I have some big types of betting and casino software. where can I sell them...?

My software is much bigger and more expensive. 1 win, sports, classic, fish slot, play game pack So I have to find a clients with a bigger budget. Please help me with tips how I can find them

why you are not start selling bhw marketplace mate lot's of users already in. best wishes for you.

You are already a forum seller.
Instead of selling your software, rent it for a monthly fee.
Plenty of customers right here.

If you r looking at selling the whole casino/betstack, then my recommendation would be to go for igaming communities and B2B marketplaces rather than general software platforms =)
but
, before you go out searching for potential buyers, there is one thing that needs to be settled: is there any current integration between the software and the payment and game options, or are you selling just the code/platform? This will dramatically affect your target audience.

For those who are interested in buying rather than selling the system, I would compare some of the more popular providers such as NuxGame, KodeDice, SoftSwiss, or EveryMatrix. You will lose control, but you will save yourself from investing months in integrating games, payments, PAM, and getting licenses.
