Founded in 2009 by strategy consulting professionals with a passion for energy and innovation, E-CUBE Strategy Consultants was created with a clear conviction: the profound changes underway in the energy and environmental sectors require strong industry expertise to address the strategic challenges of our clients. From the outset, commitment and creativity have been at the heart of our DNA. Over fifteen years, we have grown into a firm of 40+ consultants operating from four offices across Europe — Paris, Lausanne, London, and Brussels — delivering more than 150 projects each year for over 300 clients ranging from mid-sized companies and large corporations to investment funds and public authorities. Today, E-CUBE continues to grow, guided by a passionate and committed team determined to help clients move towards sustainable and resilient business models.

We are a team of consultants united by a shared purpose: to actively contribute to the energy and environmental transition through the work we do every day. Engineers, strategists, economists, and data specialists, we bring together top-tier skills across energy, transport, and decarbonisation — not as generalists, but as genuine sector experts who have worked exclusively in these fields since the firm's inception. Our founding partners built E-CUBE after careers in Anglo-Saxon consultancies, and they instilled in us a practice that dives deep into complexity and analytics while always returning to a human scale to support managerial decision-making. From interns to partners, every member of the team can count on the engagement of everyone else — and 100% of our employees feel they can trust in the quality of our collective work.

E-CUBE works with private and public economic players across three of the major challenges of the 21st century: energy and infrastructure, transport and mobility, and climate strategy and decarbonisation. Our interventions range from market analysis and development strategy to Strategic and Commercial Due Diligence for investors and companies seeking financing — covering assets from LNG terminals and renewable electricity production to electrochemical storage, energy efficiency, and electromobility infrastructure. We support organisational transformation and performance improvement when sectors are reshaped by liberalisation or the energy transition, and we design bespoke data models and analytics solutions to address the growing complexity of energy and transport markets. We also develop proprietary analytical tools — including our Biomethane Analytics platform and Linaria, our Electricity Network Analytics tool — that translate data into strategic and operational decisions. Whatever the intervention, our added value lies in the same place: sector expertise that is deep enough to anticipate where markets are heading, and a pragmatic approach that keeps client outcomes firmly at the centre.

E-CUBE was founded on the conviction that the energy and environmental transition is not a constraint to manage but an opportunity to seize — for businesses, for institutions, and for society. We exist to help companies and organisations navigate the strategic complexity of that transition: to turn decarbonisation ambitions into credible action plans, to identify the business models that will remain competitive in a low-carbon economy, and to ensure that the profound changes transforming energy, transport, and industry generate real value rather than mere compliance. The energy and environmental transition is our intellectual playground. It is what draws us to this work, what sustains our commitment to our clients, and what gives meaning to every project we take on. As we wrote at the dawn of 2025: we bear collective responsibility to make these transitions into more than addressing environmental constraints — they are opportunities to create value, growth, and employment for our societies.

Commitment to the energy and environmental transition is the foundation of who we are. We recruit consultants who are genuinely passionate about decarbonisation and who approach that commitment with both humility and determination. Customer engagement is the primary objective of every mission: we mobilise our sector expertise, our proximity, our responsiveness, and our flexibility to ensure the success of each client and build lasting trust. The initiative spirit means that our teams have the freedom and the support to propose and implement projects aligned with their passions — it is how we continue to grow beyond our historical boundaries, and how our first employee became our first additional partner. Excellence is not a corporate slogan but a guarantee: the quality of our expertise and know-how is the promise we make in every project we are entrusted with. Finally, balance is a firm belief. An engaged, high-performing consultant also needs to live a fulfilling life, and every manager at E-CUBE is responsible for ensuring that the boundary between professional and personal life is respected.

E-CUBE's promise is simple: only a team that works continuously in the energy, transport, and decarbonisation sectors — monitoring their regulatory, technological, and market evolution day after day — can truly support companies in anticipating change, navigating shifting public policies, and identifying winning business models. Our expertise covers more than 50 country-level energy and climate scenarios, all modes of transport, and the full value chain of energy systems from production and storage to networks and end use. We combine that depth with a resolutely pragmatic approach: our analyses are grounded in robust techno-economic models, our recommendations are built for managerial decision-making, and our support is sized and shaped to the specific context of each client. Proximity, responsiveness, and flexibility are not commitments we make at the start of a project and forget — they are the daily standard by which we measure client success. From the first case study to the final board presentation, we are with our clients all the way.

At E-CUBE, sustainability is not only the subject of our work — it is embedded in how we operate as a firm. We pursue CSR certifications including EcoVadis and B-Corp, applying the same rigour to our own environmental and social performance that we bring to our clients' decarbonisation strategies. We actively favour soft mobility and rail travel as part of our commitment to environmentally friendly practices, and we offer our Paris-based consultants a company bike programme to support low-carbon commuting. The transition we advise on every day is one we are working through ourselves, aligning our operations and culture with the convictions that led us to build this firm in the first place.

Commitment at E-CUBE extends well beyond client engagements. Our teams are involved in associative initiatives, share knowledge with students in partner schools, and participate in the broader intellectual conversation around the energy and environmental transition through published research, point-of-view papers, and sector outlook work. We believe that contributing to a more sustainable world requires action at every level — from the boardroom strategies we help shape to the communities and institutions we engage with directly. The E-CUBE weekend, regular team events, sporting challenges from the 20km de Paris to mountain hikes, and a culture of genuine collective spirit mean that our sense of community is something we actively build, inside the firm and out.

At E-CUBE, we believe that the best solutions emerge from collective efforts, and that a collective effort is only as strong as the conditions it creates for every individual within it. We are committed to fair remuneration with transparent salary projections, individual and team bonuses, and flexible working arrangements that respect each consultant's personal constraints. Continuous training is built into every project — from project managers to partners — supplemented by internal knowledge-sharing sessions and external organisations. Over 80% of our employees are satisfied with their responsibilities and opportunities for growth, and we take that figure seriously as both a measure and a commitment. Whether you are a junior consultant on your first assignment or a partner shaping the firm's strategic direction, E-CUBE is a place where what you do elevates you professionally and intellectually — and where you are supported to build a career that is genuinely yours.
