A software business registered in Ukraine as an individual entrepreneur (FOP), building its own products and taking on development work in the same areas.
The interface, the service behind it, the database and the deployment come from the same place, so nothing is lost in a hand-off between teams.
One address, answered by the person writing the code. No ticket queue and no account manager in between.
The products here are not handed over and forgotten: the servers, the releases and the support for them belong to the organisation.
