why do all three offers have the same login details?!
