LinkedIn posts or LinkedIn DMs: which one actually gets you paying customers?

I post on linkedin most days and send about 20 dms a day, and if I'm honest the posts mostly warm people up while the dms do the actual selling. almost nobody has bought straight off a post.

curious if that's the same for others or if I'm just doing posts wrong. has anyone got paying B2B customers mostly from content, with little or no outreach? and if so, how long did it take before it started working?
