How a Pet Products Founder Runs Marketing Like a Team of Five
Brian Zibricky built Pup Stack around a portable dog anchor you can use anywhere. Dex, his Cirrius Executive Agent, cut his weekly marketing time by 80% and turned Pup Stack’s marketing into an organized, repeatable system.
The Challenge
Brian Zibricky founded Tiny Pup LLC after looking for a product that didn’t exist: a portable dog anchor you can use anywhere, on any surface. After a lot of hard work and fine tuning, the Pup Stack was born. Like most founder-led consumer brands, growth depends on constant marketing: video content, social posting, campaign follow-through. All of it competed for the same scarce resource: Brian’s time.
The Solution: Meet Dex
Cirrius set Brian up with Dex, a personal executive AI agent built on a Claude harness. Dex is not a chatbot or a one-off automation. He is a persistent teammate who knows Pup Stack’s business, keeps organized context across sessions, and executes real work.
Within weeks, Dex became the operating hub for Pup Stack’s marketing:
Before Dex: 10 hours a week. With Dex: 2
8 hours a week, every week
Dex absorbs work that would otherwise need added headcount
With Dex, Brian’s marketing time dropped from 10 hours a week to 2, an 80% reduction that returns more than 400 hours a year to growing the business. The added capacity has saved Pup Stack at least one hire.
- Marketing organization. Dex structures Pup Stack’s marketing activities into a coherent, prioritized system, so nothing depends on what Brian happens to remember.
- Social media publishing, three times a week. Dex builds the context, imagery, and messaging, then posts across Pup Stack’s social platforms. Brian’s only step is a quick validation pass before it goes live, so a consistent cadence no longer depends on how much founder time is available.
What’s Next
Brian is now expanding Dex beyond marketing:
- Financial analysis. Dex will analyze Pup Stack’s revenue and financial performance to surface where growth is hiding.
- Continuous learning loop. Dex observes what works, captures it, and improves, so the agent gets more valuable every week it runs.
Before Dex, too much of Pup Stack’s marketing lived in my head—and execution depended on whether I had enough time to get to it. Dex has helped turn that into an organized, repeatable system. He understands the business, retains the context behind our decisions, and can move real projects forward without me having to start from scratch every time. For a founder, that kind of leverage is incredibly valuable. It feels less like using another AI tool and more like adding a capable teammate who gets better the longer we work together.

The Pattern
Pup Stack is what the Cirrius Executive Agent offering looks like in practice: one founder, one agent, and a business that suddenly operates with the consistency of a much larger team. You borrow the expertise. You build the asset.
