Suggestion for go-to-market: if you haven’t already done so, try to sell this direct to universities. They are an absolute pain to deal with, but they have various obligations to show how they are supporting dyslexic students etc and this fits the bill perfectly.

Their lead times are long so I’d start establishing trials now, partner with a university on agreement of a discount and use them to develop the software.

Once you’ve got a few uni’s onboard, you can rapidly expand and they are very unlikely to churn as you’re serving such an important niche.

I know a very similar product that has had huge success doing this.
