TL;DR

With the LinkedIn Spyer, you can automatically track every person who engages with someone else’s posts (e.g., a competitor, influencer, or partner) and turn them into followers or even leads. It works continually with weekly updates and lets you send connection requests or DMs on autopilot.

Why the LinkedIn Spyer Exists

Let’s face it—your competitors are doing the hard work for you. At least the ones that are bigger (or better 🤣) than you, right?

They’re posting great content (160 LinkedIn Post Templates) from different profiles in their team, most of the time, the CEO and/or the founders. They’re building engagement. They’re creating audience trust.

And meanwhile… You could just plug into it.

With the Spyer, you “listen” to their LinkedIn profile every week, and ReactIn automatically scrapes new people who liked, commented, or interacted with their posts.

You can then run outreach to those people (invite only or invite + DM campaign types) without doing anything manually.

Real Example: Growing an English-Speaking Audience via Hormozi’s Posts

We’re a French SaaS team.

We wanted to grow a new audience in the US.

So we used the Spyer on Alex Hormozi’s LinkedIn profile.

Result? Every week, ReactIn scraped people engaging with his content and added them to our list. Then we sent invites to build our audience in the US, on autopilot.

No ads. No posting. Just pure, recurring audience capture—leveraging someone else’s influence. Those people will probably start to see our content, too.

Spyer Setup in 3 Steps

Step 1: Create a Spyer SmartList

• Sign up on ReactIn: Start here

• Go to the “Lists” section

• Click on “New List”

• Choose “The LinkedIn Spyer”

• Paste your competitor’s LinkedIn profile URL

• Click on “Save”

• Rename your list for easier tracking later (e.g., "Spy on Alex H.")

🔁 The Recurring Toggle is automatically ON—this is a weekly scraper.

📦 ReactIn now tracks all new post interactions from that profile every week, on autopilot.

Step 2: Launch a Campaign

• Go to the “Campaigns” section

• Click on “Create Campaign”

• Name your campaign (e.g., “Outreach Alex H. fans”)

• Select your SmartList (e.g., “Spy on Alex H.”) to feed your campaign with leads

• Choose your campaign type:
  → Invite only (recommended for this Spyer use case)
  → Invite + DM

Once selected, you can customize your campaign:

✅ Add filters (e.g., Is B2B = True, if using AI Smart Columns)
✅ Add multiple LinkedIn accounts for sender rotation
✅ Choose to send on weekends or weekdays only
✅ Set a delay between the Invite and the DM (if applicable)
✅ Skip leads who were already messaged in another campaign

💬 If you chose Invite + DM:

• Write your main message template (use variables like {{First Name}}, {{Job Title}}, etc.)

• Set a fallback message for leads missing variable data

➡️ Click “Save”, then “Start Campaign” — and you're live 😎

Step 3: Let it Run

• Every week, ReactIn scrapes new leads from your tracked profile

• It automatically filters out 1st-degree connections

• It sends invites and/or messages based on your setup

Pro Tip 💡

You can spy on influencers, partners, and even competitors’ founders. It’s the easiest way to build the exact same audience without creating content.

Why It Works (Better Than Manual Scraping)

❌ No manual scraping of posts
❌ No checking notifications
❌ No need to know which post performed
✅ Just track a profile once and let it roll
