I fear that my startup has sacrificed a lot of the interesting applications of our technology for the sake of revenue. Even though the business is growing quickly. I also have a meta-fear that this fear is naive.

Would you consider open sourcing your tech? That's one way to release it's value, especially when you don't have the bandwidth to capitalize on it.

think Elon Musk..

It's much easier to be a philanthropist after you have the money...

In the meantime, focus on resolving problems your customers are having.
