GG Advisory helps climate-tech founders, energy transition leaders and sustainability-focused organisations turn complex ideas into fundable strategies, deliverable programmes and measurable outcomes.
We work hands-on with climate-tech and agri-tech founders to build the commercial foundations required to reach fundable, market-ready outcomes.
We help organisations turn energy transition strategy into funded programmes, operational change and measurable financial value, drawing on direct project experience with Shell, ARENA and Powerlink.
We help organisations make sense of ESG and sustainability expectations, turning complexity into clearer priorities, credible climate-related narratives and practical next steps.
GG Advisory was founded by Dr Antonin Demazy de Fortet, a climate-tech and energy transition adviser with a PhD in AI-enabled energy systems modelling from the University of Melbourne and an Executive MBA from ESCP Business School, one of Europe’s leading business schools.
With more than two decades of experience across Australia, Europe and Asia, Antonin brings a rare combination of technical, commercial and delivery perspectives. His work spans large-scale transformation programmes for Fortune 500 companies and major financial institutions, energy strategy projects for Shell, ARENA and Powerlink, and hands-on venture commercialisation support for climate and agri-tech start-ups progressing towards investment-ready outcomes.
Antonin collaborates with Pear Tree Labs on venture due diligence and investment access, mentors founders through NAFI and EnergyLab, and sits on the board of La French Tech Australia. This gives GG Advisory a strong Franco-Australian perspective and a practical understanding of how to connect innovation, capital, policy and execution across markets.
In 2026, Antonin was recognised as the winner of the Belgian-Australian Excellence Award in the Environment and Sustainability category.
At GG Advisory, integrity, dedication and empathy guide how we work. We operate alongside clients rather than above them, combining strategic insight with hands-on delivery to turn complex energy transition, ESG and climate-tech challenges into practical, fundable and executable outcomes.
