Vendors Similar to Kerafast

 Does anyone know of any companies or platforms that are similar to Kerafast? Or is this a one-of-a-kind vendor?

http://www.kerafast.com/

Specifically, I am wondering if there are any other companies that buy or facilitate selling materials produced by a lab and give a cut of the profits to the lab?

Thanks.
