Data Centres already emit more carbon than the entire aviation industry, and with AI fuelling a new boom in data centre construction, they will consume almost 10% of global electricity by 2030. heata believes this to be incompatible with a Net Zero future. Backed by British Gas, heata has reimagined the data centre as a network of distributed servers inside people’s homes, where they capture the waste heat from data processing and use it to provide people who need it with free hot water. heata reduces energy use by 80% and helps people in fuel poverty at the same time. With a network of heata units installed in homes throughout the UK, companies are already joining the heata network to reduce the carbon footprint of their IT whilst giving back to their communities.

IONA is developing hyper-efficient autonomous delivery networks combining drones and robotics for shipping companies losing hundreds of millions every year with last-mile, due to empty cargo bays, scattered delivery points, and driver shortages. We fight isolation - especially in rural communities - and mitigate 200Mt+ of CO2e emissions by avoiding the use of inefficient 3T trucks when they are running empty. We leverage a new regulatory framework and components off-the-shelf to provide a turnkey hardware-as-a-service solution that turns last-mile into the most profitable and well-serviced segment for logistics companies, with secondary markets in industrial and medical deliveries.

Odin lets anyone, anywhere launch and run a private investment firm online - think Shopify for Venture Capital and Private Equity. We handle the full back office stack end to end, flexibly: legal structuring, investor onboarding, KYC/AML, payments, tax, reporting, and exits. We administer over $500m in assets, covering investments from pre-seed to pre-IPO. This includes household names like OpenAI and SpaceX but also new companies focusing on tons of cool things like: - Next-gen micronuclear reactors - Atmospheric CO₂ removal at gigaton scale - Asteroid mining - Space-based manufacturing (fiber, alloys, pharmaceuticals) - Crazy biotech eg. wet computers based on human neurons We believe capital is one of the most powerful tools for shaping the world - and more people should be putting it to work. We also have a strong conviction that some of the best capital allocators do not fit the “traditional mould” of a VC or private equity investor. If youve got sector expertise in an interesting field, youve never been an VC / PE investor before but youve thought about it, feel free to reach out.
