Founder of JuiceFS here, we have spent 4 years building it and open sourced it today.
On your website you have a pricing page. Do you have much revenue?
JuiceFS is the missing piece of ML eco around MLFlow / JupyterHub. We deployed it as researcher's primary storage solution as it perfectly scale a traditional linux (uid/gid based acl) experiece to cloud OSS.
Highly recommend to any team wanna build their internal machine learning platform on cloud.
