Head of Growth Marketing

We Are Sparta
Sparta is the next-generation commodity trading platform.
We give trading desks the clarity, control, and collaboration they need to move faster and trade smarter.
In February 2025, we secured $42 million in Series B funding. Now we’re scaling up across the business, and it’s an exciting time to join.

Our people are the driving force behind everything we do. At Sparta, you’ll be trusted to take ownership, backed by a team who wants you to succeed. You’ll be challenged, supported, and given room to grow. Because building something this ambitious takes everyone at their best.

At Sparta, your work has reach. From improving our platform, to powering smarter decisions for our customers, to changing how commodity trading is done around the world.

And because we’re growing fast, you won’t just build your career. You’ll accelerate it, with a level of ownership and impact you simply don’t get at bigger, more bureaucratic companies.

Sparta has the raw material most companies never get: a well-defined ICP with an engaged audience of traders, a genuine PR and analyst engine, product usage telemetry, and a stack rich with intent data. What we don't have yet is all of it connected into one demand engine that turns every signal into pipeline and revenue.

That's your remit. You'll build and run Sparta's demand engine end to end, from the first buying signal to closed revenue, on a single unified pipeline in HubSpot. This is a hands-on, high-ownership role: you'll design the architecture and set the strategy from day one, then build and lead the team around it as it proves out.

This role reports to the Chief Marketing Officer and can be based in either London or Geneva.

• Scale the demand-creation engine that's already working (analyst commentary, PR, webinars, the Market Outlook) and build a website and programs that turn our community into signal.

• Build the process to catch in-market demand the moment it appears, running paid, retargeting, SEO/AEO and lifecycle programmes.

• Own the signal-based pipeline architecture, unifying first-, second- and third-party signals into one HubSpot record.

• Fix and own the martech stack (HubSpot, Clay, ZoomInfo, Lemlist, event tooling) and cut what overlaps.

• Replace vanity metrics with honest reporting: real conversion rates, real source of pipeline, numbers the business can actually plan against.

• Build the marketing-to-sales handover that works: shared lead definitions, SLAs, and an account-based motion inside our existing accounts.

• A track record building and running a demand engine in B2B SaaS: you've owned pipeline and revenue, not just leads and MQLs.

• Hands-on experience with HubSpot, intent platforms and preferably also Clay: workflows, lead scoring, lifecycle stages, attribution and reporting. You can build automation, not just brief it.

• Strong collaborator with Rev Ops, as we build one clean, signal-based pipeline.

• Fluency with intent and signal-based marketing, and the discipline to make signals drive action.

• Comfortable being the person who says the real number out loud, even when it's not the one on the dashboard.

• The judgement to set strategy with the CMO, prioritise ruthlessly, and hire and grow a team as the function scales.

Nice to have: experience with account-based marketing for expansion inside existing accounts; a background in commodities, trading, fintech or data/analytics products; content-led or community “dark social” demand-creation experience.
