Juliette Devillard

Juliette Devillard is the Founder and CEO of Climate Connection, a skilled public speaking coach, and an author who specialises in climate technology and founder communication. She leads the UK's largest monthly gathering for climate professionals, having trained over 120 Seed to Series B founders in communication and fundraising after spending four years in the US working with early-stage deeptech and climate startups. Juliette collaborates with government, venture capital, and climate stakeholders to champion founders and drive investment into climate solutions. Her sessions equip audiences with practical strategies for building meaningful professional connections, strengthening their communication impact, and advocating for founder mental health and work-life balance within entrepreneurial ecosystems.

After launching Climate Connection in November 2021, Juliette Devillard transformed a single monthly gathering into the UK's largest climate professional network, now hosting more than 40 events annually that connect green startups, venture capitalists, corporates, and government representatives. Her vision for the platform emerged from four years spent working with early-stage deeptech and climate tech innovators in the United States, where she developed a sharp understanding of what founders need to scale climate solutions. Today, she collaborates with partners including the UK government, Google, and leading venture capital firms to champion entrepreneurs and accelerate investment into technologies addressing the climate crisis.

Juliette's credibility extends beyond event curation into the practical work of founder development. As a public speaking coach, she has trained more than 120 Seed to Series B founders in communication and fundraising, equipping them with the skills to articulate their vision and secure capital. Her writing for publications including Entrepreneur UK, Startups Magazine, and Tech Funding News explores themes of strategic networking, founder resilience, and what she terms 'quiet climate', a shift towards substance over signalling in the climate tech sector. This perspective, grounded in her direct experience supporting hundreds of founders, reflects her belief that efficiency and measurable impact will define the next phase of climate innovation. Her work bridges the gap between technical expertise and compelling communication, helping founders translate complex solutions into narratives that resonate with investors and customers alike.

Audiences working with Juliette gain actionable strategies for building meaningful professional connections, strengthening their communication impact, and navigating the unique pressures of climate entrepreneurship. She advocates passionately for founder mental health and work-life balance, working to embed resilience-centred programmes into startup accelerators and incubators across the ecosystem. Her sessions deliver practical frameworks that participants can apply immediately, whether they are refining their pitch, expanding their network, or creating sustainable working practices within high-growth environments. Juliette's approach combines the energy and ambition of American startup culture with a distinctly human focus on connection, purpose, and long-term wellbeing, leaving audiences better equipped to drive both commercial success and genuine climate impact.
