Founded by industry insiders and backed by Visionaries Club and Yellow, Cepter builds the structured data layer, and the AI agents that work on top of it, that automate the manual, document-heavy work behind the development and transaction of energy infrastructure assets. The first application cuts investment and due diligence timelines from months to days: AI agents analyse thousands of commercial and legal terms in parallel, surface red flags and missing documents, and produce a full due diligence report in minutes, at a fraction of the usual legal costs. Where clients need legal reliance, established law firms review and sign off on the result. At launch, Cepter already supports transactions across more than 3 gigawatts of project capacity for developers and investors in Europe.
London, September 15, 2026 – Europe’s energy infrastructure buildout is attracting unprecedented levels of capital and development activity. Yet getting energy projects from investable to closed remains painfully slow. As electricity demand skyrockets due to AI, data centres, and industrial electrification, fragmented project data and outdated, costly legal review processes keep creating friction in the flow of capital into projects.
Cepter, the AI-native firm for energy projects, today launches to remove this bottleneck. Using Cepter radically accelerates the investment and due diligence process for solar, wind and battery storage assets for project developers, utilities, independent power producers (IPPs), energy investors and financing banks.
Unlocking the Full Potential of Europe’s Energy Infrastructure Buildout
"The energy build out doesn't have a capital problem. It has a friction problem," explains Kaspar Klemm, Co-Founder and CEO of Cepter. "The capital is there, the projects are there. But getting a deal from investable to closed can take months, most of it because of due diligence and legal review. While that clock runs, not a single megawatt gets built and the capital sits on the sidelines."
The underlying problem: the information needed to move capital into energy projects remains buried in unstructured documents. A single project carries hundreds to thousands of land leases, grid agreements, permits and construction contracts. Today that review is done manually - with investment teams spending months in data rooms alongside external advisors, and legal due diligence costs for a single asset routinely running into the high five to six figures.
The Solution: AI-Driven Speed Meets Legal Accountability
Cepter tackles this issue in three steps:
- Ingest & Structure: The Cepter Ontology, a purpose-built data model for energy infrastructure, transforms fragmented data rooms into a structured, machine-readable representation of an asset - capturing even the smallest detail, from land parcels and how they are secured to permits and their conditions, grid connections, offtake agreements, financing and corporate structure.
- Assess via AI Agents: Building on the Ontology, Cepter’s AI agents analyse thousands of commercial and legal terms in parallel, build a detailed project factbook, and run the documents against a lawyer-developed risk catalogue - surfacing red flags, missing documents and unmet conditions in minutes instead of weeks, each traceable to its source. Teams can then assign issues to an owner, resolve them, or send the full list back to the seller, while an AI assistant works like an extra analyst on the team.
- Sign off with Legal Reliance: Unlike pure software providers, Cepter integrates experienced in-house transaction lawyers directly into the workflow. Where legal reliance is requested, Cepter works together with established external law firms to review and verify the DD reports, giving clients a legally reliable deliverable in days rather than months, and at substantially lower cost.
Cepter supports both buy- and sell-side transactions, but its value extends beyond the transaction itself. It supports the entire lifecycle of an energy project: from early-stage development to commercial operation, and from asset management and M&A transactions to bank financing.
Built by People Who Have Lived the Problem
The team behind Cepter knows the problem first-hand. CEO Kaspar Klemm was employee number seven and Chief of Staff at terralayr, one of Europe’s largest battery storage developers and owner-operators, where he closed numerous co-development agreements and helped to raise over EUR 200 million in equity to finance its gigawatt-scale project pipeline. He co-founded Cepter alongside CTO Douglas Orsini-Rosenberg (ETH Zürich, IBM), with Dr. Maximilian Volmar joining as Founding Head of Legal. Previously at Linklaters and Freshfields, Dr. Volmar advised key players in the global energy sector, including BlackRock, Uniper, Nuveen, KfW, and Goldman Sachs, on a wide range of energy projects from solar and battery storage to onshore and offshore wind.
Live in the German Market, with an Ambitious Roadmap
At launch, Cepter is already being used by numerous European project developers, IPPs and infrastructure investors in the German market, and plans to expand across Europe and the US, with the ambition that every energy infrastructure asset is represented in Cepter across its entire lifecycle - from first development document to decommissioning.
