How to develop relationships in a new market (with no prior connections)?

Hi all,
We've been working hard on finding the right market niche to target with our offering (a cyber security product). The market we are currently trying to penetrate is community banks in the US, but we don't have real pre-existing connections there and our cold-reachout efforts are not successful so far.

Can you guys share the methods you successfully used before to develop such connections? we're not trying to sell anything yet, but instead to develop relations and get a better understanding of client problems.

Thanks!
