How Social Growth Engineers Uses X Funnels to Grow an Email List and Promote Shortimize SaaS

Guillaume, founder of Social Growth Engineers and the viral video tracking SaaS Shortimize.com, has built a viral growth engine that turns free resources into a subscriber goldmine. His funnel is designed for speed, scale, and zero friction.

By combining visual-first tweet threads with instantly downloadable marketing tools, Guillaume is able to consistently grow his newsletter and promote his product—without spending a cent on ads.

His Viral Funnel Turns Tweets Into Email Subscribers in Seconds

Every day, Guillaume posts at least two high-performing tweet threads on X (formerly Twitter).

Each thread uses a simple format:

• Strong hook (e.g., "130M views in 100 days")

• Eye-catching visual (spreadsheet or mobile preview)

• Direct link to a gated landing page

That link leads to socialgrowthengineers.com/resources, where users can enter an email and instantly access downloadable datasets, frameworks, and tactical guides.

This builds Guillaume’s email list while directing free, qualified traffic to his SaaS product.

These Free Resources Are Built From 300M+ Viral Views

What makes the resources so compelling is that they’re not theoretical.

They're mined from real-world results:

• 130M+ Views in 100 Days: Yope Dataset — 45 TikTok accounts analyzed for viral hook performance.

• 35M Views in 60 Days: CoupleJoy Dataset — 1,500 viral videos from 12 accounts that helped the CoupleJoy app hit #4 on the App Store.

• 298M+ Views: Locket Hook Dataset — 28 accounts, 4,984 hooks analyzed.

• How-To TikTok Marketing Guides — Covers warm-up, contracts, attribution, shadowbans, and influencer pay.

There are also niche-specific datasets for creators in different verticals:

• 4,221 ChristianTok Hooks from over 3,000 Christian creators

• 8.6K StudyTok Hooks extracted from 1,000+ academic content creators

• CryptoTok, ParentTok, AstroTok, FashionTok, and other niche-specific formats are also included.

Screenshots + Data = A Feed-Stopping Twitter Funnel

Every tweet is designed for one purpose: to stop the scroll.

Guillaume pairs his threads with:

• Screenshots of real spreadsheets

• TikTok UI mockups or mobile content previews

• Download buttons that suggest immediate value

This mix of visual proof and perceived utility makes his tweets look trustworthy and actionable, boosting engagement without looking like ads.

How Two Daily Tweets Drive 100+ New Email Subscribers Per Day

Guillaume doesn’t rely on volume alone—he uses a system. Each day, he drops two new funnels.

Each one generates:

• 1,000 to 10,000 impressions

• 100 to 500 email signups

Which nets him over 100 new subscribers every day—entirely from free, organic reach.

This works because:

• He targets specific creator and app verticals

• He delivers value upfront before asking for anything

• His posts are consistent, visual, and easy to trust

This isn’t about going viral—it’s about building compounding leverage.

His SaaS Shortimize.com Gets Promoted Without Feeling Like an Ad

Alongside newsletter growth, Guillaume smartly plugs his SaaS tool Shortimize.com.

Shortimize is a tracking solution for TikTok, Reels, and Shorts campaigns. But he never sells it directly.

Instead:

• It’s linked inside the free guides

• It appears as part of the funnel’s delivery

• It’s subtly mentioned on landing pages

That way, the audience comes for the value—and stays for the tool.

The 5-Part Funnel Structure That Grows Everything at Once

Guillaume’s approach succeeds because it’s designed for speed:

• Tweet ➝ Click ➝ Email ➝ Value

There’s no fluff, no pitch upfront, and no delay.

The structure looks like this:

• 2 tweet threads daily

• Strong visuals and hooks

• High-utility gated content

• Passive but intentional product mentions

It’s a framework that builds brand, audience, and recurring revenue—all in one motion.

And it’s something any serious creator or founder can replicate.

Wait till you realize only 5 moderators control 92 of Reddit’s top 500 subreddits.

This makes so much sense. Interview Coder blew up because of the backstory of the founder.

Since anti-trust lawsuits are in action for companies with monopolies like Google and Microsoft, they can't directly buy startups but they can hire the smartest people for absurd amounts of money.
