Work With Me

Fractional Performance & Measurement Partner for Digital-First Brands

I spend most of my time leading growth and marketing internally. Along the way, I’ve found there’s a recurring set of performance and measurement problems that come up across different companies.

For that reason, I occasionally work with a small number of teams on focused projects around:

  • profit & measurement audits
  • incrementality testing and retargeting reality checks
  • ongoing guidance on how to interpret the numbers and steer growth

Who I Work With

I’m a good fit if:

  • You’re a digital-first company (ecommerce, SaaS, health tech, or tech-enabled services)
  • You rely heavily on paid acquisition across channels like Google Ads, Meta, Microsoft Ads, or other acquisition platforms
  • You feel like your platform metrics and business metrics don’t agree
  • You’re not sure which channels, offers, or campaigns are actually incremental
  • You want strategic guidance and a clear operating system, not more random tactics

I’m probably not the right fit if you:

  • Want someone to run every campaign day-to-day inside ad platforms
  • Don’t have anyone who can execute campaigns or build landing pages
  • Are looking for a “growth hack” rather than a durable way to run marketing

Ways We Can Work Together

Profit & Measurement Second Opinion

Goal: Build a single source of truth for your marketing performance and find the biggest profit leaks.

You’ll get:

Growth Scorecard
A simple, opinionated set of metrics we trust: MER, blended CAC, new vs returning mix, and a practical contribution-margin proxy.

Attribution Reality Check
Where Shopify, GA4, and ad platforms disagree—and what that means for your decisions. I’ll highlight which numbers to trust in which situations.

Tracking & Data Integrity Checklist
A prioritized list of what needs to be fixed across pixels, conversion events, and UTMs so your reporting doesn’t slowly drift out of reality.

30/60/90-Day Testing Roadmap
Concrete tests across channels, offers, and landing pages—each tied back to a specific scorecard metric (MER, CAC, AOV, payback, etc.).

This is a fixed-fee engagement (typically $2k–$7k depending on complexity and channel mix).

90-Day Measurement Reset Sprint

Goal: Turn the audit into a working system your team can actually use.

Over 90 days, we’ll:

  • Implement the core tracking fixes (or guide your team/agency to do it)
  • Stand up or refine your Growth Scorecard (Looker Studio / Sheets / Notion)
  • Align on definitions with marketing + finance (so CAC, MER, and payback mean the same thing to everyone)
  • Run 1–2 incrementality-minded tests (e.g., retargeting, branded search, or key audiences)
  • Build a simple monthly review cadence your team can keep running

At the end, you’ll have a usable “profit & measurement OS”, not just a pretty dashboard.

Ongoing Measurement & Growth Steering

Goal: Keep the numbers honest and use them to steer growth decisions—without me managing campaigns day-to-day.

Every month, I’ll:

Run data integrity QA
Check key conversion events, UTMs, revenue alignment, and explain any weird swings before they turn into bad decisions.

Own the Growth Scorecard & Executive Readout
A narrative summary of what changed, why, and what we should do about it—across channels, offers, and funnel stages.

Design and evaluate tests
Help you prioritize and design tests (creative themes, offers, landing pages, channel mix) and then interpret results using blended, business-level metrics.

Provide budget allocation recommendations
Suggest where to lean in, where to hold, and where to pull back based on profitability, not just platform-reported ROAS.

In scope:

  • Strategy, scorecard, test design, and interpretation
  • Monthly performance narrative and recommendations
  • Collaboration with your media buyers, agency, or internal team

Out of scope:

  • Building and launching campaigns
  • Daily bid/budget tweaks
  • Creative production or landing page development

You keep your existing execution muscle; I help you aim at the right targets.

How Engagements Typically Flow

Fit Call (30 minutes)
We walk through your current stack, spend, goals, and pain points. If I don’t think I can materially help, I’ll tell you.

Audit (2–4 weeks)
I get read-only access to Shopify, analytics, and ad platforms, then deliver the Profit & Measurement Audit and 30/60/90 roadmap.

(Optional) 90-Day Reset Sprint
We implement the most important fixes, stand up the scorecard, and run the first few tests.

Ongoing Advisory
Monthly retainer focused on measurement guardrails and growth steering. Weekly or bi-weekly working sessions, async Loom updates as needed, and a monthly executive summary.

Why Me?

I’ve led marketing at digital-first and growth-stage companies where the line between performance and product is thin—and results matter fast. I’ve:

  • Managed seven-figure paid media budgets across Google, Meta, and Microsoft
  • Built marketing teams and systems from scratch
  • Worked directly with product, ops, and CX to fix the full funnel, not just ads

My bias is toward clear thinking, simple systems, and decisions that C-levels can get behind.

If your team is drowning in conflicting metrics and opinions, my job is to give you a calm, defensible way to run growth.

Let’s See If It’s a Fit

If you’d like a second opinion on your numbers—or want to explore a more durable way to run performance and measurement—reach out with a bit of context:

  • Your brand + URL
  • Rough monthly ad spend
  • Main channels (e.g., Google, Meta, Microsoft)
  • The biggest question you’re trying to answer right now and what, if anything, is stopping you from getting that answer

From there, we can decide together whether a one-time audit or ongoing advisory makes the most sense.
