Can't say "large" but I've been using LinkedIn for years for myself, my clients and even friends. My first company was a tech consulting firm and we generated around $600K in ARR from LinkedIn alone (the rest was upsells on exactly those deals).
Roughly speaking, in the last 6 months I've generated about 5M impressions across 3 different profiles (one is my own, one is a client and one a friend), which netted around 70 meetings approximately (I have closed nearly all of the meetings I got, can't say the same about my friend and the client but that's the next stage).
Let me know what questions you have. Happy to jam ideas and refine hooks (frankly, my guilty pleasure)
