How to find investors for NFT startup?

Say I had a pretty solid idea and business plan for turning an existing real-world digital product into an NFT marketplace, aiming to take away market share from the existing market of that product. So it's not innovative per se, but doing this on the blockchain solves a couple of problems for both publishers and users such as decentralization, cutting out middle men, much improved user experience. It's just a much more classy implementation of what already exists, mostly offered by quasi-monopoly marketplaces. Just putting NFTs to some really good use.

How do I find funding for it? Hiring a bunch of people for one to two years until launch, office space etc, would require maybe 1 to 2 million USD.

Where can I go to find investors?

It’s for a relatively small industry, so I’m not looking for crowd-funding, as this project won’t speak to a large enough general audience. Big players inside the specific industry are also not a good place to ask, as they would be the ones getting disrupted in the end. So I'm looking for people who invest specifically in crypto ideas because it’s crypto, if the business plan is solid enough.

I'm in Germany actually, but that industry is global.
