Fractional CMO · AI-Native Growth Operator
You built the product. I turn traction into predictable revenue.
For post-PMF AI and B2B SaaS founders stuck on a growth plateau, founder-led sales, or a messy GTM. I embed as a senior operator 1 to 2 days a week, rebuild the growth system, and hand it back to your team.
Currently accepting a small number of fractional CMO engagements for Q2 2026.

Techstars AlumGoogle for Startups — Growth MentorCambridge Judge — Visiting Lecturer You've got traction. So why does growth still feel like guessing?
Paying customers. Revenue line moving. A fundraising deck that holds up. But the acquisition engine? Growth plateauing, founder-led sales that doesn't scale, no repeatable pipeline, and a GTM stack that's three tools taped together.
You've tried paid. You've tried content. You've tried hiring a generalist marketer. Something worked, most of it didn't, and nobody on the team can tell you why.
You don't need more tactics. You need a senior operator who can walk in, see the whole system at once, and tell you, with specifics, which two levers actually matter for your company right now.

What I do
Work with me.
Three ways to work with me. Start wherever the shape fits.
Primary path
Fractional CMO
Senior growth operator, embedded 1 to 2 days a week.
I run the growth function end-to-end. Own the GTM strategy, build the systems, hire the people, and operate until you're ready for a full-time Head of Growth or VP Marketing.
Best for: Seed to Series B teams without a senior growth leader, or bridging between full-time hires.
See the engagement detailsAlso offered
Speaking
Keynotes and workshops on AI-native growth, GTM, and founder-led distribution.
Real campaigns, not recycled conference material. Founder audiences, accelerator cohorts, corporate innovation teams.
Best for: Conferences, accelerators, founder offsites, podcasts.
See speakingAlso offered
Mentoring
1:1 sessions for founders with a specific growth question.
30 or 60-minute working sessions. 388+ sessions delivered, 4.93/5 rated on GrowthMentor. For founders who need a senior outside brain for an hour.
Best for: Seed to Series A founders with a specific decision in front of them.
Book a mentoring session Fit
Who this is for, and who it's not.
I'd rather save us both a 30-minute call if we're not the right match.
Best fit
- Seed to Series B, post-PMF
- Real traction — founders already have paying customers
- Founder bottlenecked on growth decisions
- Need senior operator judgement, not junior execution
- Ready to invest in systems, not campaigns
Not a fit
- Pre-PMF / pre-revenue teams still searching for a problem
- Looking for a cheap agency to run ads
- Need a full-time FTE replaced at junior cost
- Want vanity metrics reporting rather than revenue impact
Why not an agency
Senior growth judgement, not junior execution.
You do not need another agency layer when the real problem is senior growth judgement.
A typical agency
- Junior account managers execute the work
- Long retainers, fixed scopes
- Vanity metrics in monthly reports
- Brand-safe best practice, not contextual calls
- Handoffs between strategy and execution
Working with me
- Senior operator in the seat — no junior layer
- Embedded ownership of the growth function
- Revenue-focused. Pipeline, conversion, payback
- Opinionated, contextual calls on your company
- Build the system, then hand it off clean
The method
I don't sell services. I build systems.
Most growth consultants arrive, ship a deck, and disappear. That's not how I work.
Every engagement builds the same thing, a growth system. Not a campaign. Not a funnel. A repeatable architecture your team can run after I'm gone.
6 layers, tailored to where you are
01
GTM systems
ICP, positioning, channel strategy, acquisition engine design.
02
Product-led growth
Activation, retention, freemium and trial conversion.
03
Experimentation
Prioritisation, test design, learning loops.
04
AI-native workflows
Generative and agentic AI for research, messaging, enrichment, content.
05
Founder-led distribution
LinkedIn systems, content-to-pipeline loops.
06
Revenue operations
Channel, ICP, pipeline, reporting cadence.
If "growth system" sounds vague, that's fine. I'll show you exactly what it looks like on a 30-minute audit.
Category
There's a gap between AI-curious and AI-native. Most growth operators are on the wrong side of it.
AI-curious teams use ChatGPT to draft blog posts. AI-native teams rebuild their growth stack around generative and agentic workflows, research, message testing, prospect enrichment, campaign iteration, content at scale, and ship faster because of it.
I work on the AI-native side. Every engagement I run uses AI to cut execution time on the work that used to eat weeks: ICP research, positioning tests, competitor teardowns, outbound sequences, SEO-brief generation, experiment design.
You're not paying a growth operator for slow, manual consulting deliverables. You're paying for senior judgement applied to work that's already been accelerated by the tools, and a repeatable system your team can run after I've gone.

Essays on AI-native GTM, growth systems, and why most startup growth advice is wrong.

When growth gets noisy, build an operating system
The teams that scale well do not simply test more channels. They create a repeatable way to decide what to learn, what to measure, and what to do next.

Do customer research before you buy more traffic
When CAC rises, most teams respond by pushing harder on channels. The better move is usually to sharpen who the offer is for, where friction lives, and what language the market actually uses.

The right window for a fractional CMO
Fractional leadership works best when the company needs sharper decisions, stronger systems, and better cross-functional alignment before it needs another full-time executive layer.
