About this grant
Twynam Earth Fund II is a deep technology venture capital fund that invests in breakthrough technologies with large-scale CO₂ impact through first-principles engineering. The fund operates with a global mandate across key industrial sectors including food production, oceans, carbon capture, energy, built environment, mining and industrial processes, logistics and mobility, and waste. Twynam believes that decarbonisation will be driven by cleaner technologies that are cheaper to own and operate than incumbent solutions, focusing on dominant economics and profitability as the ultimate sustainability metric. The fund invests from pre-seed to Series B stage with cheque sizes of US$100,000 to US$3,000,000, and deploys capital flexibly based on company stage and needs. Fund I (2023 vintage) is tracking top-quartile performance to date as of January 2026.

Relevant sectors
About this sector
Industrial decarbonisation funding helps heavy industry cut emissions through electrification, fuel switching, process change and efficiency. Support is often capital-intensive and tied to a specific site, with feasibility studies leading to larger deployment calls. Applicants need emissions baselines, engineering studies and a plan to keep production running during the change.
