Hey Reese W. a few things you could consider to try
you can start with companies hiring for linkedin or paid social roles. this could be a good signal since it seems they clearly have budget and are already invested in the channel
also check if they're running linkedin ads, pull their domain into similarweb or other related tool (you can do this in clay) and see if they're running paid traffic elsewhere too. this tells you a lot about their needs and you can build messaging around what they're doing vs what's missing
and you can try out retargeting, reaching out to people visiting your site or engaging with your content - you got warm leads here. you could also run ads to that audience and layer cold email to the same people.
and if you are already running ads, you can retarget people (outreach target) who came through those ads. But qualify them based on how they behaved after clicking and their activity,
