RediSQL looks interesting and I like the pricing structure. I'm working on marketing my own set of products so I know it's difficult to keep it up. Good luck with this venture and I hope it works out for you and your team.
Please get in touch, there is my email in the profile! There is a small community of people that try to live with open source software.
If your product is somehow usable with RediSQL we could do marketing together or bundle our products, there are a lot of synergy in software that can be enhanced.
