What is a fractional head of growth?

A senior growth operator who works part-time across strategy and execution, without the cost of a full-time executive hire.

How is this different from a marketing agency?

Agencies usually execute channels. Growth architecture decides which channels and product changes matter, then the same operator builds them.

Who does the growth architecture work?

The operator who scopes the work does the work. No hand-offs to junior teams.

Do we own everything?

Yes. Code, content, accounts, and data stay yours with zero agency lock-in.

Strategy & Context

Growth Architecture

One growth plan across product, marketing, and distribution. A fractional head of growth approach for teams that need direction and execution from the same person.

In short

What this capability does

Growth architecture is a single, prioritized growth system that connects product, marketing, and distribution to one north star metric. Cantellis designs it as a fractional, operator-led engagement and then executes the first bets, so strategy never sits in a slide deck.

Our point of view

Growth is a system, not a list of tactics.

Most early-stage teams do not have a growth problem. They have a sequencing problem. Ten good ideas run at once, none get enough attention to work, and the team concludes that growth is hard. The fix is rarely more activity. It is a model that shows which input actually moves the north star, and the discipline to work on that input first.

We treat growth architecture like product architecture. There is a core loop, a set of inputs, and dependencies between them. Content cannot convert if positioning is unclear. Paid traffic burns money if the landing page leaks. Retention work is wasted if activation is broken. Mapping those dependencies is what turns a roadmap from a wish list into an order of operations.

The second shift is ownership. Strategy written by one party and executed by another loses most of its value in the hand-off. When the person who models the growth system also ships the first experiments, assumptions get tested in days and the plan improves with every release.

Critical signals

You likely need this if

01
Nobody can name the one metric that matters this quarter
02
Marketing and product priorities are set in separate meetings
03
Experiments end without a documented decision
04
Growth depends on the founder doing everything manually

The problem

What this solves

We turn the underlying constraint into a focused body of work, rather than treating surface symptoms in isolation.

01
Channels and experiments run without a shared north star.
02
Product, marketing, and sales pull in different directions.
03
Growth ideas pile up but nothing gets prioritized.

Common use cases

Where this capability earns its place.

Post-launch startups with no growth owner

Founders who shipped a product but have no head of growth get a clear model of where users come from and what to fix first.

Boutique agencies scaling their own pipeline

Agencies busy serving clients get a repeatable plan for their own inbound, referrals, and productized offers.

Product teams with scattered experiments

Teams running many small tests get one backlog ranked by expected impact and effort.

What you get

Deliverables

North star metric and growth model
Prioritized 90-day roadmap
Experiment backlog with hypotheses
Measurement plan and dashboards

How it runs

Our approach

Diagnose

Review analytics, funnel, positioning, and channels to find the real constraint.

Model

Define the north star metric, input metrics, and a simple growth model everyone can read.

Prioritize

Score bets by impact, confidence, and effort into a 90-day roadmap.

Ship the first bets

Build the highest-leverage experiments directly, with tracking in place before launch.

Lovable and Claude

Excellence at speed

AI is the accelerator, not the product. One operator keeps strategy, build quality, and business context connected.

01
Claude synthesizes interviews, reviews, and analytics exports into themes in hours instead of weeks.
02
Lovable turns roadmap bets into working landing pages, calculators, and tools in days.
03
Every assumption is written down so AI output is checked against real data, not trusted blindly.

Expertise and outcomes

Capability that changes the work.

Pillar-cluster and AI search growth programs
Funnel and GA4 measurement design
Hands-on product building on Lovable

Expected outcomes

One shared growth plan the whole team understands
A ranked backlog instead of a wish list
Measurable experiments live within weeks

What we see go wrong

Common mistakes to avoid.

Copying another company's playbook

A tactic that worked for a venture-funded SaaS rarely transfers to a boutique agency. Context decides what works.

Choosing a vanity north star

Traffic or followers feel good but rarely predict revenue. The north star should track delivered value.

Running experiments without hypotheses

If you cannot say what you expect and why, you cannot learn from the result.

Planning more than you can ship

A 90-day roadmap with forty items guarantees partial progress on everything and impact on nothing.

Measurement

How we measure success

North star metric: The single measure of value delivered to customers
Input metrics: Two to four drivers you can influence weekly
Experiment velocity: Tests shipped and decided per month
Pipeline contribution: Qualified opportunities traced to growth work
