Mastermind group for makers targeting Professional Photographers

I would like to start or be part of a mastermind group of makers who want to sell or already selling products to professional photographers.
I'm a professional programmer with 10 years of experience currently working on a product for this particular market. I'm looking mostly for influence (influencing or being influenced) and building human relationships and advice.
If you happen to know a mastermind group, please let know. If you want to participate just write a comment below, we'll figure out the rest together.
