The energy transition doesn't have a capital problem. It has a friction problem. The capital is there and the projects are there, but getting a project from investable to closed still takes months, most of it spent reading documents.
cepter is the AI-native firm for energy infrastructure.
Every (renewable) energy project runs on documents. Leases, permits, grid agreements, EPC contracts - hundreds or thousands per asset, none of it structured. So the answers people need sit on page 24 of a PDF nobody has opened since signing, and every party in a transaction rebuilds the same picture from scratch, by hand, every time. That costs months on every deal and five to six figures per asset in external legal fees.
How it works
You upload the data room, and AI agents populate the Cepter Ontology - a purpose-built data model of what a renewable energy asset actually consists of. Land and how it's secured, permits and their conditions, grid connection, offtake, financing. From there you get a complete project fact sheet in minutes, answers to any question about the data room traceable to the source paragraph, and a full legal due diligence report against a catalogue of hundreds of lawyer-developed checks - including the documents that are missing entirely.
We don't just sell software
We deliver the work. Our own lawyers review the output before anything is final, and through an independent regulated law firm entity we provide full legal reliance on the report.
Purpose-built AI plus real legal accountability.
Where this goes
Legal due diligence is the wedge, not the ceiling. From there: more diligence types, more markets, and the wider workflow of energy infrastructure companies - development, financing, contract management, asset management. The same documents, the same bottleneck, the same solution.
Every energy asset in Europe should pass through cepter. Today they pass through inboxes and shared drives.
Where we are
Already live with leading power producers, developers and infrastructure investors in the German market. Backed by Visionaries Club, Yellow, and angel investors including the founder of n8n, the founders of terralayr, and a former Director of Product at Google DeepMind.
Kaspar (CEO) studied Philosophy, Politics and Economics at Oxford and started his career as a strategy consultant at BCG. He quickly realised that building slides for blue-chip corporates was not what he wanted to do long term. He had known since university that he wanted to build something himself, and the closest thing to training for that is working inside a startup. He joined a pre-seed company as employee #1, built the MVP and led the go-to-market. For the last two years before starting Cepter, Kaspar was Chief of Staff at terralayr, an tech-enabled battery storage developer, investor and and operator company backed by Creandum, Earlybird and others, where he led partnership deals over several GWs and more than €250m in capital raises, and helped grow the company to 60 FTEs and multi-million revenue.
Douglas (CTO) studied Computer Science at ETH Zürich, where he took his Bachelor's and went on to graduate study focused on artificial intelligence. At LGT Capital Partners he built the VC team's data infrastructure end to end, automated data ingestion across diverse sources, and launched live BI dashboards that gave investors real-time visibility into portfolio performance and market trends. Most recently he was an AI Engineer at IBM, designing and deploying production-grade AI microservices and APIs: modular, fault-tolerant systems with full CI/CD, spanning retrieval-augmented generation to large-scale data processing. He previously co-founded Trace, a personal finance AI, in ETH's Talent Kick incubator.
**Max (Founding Head of Legal)** is a fully qualified lawyer who spent his career in the energy and infrastructure practices of two Magic Circle firms, Linklaters and Freshfields, advising on some of the largest energy and infrastructure mandates in the German market. These are transactions where a single missed condition in a grid connection agreement moves nine figures. That is exactly the work Cepter is automating, and Max knows better than anyone which parts of it an AI can be trusted with. He joined to build the legal side of the company: his topics include the check playbooks our agents run against, and the review process behind every report.
