Customer Success Manager, Enterprise

About Electric Twin Most organisations make their biggest decisions on a thin slice of evidence — a handful of customer calls, one survey, instinct when the data runs out. Electric Twin changes that. We're a behavioural simulation platform that lets organisations test ideas, messages, and decisions against synthetic populations — digital twins of real audiences — and get answers in minutes that would otherwise take weeks. The work is grounded, and the engineering is real. We've run over 40,000 evaluations across populations covering 155 countries. Independent academic research with Professor Michael Muthukrishna at the LSE found our outputs come back roughly 10,000× faster than traditional methods, at 95% accuracy. AI is part of what we build, but it isn't the product. The hard work is system design, data, orchestration, and making outputs trustworthy enough that people act on them. Running population-scale simulations is a systems problem as much as a science one — foundation models, behavioural data, evaluation pipelines, and the infrastructure that holds them together, with real engineering problems at every layer. How the work gets done here isn't handed down — it's worked out by the people closest to it. You'd help shape what gets built or sold and why, decide where the trade-offs sit between speed and depth, and judge when something is ready for customers and when it needs another pass. What the role involves day-to-day, what your first six months look like, and how compensation, equity, growth and flexible working are structured are all set out in detail below — the headline is that early joiners get meaningful equity, a clear path to grow with the company, and the flexibility to work around the rest of your life. Electric Twin was founded by Dr Ben Warner (former Chief Data Advisor to the UK Prime Minister) and our CEO, Alex Cooper (a former senior military commander and Director of Mass Covid Testing in the pandemic). We're backed by top tier investors including Atomico, LocalGlobe, Mercuri, and angels including Marc Andreessen. We have a high-class team of engineers, AI researchers, behavioural scientists, and operators — careful with the science, careful with the responsibility. The Role We're looking for a Founding Customer Success Manager, ideally with a strong quantitative research background, to join our team. This is a relationship-first role, focused on helping clientside insights teams and their internal stakeholders to get confident and self-sufficient on our synthetic audiences platform. This person would seek to build the trust that turns early usage into deep, organisation-wide adoption. Our platform is self-serve, but getting clients to that point takes genuine expertise and attention. Insights teams are typically our entry point and internal champions, but the real opportunity is broader. Our ambition is that the Electric Twin platform is directly used by commercial, product, and marketing teams in addition to the insights function. You'll help make that happen: guiding early users to value quickly, then working with insights leads to expand the platform's footprint across the business, including multiple markets. This is as much a building role as it is a doing role. You'll be defining how CS operates at Electric Twin - the playbooks, the health frameworks, the onboarding programmes - while owning client relationships from day one.
