Devrim Celal– Kraken

In this episode of Leaders in Cleantech, David Hunt is joined once again by Devrim Celal, Chief Flexibility & Marketing Officer at Kraken, nearly six years after their first conversation in 2019—back when Devrim was CEO of Upside Energy.

Since then, Upside Energy was acquired by Octopus Energy and evolved into Kraken, now one of the world’s leading energy technology platforms, serving tens of millions of customers and optimising flexible power at global scale.

Rather than a linear success story, Devrim reflects on the last decade as a series of distinct phases: early uncertainty, pivotal strategic pivots, the acquisition decision, rapid scaling within Octopus, and now Kraken’s transition into a fully independent global company.

The conversation explores leadership at scale, the reality of building culture through growth, the trade-offs founders face between conviction and adaptability, and what the future holds for flexibility, storage, EVs, data centres and grid optimisation.

This is a thoughtful, honest discussion about long-term impact, not short-term hype—and what it really takes to build enduring companies in the energy transition. 

Devrim Celal:
Devrim is the Chief Flexibility and Marketing Officer at Kraken. Overseeing Kraken’s flexibility and product capabilities, the cloud-based flexibility platform controls and optimizes distributed energy resources such as batteries of all sizes, EVs, solar and wind generation or heat pumps with machine learning and AI to match electricity supply and demand, helping the electricity grid deal with the natural volatility of renewable generation. Kraken is currently contracted to manage over 42 GW of power.

Previously, Devrim was the CEO of Upside Energy, which was acquired by Kraken in 2020. Before starting Upside Energy, Devrim’s professional career saw him take up executive roles with blue chip management consultancies and finance companies such as Publicis Sapient, Kearney and Lansdowne. He also holds an MBA from Yale University. In 2023, Devrim joined the Elexon Board, which manages the Balancing and Settlement Code of Great Britain’s energy system, as a Non-Executive Director.

In this episode of Leaders in Cleantech, I speak with Juergen Mayerhofer, CEO and co-founder of enspired, the Vienna-based company using fully automated, AI-driven trading to optimise flexible power assets – especially grid-scale batteries – across multiple European markets.

Juergen shares how he stumbled into energy via Austrian gas market liberalisation, fell in love with physical energy systems, and eventually founded enspired in early 2020 with the simple but powerful idea that flexibility is the key resource for integrating more renewables. We talk about how the company has scaled from its first pump storage and thermal assets in Germany to managing ~5 GW of flexibility (including over 1.3 GW of batteries), now active across ten markets and expanding into new geographies.

We dig into why enspired thinks like a software and R&D company rather than a classic trading house, how they use automation, machine learning and reinforcement learning in practice, and why they’ve chosen to publish independently verified revenue performance instead of leaning on AI buzzwords. Juergen also reflects on the realities of founding just before COVID, expanding rapidly across borders, and building a diverse, high-performance culture designed to move into new countries in weeks, not years.

About Juergen Mayerhofer:

enspired CEO and co-founder Juergen Mayerhofer holds an MBA in energy management and has worked in the energy sector for over 20 years, contributing to the expansion of renewables in the grid in various expert positions. Under his bold and devoted leadership, enspired evolved from a small-scale startup with a workforce in the single digits into a successful institution with global recognition. As an enthusiast and first mover in BESS optimization, Juergen is a highly respected and trusted figure in his field as well as the power industry at large.

In this episode I’m joined by Gregory Dewerpe, Founder of NOA  (formerly A/O), to cut through the noise on climate investing. We talk about the shift from abundance to discipline, why Europe and the US are now playing different games, and how AI will matter in the physical world—grids, buildings, materials—rather than the hype layer. Candid, practical, and economics-first: adoption wins when solutions are cheaper, smarter, and scale.

What we cover

• Why A/O became NOA: moving from “proptech” to a broader physical world mandate; why naming and focus matter for specialist funds; being memorable and thesis-true.
• Specialist > generalist: generating alpha by doing the less obvious in crowded markets; why NOA prefers hard tech and infrastructure over “consensus safe” deals.
• How NOA deploys: flexible first cheques ($2–15m), stage-agnostic from seed to B; focusing on capital actually at work by Series B rather than chasing ownership optics.

Some of Greg’s quotes 

• “We won’t generate alpha by doing what everyone else does. Being a specialist lets us have a qualified, differentiated opinion.”
• “The built world doesn’t need to be greener — it needs to be smarter. Make it smarter and it will be greener.”
• “We shouldn’t build climate on altruism. Adoption happens when solutions are cheaper and more efficient.”

About Gregory Dewerpe

Gregory Dewerpe is the Founder and Managing Partner of noa, Europe’s largest built world venture capital firm. He oversees the firm’s vision and strategy, manages partnerships with portfolio companies and LPs, and is a recognised voice in tech and climate—particularly around decarbonisation and the energy transition in real estate.

He founded noa (formerly A/O) after more than a decade of deep investment in the real estate sector, identifying it as a key vector for climate innovation. This insight stemmed from his previous work founding AMD Capital, a specialist real estate investment and advisory firm.

Earlier in his career, Gregory worked in investment banking at Credit Suisse and Citigroup, where he structured over $30bn in new investments. He holds an MSc in Business & Finance from HEC Lausanne and has attended executive education programmes at LSE and Harvard Business School.
