Jonas Helwig
Founder, CEO & Strategic Advisor

Jonas Helwig

I build software for electricity markets, and co-found companies in AI security and nuclear.

Twenty years in energy systems, still writing production code. Storage, trading and grid balancing on one side; AI security and the operational software an energy business actually runs on, on the other.

Who I Am

I am a founder and engineer. Co-founder of Kistora, which decides what an AI agent is allowed to do before it touches real systems, and co-founder of Nuclearis Energy. Over twenty-odd years the work has moved between energy markets, venture building and product, and it has never stopped involving code.

Day to day that means battery and sand-based thermal storage, energy trading, grid balancing, and AI built into the operational side of an energy business. I also write: essays on power and computation, and a novel about the Aum Shinrikyo case.

Focus Areas

What I Work On

Most of my time goes into energy systems and the software that runs them. The rest is split between AI security, nuclear, code I still write myself, and a book.

Battery & Thermal Storage

Grid-scale batteries and sand batteries, which store energy as heat in something cheap and abundant. Storage is what turns a volatile power market into a manageable one, and it is where a lot of the interesting engineering sits right now.

Energy Trading

Day-ahead, intraday and balancing markets. I work on the systems that price, hedge and settle electricity, where a few minutes of forecast error turns into real money in one direction or the other.

Grid Balancing & Robust Power Systems

Keeping supply and demand matched second by second as more of the grid becomes weather-dependent. Forecasting handles the uncertainty, storage and flexibility absorb the deviations, and firm capacity covers the long windless stretches.

AI Systems for CRM & Operations

Building AI into the daily machinery of an energy business: sales pipelines, customer records, billing questions, telephony, dispatch. Not demos, but systems people use every day and complain about when they are slow.

AI Security & Agent Governance

As co-founder of Kistora, I work on checking what an AI agent is about to do against policy before it acts, and keeping a signed record of the decision.

Nuclear Energy

Co-founder of Nuclearis Energy. Advanced nuclear, microreactors, and the unglamorous case for firm power: the electricity that is simply there when the wind is not.

Writing & a Novel

Essays on energy and AI, and a novel based on real events surrounding the Aum Shinrikyo cult, which started in the gap between the English account of the case and the Japanese one.

Projects

I maintain open-source and production systems alongside the company work. GOPBX is the public example: a telephony platform with a Go control plane and a SvelteKit frontend, with FreeSWITCH kept underneath where it belongs. MIT licensed.

FAQ

Frequently Asked Questions

Jonas Helwig is a founder, CEO, entrepreneur, and strategic advisor working across nuclear energy, artificial intelligence, commercialisation, industrial competitiveness, and long-term infrastructure.

He writes about nuclear energy, firm power, energy density, industrial policy, energy security, AI-related electricity demand, compute infrastructure, commercialisation, and founder execution.

He approaches AI as a systems question involving power, compute, product workflows and infrastructure, and builds AI into production energy tools rather than only writing about it.

The Nuclear Show is a podcast connected to Jonas Helwig and Adnan Belushi, focused on nuclear energy and related conversations with founders, operators, and policymakers.

Because nuclear provides firm, scalable, high-density electricity that supports reliability, industrial capacity, energy security, and long-term economic resilience.
