The -er ending makes this sound like a tool that does something rather than a category, which is the right register for a product rather than a directory.
Mediapresser reads as an agent noun: the one doing media press work. It suits press release distribution, a media outreach platform, a PR agency, a journalist contacts service, or a pitching tool.
Distribution is the most commercially interesting, since the incumbent wire services are expensive, widely resented, and increasingly questioned on whether they deliver anything measurable.
There’s a lighter reading too, where presser is journalist slang for a press conference, suiting a service around organising, streaming or covering press events.
