GG Advisory helps climate-tech founders, energy transition leaders and sustainability-focused organisations turn complex ideas into fundable strategies, deliverable programmes and measurable outcomes.
Helping climate and energy technology ventures turn technical promise into credible commercial, investment and market-entry propositions.
Helping organisations assess energy-transition opportunities, build credible business cases and turn complex technology choices into executable investment and delivery decisions.
Helping organisations turn climate and sustainability expectations into practical priorities, decision-useful metrics and credible action.
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 major organisations and financial institutions, energy-transition assignments involving Shell and ARENA, emerging energy technology commercialisation, and hands-on venture commercialisation support helping technologies progress towards investment-ready outcomes.
Antonin collaborates with Pear Tree Labs on venture due diligence and investment access, mentors founders through EnergyLab and FACET HUB 4.0, and serves 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.
