TL;DR

Posting on LinkedIn is easy. Staying consistently engaged is the grind, and founders were spending hours a day replying to comments.

We built ReachSocial: a GPT-powered system that writes comments in the user's brand voice, plans 30 days of content and reports on engagement.

The MVP launched in 10 days with 30+ paying customers on day one, and users see 3× post impressions and save 10 to 15 hours a week.

ReachSocial started inside a private network for high-growth founders, with a growth marketer's message: “I'm spending 2 hours a day just replying to comments.” The answer was “We can build this.”

ReachSocial helps founders, creators and executives stay visible on LinkedIn without burning out, powered by AI agents that sound like the user.

The challenges

LinkedIn engagement is the hidden tax on your time. Posting is not the hard part. It is the 80% of work that comes after.

1. Engagement does not scale by hand

Most founders, creators and execs give up, or outsource to VAs who don't sound like them.

2. Hacks break down

Pods, scripts and hacks don't scale as soon as life gets busy.

3. Engagement drives results

Engagement is what drives reach, connections and leads, but doing it manually is not sustainable.

What we built

1. How it works

Connect a LinkedIn account, paste the link of the post to promote, and comments and reactions start arriving. Weekly 360 engagement reports give a complete view of activity.

Form titled 'Promote your LinkedIn post' with fields for LinkedIn post URL, post content launching a feature with automated comment prompts, and comment prompts suggesting congratulating the team and sharing experiences, with reaction icons of thumbs up, clapping hands, and a heart.

2. Comments that don't sound like a bot

A GPT-powered system writes comments the way a real person would, replying to post content in the user's brand voice. Setup needs no training: connect the account and it starts working. A roadmap generator plans 30 days of content from a few questions, and every comment requires approval and complies with LinkedIn's guidelines.

3. Product evolution

•Phase 1: an MVP Slack app launched in 10 days, with 30+ paying customers and over $10K MRR on day one.
•Phase 2: a dashboard with AI brand voice matching, comment generation, settings and engagement history.
•Phase 3: a Chrome extension with automated reporting on comments, reactions, profile views and messaging.
•Phase 4: weekly iteration, including dashboard analytics, agency accounts and emailed weekly reports.

Seamless experience, ReachSocial is easy to use and customizable which helps a lot! Love that you can add custom instructions to specify exactly what you're looking for.
