General Index (GX) delivers future-proof commodity prices. Our spot prices and forward curves are calculated algorithmically based on thousands of daily trades collated from 240+ data partners, using transparent and consistent methodologies and a compliant approach.

Producing 5,900+ daily prices in crude oil, refined products, natural gas and energy transition, we democratize access to benchmarks that represent real market activity. We’re easy to use, with hassle-free integrations and straight-forward licensing - providing more choice to the industry.

With offices in London, Krakow, Houston and Singapore, GX is now scaling our go-to-market team and we are looking for enthusiastic SDRs to join us, learning and growing alongside our business.

About the role:

We're looking for an experienced Sales Development Representative (SDR) to join our growing sales team. As an SDR, you'll be the first point of contact for potential customers, playing a critical role in driving General Index’s growth by identifying and qualifying new business opportunities.

  • Curious. You know that being a great salesperson requires a strong understanding of our data, technology and industry, as well as going above and beyond to know our customers’ and prospects’ challenges inside out.
  • Exceptionally proactive. If something is not entirely clear, you find a way by asking questions and experimenting.
  • Customer-centric. You care that our customers have a first-class experience with us and want them to thrive post-sale (not just during the sales process).
  • Ambitious and driven. You want to win and celebrate success with your team – ensuring we take GX to the next level.
  • Resilient. You understand that prospecting is tough and are able to handle objections and rejections along the way. Cold calling is a big part of the job, and you understand that it takes practice and persistence to succeed.
  • A team player. You enjoy collaborating with different departments in the business.
  • Commercially-savvy. You are comfortable working with numbers, working alongside our sales management to pull together complex proposals.

What you'll be doing:

  • Prospecting into target accounts via cold calls, emails, LinkedIn, and other outbound channels.
  • Qualifying inbound marketing leads and convert them into sales opportunities.
  • Researching prospects and identify key decision-makers.
  • Scheduling discovery meetings and product demos for Account Executives.
  • Maintaining accurate activity and pipeline data in CRM.
  • Following up consistently with prospects through multi-touch sequences.
  • Collaborating with marketing on campaigns and messaging feedback.
  • Meeting or exceed monthly quotas for meetings set and opportunities created.
  • Staying up to date on product offerings, industry trends, and competitors.
  • Developing a firm understanding of our data and markets – articulate how our data products solve problems and create opportunities for our customers.
  • Using AI tooling to enable and finesse our GTM processes.

About you:

  • Around 12 months’ experience in a similar Sales Development role.
  • Have an interest in Commodities markets and how these operate.
  • Have strong verbal and written communication skills.
  • Are coachable and eager to learn.
  • Familiarity with CRM tools (Salesforce, HubSpot, etc.)
  • Find working in office with your team exciting.

We offer:

  • Competitive salary and OTE.
  • Stock options.
  • Private medical insurance.
  • Covent Garden office.
