Spark GTM — Loic Jeanjean · GTM Advisor, Interim CMO, Investor

Strategy is cold.
Execution burns.

I help B2B SaaS founders turn early traction into predictable, compounding revenue — as an advisor in your corner, an operator in your org chart, or an investor on your cap table.

GTM Advisory Interim / Fractional CMO Angel Investing

One operator. Three levels of heat.

01 · Advisory

GTM Advisory

Ongoing strategic counsel for founders and marketing leaders, delivered through Hypergrowth Partners. I've been the person across the table from CEOs at companies like Descript — pressure-testing positioning, channel mix, and pipeline math before the board does.

Weekly or bi-weekly working sessions with your GTM leads
Positioning, ICP and messaging that sales actually uses
Pipeline modeling, channel prioritization, budget allocation
Hiring support: scorecards, interviews, offer calibration

02 · Operating

Interim CMO

Embedded 2–3 days a week inside your team, with full ownership of the marketing function. Built for companies between marketing leaders, ahead of a raise, or scaling faster than their org chart.

Own the number, the team, and the roadmap from week one
90-day diagnostic → rebuild → momentum plan
Option to convert to full-time when the fit is right

03 · Investing

Angel Investor

Small checks, big conviction. I invest in early-stage B2B SaaS, fintech and AI companies where distribution is the unfair advantage — and I work for my allocation.

/ 01

Diagnose & blueprint

A full-stack GTM audit in the first weeks: ICP clarity, funnel math, channel reality check. You leave with a 90-day growth map — not a 60-slide deck.

/ 02

Build & instrument

Channel priorities locked, outbound live, dashboards wired. The boring infrastructure that makes growth measurable instead of anecdotal.

/ 03

Execute & iterate

Campaign sprints, message testing, hiring pressure-tests. This is where pedal meets metal — and where most consultants disappear. I don't.

/ 04

Scale & hand over

A 12–18 month scale roadmap, an investor-ready growth story, and a team that runs the engine without me. Every playbook stays 100% yours.

Trusted by ambitious teams.

Loic is a brilliant, analytical and a highly strategic marketer adept at managing complex concepts and implementing high-impact, scalable solutions. Under his leadership, our organization enjoyed continuous growth.

Berk DikmenHead of Marketing Ops, Lucanet

I have strongly benefitted from Loic's extensive experience in structuring and managing a growing team. Building solid and transparent sales processes in just a matter of months.

Yann PetrettiMarketing Lead, Notion

They bring the kind of strategic firepower you'd expect from your cofounders. But they execute like elite operators.

Operator first. Everything else second.

I'm Loic Jeanjean — a GTM leader who's spent fifteen years building marketing engines inside some of Europe's fastest-growing companies, including Pleo and Ledger. Today I split my time between advising founders through Hypergrowth Partners, stepping in as interim CMO for scale-ups in transition, and backing early-stage teams as an angel.

Based in Lisbon. Operating across the EU, UK and US. Allergic to vanity metrics.
