Growth Marketing Lead , London, United Kingdom

We’re looking for an AI‑first marketer who loves getting their hands dirty, thrives in fast‑moving environments, and can achieve outsized results with limited resources. You’ll work directly with our leadership team to shape our global marketing strategy, create compelling campaigns, launch new products, ensure commercial growth, and help further establish General Index as one of the most exciting companies in the commodities industry.

General Index (GX) is a commodity benchmark provider based on the most data. We produce over ~6,000 daily energy prices – in crude oil & refined products, biofuels, hydrogen, and carbon markets – which our clients (such as Exxon, Bloomberg, BP, Shell and Two Sigma) use to make critical energy & investment decisions. GX’s unique approach collates thousands of trades from 200 data partners and applies expert‑designed algorithms based on detailed methodologies to calculate prices. Backed at Series A by Chalfen Ventures and 20VC, we have an experienced team with proven leadership – as well as a rapidly growing customer and partner base. With offices in London, Krakow, Houston, and Singapore, we’re growing quickly, and we’re looking for a Growth Marketing Lead to help us tell our story, deepen our market presence, generate demand, and build a category‑defining brand.

About the Role

The right person will be relentlessly curious, commercially minded, customer obsessed, and excited by the possibilities that AI creates for modern marketing. You will:

• Own and execute the marketing strategy across brand, demand generation, content, events, partnerships and product marketing
• Build campaigns that generate awareness, engagement, pipeline and revenue
• Optimize our PLG motion in partnership with product and sales
• Develop a deep understanding of our customers, their challenges, and the markets they operate in
• Turn complex data content into engaging, accessible content in partnership with our product team
• Use AI tools to accelerate research, content creation, campaign execution and performance analysis
• Manage our website, social channels, email marketing and marketing technology stack
• Support major industry events, webinars and customer‑facing initiatives
• Create customer stories, case studies and thought leadership content (often working alongside key partners)
• Experiment constantly with new ideas, channels and approaches
• Track performance and continuously improve marketing effectiveness through data‑driven decision making

About You

Curiosity above all else. You don’t need to arrive as a commodities expert (although that would be a nice bonus). We’re far more interested in someone who is genuinely curious about customers, industries, technology and how markets work. You enjoy asking questions, learning quickly, and developing expertise in complex subjects.

AI‑first mindset. You are very active in using AI in your day‑to‑day work. You’re excited by how AI is reshaping marketing and are constantly looking for ways to work smarter and move faster in your pursuit of pipeline.

Strong marketing fundamentals. You’ve worked in environments where resources were limited and expectations were high. You know how to prioritize, execute and create impact without needing a large team around you. You understand how to:

• Build demand generation programs
• Create compelling content
• Position products effectively
• Support sales teams
• Measure marketing performance
• Manage multiple priorities simultaneously
• Use data to drive decisions on marketing investment
• Ensure brand consistency

Why Join General Index

• Help change an industry that is ripe for disruption
• Work directly with an experienced leadership team that genuinely values marketing
• Report to a CRO who previously built and led marketing teams herself
• Join a high‑growth, venture‑backed business at a pivotal stage of its journey
• Enjoy significant autonomy and the freedom to bring new ideas to life quickly
• Work alongside smart, ambitious people who care deeply about what they do
• Build a marketing function that can become a genuine competitive advantage

You’re someone who spots opportunities others miss. You read widely. You ask questions. You challenge assumptions. You enjoy figuring things out. You probably have a long list of ideas you’d love to test if only someone would let you.

You’ll receive:

• Competitive base salary.
• Private healthcare with BUPA.
• £2k annual L&D budget per employee.
• Pension scheme.
• Mentoring support
• Structured development, with a track record of internal promotions.
• Regular team socials, with a positive and high‑energy culture.

A diversity of identity, perspective, and experience makes us stronger. We welcome you to apply to GX regardless of your background, age, gender, ethnicity, orientation, or ability. Don’t meet all the requirements? At GX we believe that professional development happens through teaching and learning from your peers and managers. Even if you’re uncertain about whether you have the experience we’re looking for, please apply if this position sparks your curiosity and you have a real interest or passion in what we are doing.
