Hey, I’m Tristan
I'm a fractional CMO for startups, based in Lisbon. I help founders work out which channels actually drive growth, then build the team and the process to scale them. Over the last 10 years that's been more than 100 startups across the UK, Europe and the US.

The community of growth experts
I co-founded Growth Division with Tom Dewhurst. For 7+ years we've built and run growth teams for top tier startups and scale-ups, pulling in the right specialists for each stage instead of one generalist hire.
The AI growth operating system
Expert-built growth systems, run for you and tied to your targets. Your tools and knowledge feed one GTM brain, and every activity, human or AI, traces back to your North Star Metric.
Want the longer version? Here's my story.
Three ways to work with me, depending on where your startup is and how much help you need.
01 · Fractional CMO
I've spent years inside startups in fractional growth roles: as a growth advisor at Startups.com, growth marketer and advisor at Breezy, fractional CMO at Squadra, and through Growth Division with teams like Oddbox, SeedLegals and LUX Rewards. I own the go-to-market strategy, the targets, the channel experiments and the team that delivers them.
How I work as a fractional CMO02 · Mentoring
I mentor founders and marketers at Unicorn Factory Lisboa, for Partech's portfolio startups and on GrowthMentor (where I'm sitting on 5.0 from 17 reviews, which still makes me smile!). Every week I keep 2 hours free for 30-minute sessions on GTM strategy, acquisition channels, building your growth team and using AI in your go-to-market.

03 · Speaking & workshops
I speak at events, turn up on podcasts, write guest articles and run go-to-market workshops for VC portfolios and accelerators. So far that's included Seedcamp, Partech, Shilling and Pre-Seed to Succeed. Fair warning: I could happily talk about growth all day!

Deepak Ravindran Founder & CEO A fractional CMO is a senior marketing and growth lead who works with your startup part time. In my case that means owning the go-to-market strategy, setting the growth targets, running channel experiments and building the team and systems that hit those targets, without you having to hire a full-time CMO before you're ready for one.
Usually once there's some traction but growth is still founder-led and hard to repeat. Other common moments: you've just raised and need a credible growth plan, a generalist marketing hire hasn't moved the numbers, or you're launching into a new market like the UK or US. If you're pre product-market fit, I'd honestly start with my free sessions instead.
An agency runs the channel you've already picked. A fractional CMO decides which channels deserve your money in the first place, sets the targets and is accountable for the overall number. I often end up choosing and managing the agencies, which is a very different job from being one.
Yes! I'm based in Lisbon but most of my work is with startups in the UK, across Europe and in the US. It's mostly remote, with in-person sessions where they add something.
In the UK most fractional CMOs charge somewhere between £3,000 and £12,000 a month, depending on how many days you need. I break it all down in my fractional CMO cost guide, and for early-stage startups I can work for cash, equity or a mix.
And that's me!
