syndicator.net
A name that describes a role rather than a product survives changes in what the business actually sells. This one names a role in two separate industries.
In media, the syndicator licenses content to multiple outlets: columns, comics, wire stories, television formats. Syndication is how a great deal of content reaches audiences and the model adapted to newsletters, podcasts and video without much difficulty.
In finance and real estate, the syndicator assembles investors into a deal. Real estate syndication has grown substantially as a retail-accessible asset class, with platforms, sponsors and a compliance apparatus around it.
Either way it suits a content licensing platform, a distribution service, an investment platform, or a directory of sponsors and deals. The .net reads as a network, which is literally what a syndicator operates.
One word, agent noun, no plural problem.
