About us

Operators first. Marketers second.

We've run the P&L, hired the team, and lived through every stage of scale. That's the lens we bring to your account.

Matthew Zielinski

Operator · Brand-side CPG
Scaled at $1M $100M $1B

Matt has spent his whole career on the brand side of CPG, at Nestlé and Kimberly-Clark. He's worked on $2B brands, managed $2B businesses, and built $0-revenue startups, so he knows what it takes to scale and the biggest problems at every stage, whether you're at $1M, $100M, or $1B.

Most recently he built Made Good's entire digital infrastructure from zero. They just bought their equity back from private equity at a $1B valuation. Along the way he's worked across L Catterton and Apollo portfolio brands.

Barry Azam

Operator · Amazon
4 exits (8 & 9 fig.) $100M+ managed 7,000+ SKUs

Barry has been part of four brands that exited for 8 or 9 figures, as the primary manager of their Amazon accounts. He managed $100M+ on Amazon for Canon, and launched and single-handedly ran the entire e-commerce channel at Leviton Manufacturing (7,000+ SKUs).

He helped take starter brand Lucky & Me from $0 to $2M in two years, has recovered $3.5M in Amazon fees for sellers, and reinstated an account in 30 days that had been suspended for two years after multiple agencies failed. He handles relationships with Amazon Vendor Managers in the US, UK and AU, and covers every part of Amazon: operations, P&L, PPC, AMC, forecasting, and product development driven by Amazon trends.

Hear it from operators who saw the numbers move.

No scripts, no studio. Founders on their phones telling you what it's like to work with us.

"Right out of the gates he brought a lot of value. He found where we'd been double-charged in Vendor Central and clawed that money back, then built the forecasting our supply chain, advertising and accounting teams all work from. I would not hesitate to recommend him."

"There's a lot of agencies that know the ins and outs of Amazon, but very few that also know how to market on Amazon. Highly recommend."

Why we exist

Tired of agencies that spend your money
without understanding your business?

Financially healthy growth. No frustration, no cookie-cutter presentations. Just operators who've built businesses and know what a healthy P&L actually looks like.

✕ The agency playbook

Spend more. Report revenue. Repeat.

Most agencies get paid on ad spend — so guess what they always recommend? They'll push budget without ever asking about your cashflow, your margins, or whether the "growth" is actually making you money.

  • ✕
    Forcing ad spend for topline revenue — and their own commission
  • ✕
    No idea what your cashflow or P&L looks like — and no interest in asking
  • ✕
    The same cookie-cutter monthly deck, every month, for every client
  • ✕
    ROAS screenshots that hide shrinking contribution margin
  • ✕
    Zero thought for how you actually build a sellable business
✓ The operator way

We build around a healthy business.

We've run our own P&Ls, sweated our own cashflow, and built brands to exit. So we grow yours the way we grew ours: profitably, deliberately, and with the end goal in mind.

Profitability monitoring

Contribution margin tracked alongside every campaign — not just topline revenue.

LTV analysis

We know what a customer is worth before we decide what to pay to acquire one.

Careful ad spend

Budget scales when unit economics earn it — never to pad a commission.

5+ companies we've helped get acquired. Healthy books, clean growth, real enterprise value — that's what buyers pay for.

FAQs

Learn more about our approach.

Which clients see the best results? +

DTC eCommerce brands spending $5K+ monthly on ads who are ready to scale on TikTok Shop and Amazon. With $200M+ in digital sales experience across similar businesses, we know how to cut waste and fuel growth in your category.

How soon can I expect to see results? +

Most engagements show meaningful efficiency gains in the first 30 days. Real revenue lift compounds across 60–90 days as creative testing, attribution modeling, and category expansion stack on top of each other.

Do you require long-term contracts? +

We need 6 months to make an impact and offer discounts for brands that lock in for 12-month contracts. We're humans — if performance isn't adding up, we'll tell you why and whether we can or can't fix it. Hasn't happened yet.

How do you measure success? +

Profit, not vanity ROAS. We model contribution margin, LTV, and incremental lift — then optimize against the metrics that actually move your P&L.

What platforms do you work with? +

TikTok Shop (creator seeding, GMV Max, live shopping), Amazon (Sponsored Products / Brands / DSP), and Shopify. The strategy connects them rather than running in silos.
