What is GradBro?

GradBro is a college admissions platform that helps high school students go from fuzzy thoughts to polished college essays. It offers AI-powered writing tools — ideation, editing, and review — that walk students through every step of the personal statement process.

The customer persona is clear: stressed high school juniors and seniors applying to college, looking for tools to help them write standout essays without hiring a $5K admissions consultant. GradBro's audience lives on TikTok — but the founder had no time, no team, and no desire to be on camera.

So he created a fictional high school senior, pointed Ghostfeed at it, and let the algorithm do the rest.

30 videos. 3 months. 107K+ plays. Every video AI-generated. This is the full breakdown.


The Persona: @gia_sugars

Brand accounts don't work on TikTok. The algorithm rewards personality, not logos. So instead of posting as @gradbro, the founder built AI personas — fictional students navigating admissions in real time. The kind of people who would use GradBro.

@gia_sugars is the primary account — 30 videos, 107K+ plays, and a bio that links straight to gradbro.com.

@bella_tonypony is the second persona — a different face, same playbook. She documents her college application journey with a more intense, fast-talking style. Already generating traction with the same zero-effort workflow.

These are just two of the AI UGC creators available in Ghostfeed's model library. Each persona has a distinct look, voice, and vibe — so you can run multiple accounts without them feeling like the same person. The founder picks a face, sets a content angle, and Ghostfeed handles the rest.

The content followed a 70/30 rule: 70% pure niche content (admissions takes, memes, relatable moments), 30% soft GradBro mentions. If every video is a pitch, nobody follows. Build trust first, then the mentions carry weight.

Every single video was generated with Ghostfeed's Video Cloner and Hook + Demo tools. No filming. No editing. No human on camera. Total time: about 30 minutes per week per persona.


Niche Content: Building the Audience

These videos had zero product mentions — pure value, pure relatability. The algorithm pushed them because people engaged genuinely.

What stands out: The top video hit 47.8K plays with no product mention at all. The "holy grail" video got 134 saves on under 10K views — a 1.4% save rate. "Save this" CTAs in captions consistently outperformed other hooks.


Product Mentions: Converting the Audience

These videos name GradBro directly — as testimonials and feature breakdowns. Fewer plays, but much higher intent signals.

What stands out: The "GradBro saved me" video drove more signups than the 47K niche video — 58 shares and 73 saves means people were actively passing it to friends. The arch builder video got a 3.2% save rate on just 897 plays. Low reach, high intent.


The Credibility Hack: Mention Competitors

Here's the counterintuitive move — @gia_sugars mentions College Essay Guy and Crcked alongside GradBro. Real students use multiple tools. If she only mentioned GradBro, the account would feel like a shill.

What stands out: Acknowledging competitors like College Essay Guy and Crcked made every GradBro mention more believable. The founder's logic: "If someone searches all three tools and picks GradBro — that's a higher-quality customer than someone who was just pushed an ad."


Results & What's Next

With just 2 personas and 30 minutes per week each, GradBro hit 107K plays in 3 months. College admissions is seasonal — applications peak August through January — so the founder is scaling to 12 personas to build year-round reach. Each new account targets a different slice of the audience: the procrastinator, the overachiever, the first-gen student, the transfer applicant.

Projected Monthly Views (K)

Cumulative growth across personas — scaling from 2 to 12 accounts

12 accounts projected to reach 720K views/month by month 12

The math is simple. Each persona costs 30 minutes per week. Twelve accounts is 6 hours — still less than hiring one content creator. And unlike a human creator, the personas don't burn out, go on vacation, or renegotiate their rate. Ghostfeed makes the economics work.
