Show HN: Posting Machine – two of us running LinkedIn for 20 B2B founders

https://www.postingmachine.ai
1•_mad_eye_•1h ago
Two of us now manage 20 LinkedIn accounts using AI, and we've learned a lot about what actually goes viral.

We're building Posting Machine. We grow your LinkedIn account and find your ICPs from the people who engage with your content, so you don't have to spend time on LinkedIn doing chores like ideating, posting, replying to comments, and analyzing people's profiles.

Here's out thesis: if someone's liked your LinkedIn content, then if you reach out to them it's no longer cold outreach. It's warm outreach, and the response rate goes way up.

We don't post AI slop, because we spend a large amount of time learning what's going to work and what doesn't. And we put a lot of human care into the posts for our clients to make sure that it works.

Here's some of what we've learned about what makes content perform, from human effort and quality control:

* Career decisions: document your career pivots, they resonate because everyone's navigating transitions. * Personal stories like moving country, because they signal ambition and momentum, and you can tell them again in 6 months. * Real event sharing (conferences, launches, wins) gets amplified, because people cheer for actual momentum, not vibes. * An image of yourself will 3x impressions, and a nice personal story will 3x impressions. * What goes viral on one platform can go viral on another, and what goes viral will go viral again.

On pricing: while most content agencies ask for $3000 to $5000 per month, we price at $499/mo, with an early bird of $149/mo while we iterate with design partners.

Me and Hank both used to work at YC startups, and we have YC company founders as our initial clients. We're looking for early customers and design partners to help us iterate fast. If you're a B2B SaaS founder who values LinkedIn as a sales pipeline, we'd love to talk. And we'd love to hear what you think, especially the skeptical kind of feedback.
