I would target the segments that make sense for your project. Engage with them with genuine interest (i.e. don't try to sell your stuff). For professional networking, LinkedIn is straightforward to keep animated. With just a little automation and careful targeting (phantombuster + one month of sales navigator for extracting the initial lists) you can send 10 invites per day to people in your target network. In 10 minutes (2h on your first try) you can prep a quarter worth of LinkedIn invites. With tools like buffer, and curating other people's content, it's also simple to appear active on social networks with comparatively little effort.

It keeps the commercial pipeline full enough for me to worry about recruitment, not networking.
