We used Zenaton to rebuild our onboarding process for new members of our community (asynchronous emails, slack messages, and backend processes). It allowed us to build complex workflows that we would've never been able to setup on Zapier (not for lack of trying!), without adding much complexity. The interface makes it easy to track ongoing executions and be alerted when there's a failure. The team is very responsive, pushing updates often and producing a lot of content to help & inspire users. Highly recommend it!
