How Do You Sell Fonts to Book Publishers?

Hi 

We are small business that improves, encourages and facilitates reading and learning. Part of it is a small foundry https://omotype.com/

We see quite good results in text legibility and readability with our OmoType Sans font. We did a couple of studies with it and get a lot of amazing feedback, especially from those kids with dyslexia and reading difficulties as it is free for personal use and for education. We sold licences to local book publishers since we have good contacts with them.

But I'm having big challenge of creating awareness to publishers globally, especially in children books section. I'm not even sure who to reach out to or on what channels to be present at.

Does anyone has experience with engaging publishers?

Cheers,

Vanja
