What’s the smartest way to use LinkedIn when you’re new and working at a SaaS?

I recently joined a SaaS and I’m starting to realize how big LinkedIn can be not just for “posting,” but for actually building pipeline, reputation, and connections. The problem is, I’m totally new to it.

Until now, I only used LinkedIn as an online CV. Suddenly, I see people booking calls, getting inbound, and scaling their brand just by being consistent there. Some even say LinkedIn is their #1 growth channel.

Right now, I’m stuck between two approaches:
Trying to build my own profile as a growth lever (posting stories, sharing value, building a network).
Or focusing purely on outbound (connection requests, messaging, using automation carefully).

I’d love to hear from people who have actually done it successfully: what worked best for you when starting from scratch on LinkedIn? Was it posting consistently, connecting with the right people, or building multiple avatars/accounts?

Basically if you had to start fresh on LinkedIn in 2025 to grow a SaaS, what would you do?
