Mason Growth Partners

Growth, underwritten like an investment. Not a campaign.

We embed with PE-backed and founder-led companies as the operating layer for growth: strategy, media, measurement, and AI, accountable to EBITDA, contribution margin, and ARR. Senior operators in the seat, a specialist bench behind them.

Most companies don't have a growth problem. They have an execution problem.

The same four patterns show up in nearly every business we assess.

01

No clear attribution

Revenue sources are opaque. Leadership can't tell what's working and what's waste, so every budget conversation is a debate instead of a decision.

02

Stalled revenue

Growth has flatlined or reversed. The team is busy, the dashboards are full, and the numbers aren't moving.

03

No playbook

Marketing runs on instinct and tribal knowledge. Nothing repeatable survives a team change, an agency change, or a quarter of pressure.

04

Behind on AI & analytics

Competitors are running AI-native reporting, forecasting, and creative analysis at half the cost. The gap compounds monthly.

The Model

An operator-led collective. Not an agency.

Agencies sell channel management and staff it with account teams. We work the other way around: one senior operator owns your number, and a vetted network builds around the mandate.

The operator

Every mandate is led by a senior operator with 15+ years inside PE-backed, VC-backed, and public companies. In your meetings, in your accounts, accountable to the P&L.

The bench

Creative, data engineering, lifecycle, media specialists, and proven vendors, deployed only when the work demands it. You pay for output, not org charts.

The stack

AI-native reporting, competitive intelligence, and forecasting built into every engagement. The systems stay with your team when we leave.

No account teams. No juniors learning on your budget. No markup dressed up as management.

What we do.

Four disciplines, run as one system against the same P&L.

GROWTH STRATEGY & GTM

The plan that works backward from the outcome.

  • Go-to-market architecture & channel mix modeling
  • Unit economics & growth efficiency
  • Competitive positioning & market entry
  • 90-day execution roadmaps with owners
PAID MEDIA & ACTIVATION

Performance is tablestakes. The edge is upstream.

  • Google, Meta, Amazon, TikTok, affiliate, hands-on
  • CTV, programmatic, linear, OOH & audio, held to performance standards
  • Creative testing frameworks & budget pacing
  • Agency & in-house team integration, not replacement
MEASUREMENT & BI

None of it matters if the measurement lies.

  • Multi-touch attribution & marketing mix modeling
  • Incrementality & holdout testing programs
  • Tracking infrastructure & data warehouse architecture
  • Forecasting tied to contribution margin
AI & INTELLIGENCE

Build the systems. Teach the teams.

  • Predictive forecasting models for media & revenue
  • Automated reporting & competitive intelligence
  • Custom AI applications for marketing operations
  • Executive workshops & hands-on team enablement

How we engage.

Four phases, one rhythm. Every engagement is scoped against a number agreed on up front.

01

Assess

Full diagnostic of revenue channels, attribution, team structure, and competitive position. Board-ready within two weeks.

02

Strategize

The growth roadmap: channel mix, budget allocation, KPIs, and a 90-day plan with clear owners and milestones.

03

Execute

Hands-on activation across media, analytics, and creative. Most engagements show measurable impact within 60 days.

04

Systematize

Playbooks, cadences, and a team that runs the engine on its own. Every mandate has the handoff built in.

Embedded, not advisory. We sit in your meetings, own your numbers, and build things your team keeps.

Performance buys the customer. Reach builds the demand. Measurement makes them answer to the same number. AI compresses the whole cycle.

Selected engagements.

Redacted for confidentiality. Details and references available on request.

+180%

ROAS improvement · PE-backed D2C sleep brand, $50M+ rev

Post-IPO revenue decline and over-reliance on branded search. Full-funnel acquisition rebuilt, CTV and programmatic launched, and held to performance standards. Six months.

−35%

CAC while scaling spend · Menswear D2C, Series C+

CAC had doubled in 18 months on creative fatigue and no incrementality testing. Testing framework rebuilt, holdouts and geo-experiments introduced. Spend went up, CAC came down.

+12pp

Contribution margin in four months · DTC apparel

Current mandate. Measurement rebuilt from the tracking layer up, Google and Meta restructured. CM from 35% to 47% of revenue, with revenue up 23% YoY on 7% more spend.

Commercials that match the work.

Engagements are tailored to stage and scope. The structure follows the mandate, not the other way around.

Fractional & interim

CMO, VP Marketing, or VP Analytics seats on a monthly retainer. Embedded leadership without the executive search.

Project-based

Diagnostics, measurement rebuilds, channel launches, AI implementations. Fixed scope, fixed price, defined handoff.

Performance-aligned

Where the measurement supports it, we'll put fees against outcomes. If that alignment works for you, it works for us.

Let's talk about what's next.

Whether you're evaluating an acquisition, fixing a broken growth engine, or bringing AI into your operations, the first conversation is free and usually worth it.
