Fractional growth leadership for DTC brands scaling past $10M.
Embedded as your fractional Head of Growth. Built around profitability, not platform-reported ROAS.
The growth questions get harder past $10M.
The platform dashboards still look healthy. Blended CAC has crept up. Payback periods have extended. The math the platforms report isn’t matching the math in your P&L.
You’ve added channels, tools, and agencies. Topline is up. Margin is not.
You need senior growth leadership. The agency model isn’t making strategic calls, and a $250K VP of Growth hire is hard to justify before the next stage of the business.
A meaningful chunk of your paid spend may not be incremental. You’ve never had the bandwidth to test for it directly.
How it works.
I embed with your team as your fractional Head of Growth. The shape of the engagement adapts to where senior leadership matters most.
Ownership of the full growth function. Work focused on a specific channel or measurement gap. Pressure-testing the assumptions in your current acquisition system. The edges of the engagement get drawn around the problem, not a tier sheet.
Across every shape of engagement, three things hold.
Decisions against contribution margin and payback period.
Not platform-reported ROAS. The math the dashboards run on is the math your CFO would recognize.
Channel calls run on incrementality.
Geo holdouts and matched-market tests answer the harder question — whether spend is incremental at all — instead of last-touch attribution moving the budget.
Built to be handed back.
The dashboards, test roadmap, and measurement stack built during the engagement stay with your team when we’re done.
Run your growth on math your CFO would recognize.
A 30-minute call. No prep needed. You’ll leave with sharper thinking on your growth math whether or not we work together.
Built by an operator that’s been there.
I’m Andy Jeong. Most recently Head of Growth Marketing at Aviron (YC W21), where I joined at seed stage as the first marketing hire and built the growth function from scratch. Over four years, revenue grew ~34× alongside a successful Series A raise.
I led a cross-functional growth team across performance marketing, experimentation, and web optimization, anchored by an incrementality measurement program across Meta, Google, and CTV using geo holdout tests, media mix modeling, and propensity modeling. Platform-reported metrics were replaced with internally trusted signals that budget allocation and forecasting could actually run on.
Seed Growth is the consultancy version of that same operating discipline.

We’ll cover what you’re trying to grow, what’s working, and where the measurement is letting you down.
If there’s a fit, you’ll leave with a recommended next step. If not, you’ll leave with sharper thinking on your growth math either way.
