VP of Marketplaces & Growth
I scale brands profitably
and build the tools
to enable it.
I turned a money-losing marketplace business into an 8-figure acquisition. Before that, I found $7.2M in wasted ad spend hiding in plain sight. The difference between me and most growth marketers and e-commerce consultants: I build the software that makes it repeatable.
About
Most e-commerce leaders optimize. I rebuild the engine. At BirdRock Brands, I inherited a business bleeding margin on every order — no item-level profitability, no bid logic, no data infrastructure. I built the team, built the systems, and drove a full turnaround that led to an 8-figure strategic acquisition. That's the kind of operator I am: I don't just set strategy — I hire the people, build the infrastructure, and stay until the number moves.
I've launched brands from zero to seven-figure run rates on Amazon and DTC in under 12 months, and helped several grow from seven to eight and even nine figures in revenue — profitably. The common thread: building high-performing cross-functional teams, obsessing over unit economics, and creating systems that compound.
The thing nobody expects: I write production software. Not dashboards-as-a-hobby — three full SaaS applications with 1,500+ automated tests, data pipelines processing 3.5M ad targets nightly, and an AI agent system with 50+ autonomous skills. When I see a manual process costing a team 10 hours a week, I don't hire — I ship code.
I work best with founders and operators who are tired of agencies that can't explain where the money went. If your marketplace business has more potential than your current strategy can unlock, that's exactly the gap I fill.

What People Say
Don't take my word for it
“Jack used our platform to drive $10M in sales for BirdRock in just two months, breaking all their single-day and peak season records. His understanding of the financial mechanics behind customer acquisition is exactly what brands need but rarely find.”
“Jack inherited a complex, unprofitable Amazon business and turned it into our strongest channel. His 475% margin improvement wasn't luck — it was systematic, data-driven execution. He's the real deal.”
“Jack's technical depth sets him apart. He doesn't just run campaigns — he builds systems, automates workflows, and creates tools that compound results over time. A true operator.”
“Jack took our marketplace strategy from scattered to systematic. Within months, we saw measurable improvements in both revenue and margins. He's the kind of partner who treats your P&L like his own.”
“Advising Jack on his startup showed me his rare combination of technical ability and business acumen. He approaches problems with a true founder's mindset — scrappy, data-driven, and always focused on what actually moves the needle.”
“Jack has one of the most comprehensive understandings of the e-commerce customer acquisition process I've encountered. He connects the dots from advertising spend to conversion to lifetime value in ways most marketers simply don't.”
“I had the privilege of working with Jack on the marketplace team and he played a key role in helping me improve my advertising skillset. His expertise in eCommerce is exceptional, and any team would benefit greatly from having him on board. Jack is easily one of the most knowledgeable people I've worked with in marketing.”
“What truly sets Jack apart, beyond his extensive eCommerce experience, is his savvy use of AI to streamline daily tasks and enhance reporting. His innovative approach provided deeper insights for special projects, including due diligence audits for PE firms. I can't recommend Jack highly enough.”
“His calm demeanor made it easy for colleagues and clients to work with, and his vast knowledge of ecommerce on top of his admiration for incorporating AI into everything makes him a constant value asset to any organization.”
