Principal Product Manager

Who We Are

We are rebuilding the energy transaction, making it transparent and fair. Our goal is to put power back where it belongs, in the hands of customers and to take on one of the most critical problems of our century, access to low cost electricity. tem exists to fix a broken global energy market that’s long favoured legacy operators, intermediaries, and opaque pricing.

Today’s electricity system was not designed for rapid decarbonisation, AI-driven efficiency or fair access for the actual users—businesses and generators. We’ve built the first AI‑native transaction infrastructure to reinvent how electricity is bought, sold and priced. Our technology is designed to cut out the inefficient fees, automate complex market flows, and bring transparency and fairness to energy transactions  late 2025, after extraordinary growth, we closed a $75 million Series B led by Lightspeed Venture Partners with participation from Atomico, Allianz, Hitachi Ventures, Schroders Capital and others—positioning us for global expansion, deeper product innovation and category leadership.

We’re scaling internationally and building toward a future where AI‑driven infrastructure is foundational to electricity markets worldwide. Since launch, our modern utility product, known as RED, has already facilitated thousands of business customers and billions in energy transaction value, proving that modern software and AI can transform an industry built on legacy systems. At tem, we’re not just building another energy company, we’re rearchitecting market infrastructure so that transparency, efficiency and sustainability become the default, not the exception.
