Mediapresser reads as an agent noun: the one who does media press work. It’s a compact way of naming a PR function, a distribution service, or a person whose job is getting coverage.
The fit is press release distribution, a media outreach platform, a PR agency, a journalist contacts service, or a tool for pitching. Distribution is the most interesting commercially, since the incumbent wire services are expensive, widely resented, and increasingly questioned on whether they deliver anything.
There’s also a lighter reading, where presser is journalist slang for a press conference. A service around organising, streaming, or covering press events would suit the name equally.
Twelve letters, two recognisable components, no hyphen, .com. The -er ending makes it sound like a tool that does something rather than a category, which is the right register for a product rather than a directory.
Offers welcome.
