   has any software project successfully implemented a dual licensing model with a source available individual license and a paid commercial license?
   do we have any real examples of this?

     @haskal When you download GitLab you get the whole open source + source available code base, but out of the box the source-available part will only run with a license file. So it's close but not quite there, no official trial mode.

     @haskal Arguably the Commons Clause-derived and SSPL-like licenses are this.
     
     It's source-available for general use and if you're not SaSSing it you can pretend it's open source.
     
     MongoDB and Redis Labs modules do this and I believe they're both offered free of charge as long as you satisfy the restriction on Freedom Zero.

     From the same article, Elastic has restrictions on freedoms Zero and One, you explicitly are not licensed to mess with their licensing check.

     Actually the article brings up MariaDB MaxScale that forms part of the Enterprise offering I mentioned as a non-answer above. The website doesn't give you binaries, but the source is publically available and allows you limited commercial use. So that's a positive answer to your question.
     
     The BSL is also interesting as it has a sunset clause that limits the restrictive condition to four years, after which the source is automatically licensed under the designated open source license.

     Finally the article mentions CockroachDB and Sentry, which use BSL and grant an SSPL-like restricted Freedom Zero.
     
     I don't know which of these actors have "successfully implemented" source-available for individual use, but as far as I know they're all still going concerns a few years after they adopted it. I'll leave it to someone else to find their income statements.
     
     I admit they all skirt closer to open source than I had previously realized. Everyone except Elastic offers freedoms 1, 2, 3 and restrict 0 and the BSL projects in particular fall back to open source after some time, which makes those freedoms actually relevant for the open source community.
