It seems like you don't want to reveal too much information to the public, but in this case it is very hard to assess the value proposition. Maybe you just need this thread to have some reference (backstory) when you hit multiple casinos with your pitch. IMO, not a good strategy, but I understand.
If you run a platform (or know someone who does), feel free to DM us or reply here. We’re happy to share more details, a playable demo or jump on a quick call to see if it’s the right fit.
We’ve developed a brand-new, original casino-style game
At least you can tell us, what is the nature of your game? Is it player vs player or a slot game variant? If you have developed a game with certain skills involved, you might be up to filling a much needed gap in the online gambling world.
Your sales pitch is pretty weak op. You are not impressing anyone with such a simple sales pitch. Do you have any idea how difficult it is to draw the attention of casinos(Big and Small) these days?
You shouldn't be the one asking them to list their platform here. Smh! Instead, you should politely request them to check your product out privately or within this thread itself. Think!

Well, it depends on the product. How good is it? But I get your point for average game developers; they should not have high hopes lol
