I'm curious about your plans around open-source, since you're using it as a selling point. There's been a lot of discussion about projects that start as open-source but then go to a more restrictive license once other companies start offering their own hosted versions. Is that a concern for you?
Do you plan to include any/all of the "pro" features on the roadmap in the open-source code?
Note that they appear to have started with AGPL, which goes a long way towards preventing the kinds of uses that prominent license switches were designed to prevent.
Also it looks like they don't (yet) have a copyright assignment, which would make it exceedingly difficult to relicense if they got significant external contributions.
