We're excited to announce the Sustainable Startup Investment Summit. On October 1st, 2025, investors are invited to join us at Plaisterers Hall in London for exclusive pitches from Britain’s most promising sustainable startups.
Following the success of our EIS Investment Forum in April, which brought together 300 members of our investor community for an evening of invaluable insights and connections, this October's summit is set to be our biggest event yet.
Why Attend?
More than a networking gathering, this summit provides a critical bridge between capital and innovation. This is strictly an investor-only event, ensuring a focused environment for investment opportunities. The evening will feature a curated lineup of sustainable founders who will pitch their ideas and then you will be given the opportunity to ask your own questions. The ventures range from early-stage ventures to those further along in their fundraising journey. Some of the startups presenting will be EIS registered, offering attractive tax reliefs for eligible investors.
The event provides a unique opportunity to fully immerse yourself in the sustainable investment landscape. Surrounded by like-minded investors, you'll have the chance to engage in meaningful discussions about your own portfolio and gain insights into where the market is headed. We bring a community of high-net-worth individuals, sophisticated investors, and family offices, ensuring a rich environment for connection and growth. Moreover, our sponsors, who will shortly be announced, will be in attendance, offering further opportunities for networking and collaboration.
The Time for Sustainable Investment is Now
"The EIS Investment Forum was a game-changer for Roarsome," says Will Chapman co-founder of Roarsome, a startup that pitched at our previous event.
"The exposure to a targeted investor community was invaluable, and it contributed to securing the funding we needed to scale our impact. We highly recommend this platform to any sustainable startup."
Daisy Moll, our Editorial Manager, emphasises the importance of this event: "The shift toward sustainable investment is already underway, with economies investing trillions to address environmental challenges. Investors are seeking climate-aligned opportunities, and startups are responding with innovative, high-impact solutions. This summit is where visionaries and change makers converge, connecting capital with innovation to accelerate a more sustainable and equitable future.”
Carnot Engines said, "The EIS Forums are unique in their ability to attract a wide variety of highly engaged, relevant and interesting people from across the sustainability landscape. Carnot were lucky enough to be invited to present and all three of us spent the whole evening rushed off our feet with interest from investors. Wonderfully organised events, brilliant team and thoroughly enjoyable."
