Case Studies

Proof,
not promises.

What we built, who we built it for, and what it produced. Every number below came from a named engagement — no composites, no category averages.

C4 Energy

$4M+ in 30 days — then Coca-Cola acquired them.

The challenge

A high-potential brand without the digital infrastructure to match its ambitions. Instagram was underperforming, the sales funnel was not systematised, and organic outreach was manual and inconsistent. They needed systems, not more ideas.

What we built

Over a three-year engagement: complete product and sales funnel architecture, Instagram automation and DM systems, and organic outreach tooling built to run at volume without sacrificing brand quality. In parallel, 30+ influencer and celebrity collaborations producing 100+ viral videos.

  • $4M+ZBJ-attributed revenue in the 30 days before acquisition
  • 1,000xincrease in engagement and reach
  • 100+viral videos produced
  • 30+influencer and celebrity collaborations

They 10x’d our engagement the first week of us working together and the rest has been history. The most transparent and easiest agency to work with, hands down.

The systems ZBJ built stayed in active use more than two years after the engagement formally ended.

Abundance

$2M+ in under 90 days, and the category’s drop-off never came.

The challenge

A TikTok Shop coaching and commerce platform in a category with a predictable failure mode: revenue spikes on launch day, then falls 70–80% within days as momentum stalls and operational gaps surface. They needed to launch aggressively and sustain it — without pulling founders Anna and Mario into every fire.

What we built

A full-stack commercial operation: social plan, a complete ad team, high-converting funnels, and AI automations wired into the sales motion. Plus custom applications for the sales team with real-time tracking, no subscription dependency, and a 24-hour turnaround on requests. Strategies were recalibrated to the current TikTok algorithm rather than templated from past playbooks.

  • $500K+revenue in the first week
  • $2M+revenue in under 90 days
  • 9 daysconsecutively at $50–100K in daily revenue
  • 0%of the 70–80% post-launch drop-off the category expects

They were astounded by how many problems were handled without ever escalating to them.

Still a live client. Current work includes a new custom application being built for them.

1,565 to 27,953 subscribers — in a niche that doesn’t hand them out.

The challenge

The channel had existed since 2015 and sat at 1,565 subscribers in March 2026 — a flat line. Venture capital and finance is one of the hardest niches on YouTube to break into: a sophisticated audience, heavy competition, and an algorithm that gives generic content nothing.

What we built

A format and title strategy built around access rather than advice — putting the viewer inside rooms they can’t otherwise enter. Thumbnail direction, a shorts-versus-long-form playbook, and monthly analytics that separated reach from return, so budget followed the formats that actually converted viewers into subscribers.

  • 27,953subscribers, up from 1,565 on 3 March — 20,000 of them inside three months
  • 952,325views, on high-RPM finance inventory
  • 54,000hours of watch time
  • $5,175AdSense revenue — monetised in the first month
  • 402,104views on the breakout: “Inside a $750m private dinner with startup CEOs in NYC”

Roughly an 18x subscriber base in five months, from a channel that had not moved in nine years.

Meta Ads Manager reporting for the Dynasty Sports campaign: 120 website purchases at $4.01 each on $480.64 of spend, and a lifetime purchase ROAS above 31x

Dynasty Sports

$0 online to $15,000+ in seven days — at 31x on ad spend.

The challenge

A Philadelphia sports memorabilia and custom framing retailer whose entire inventory lived in glass cases inside shopping malls. Signed pieces, framed jerseys, exclusive apparel — genuine collector demand, and no distribution beyond whoever walked past that day. Online, the business was doing nothing. The stock was already paid for and already sitting there; it simply had no way to reach anyone who wasn’t in the building.

What we built

We took the in-store inventory to market online: merchandising built around the pieces that actually move, creative shot from the cases themselves, and a paid acquisition campaign aimed at collectors across the Philadelphia metro rather than sprayed nationally. Then we let the money follow the evidence — a $50/day budget, every purchase tracked to the ad that produced it, and scale released only against verified return.

  • 31xreturn on ad spend, Meta-attributed
  • $15,000+collected in the first 7 days, from $0 in online revenue
  • $480.64total ad spend behind it
  • 120purchases, at $4.01 cost per purchase

The panel above is the campaign’s own reporting, unedited — still active, and still flagged high performing by Meta, when these numbers were pulled. Inventory that had only ever sold to foot traffic now sells while the store is closed.

Different sizes, different categories, same method: build the machine, then let spend follow what it proves.
