These criteria ensure that Green Angel Syndicate backs scalable, impactful companies capable of delivering both environmental benefit and strong financial performance.
Assessment
Green Angel Syndicate follows a rigorous multi-stage assessment process designed to identify and support the most impactful climate innovations. The process begins with an online application, where each opportunity is screened for alignment with the syndicate’s mission to deliver measurable carbon reduction and support scalable, commercially viable technologies. The team evaluates the expertise of the founders, the maturity of the technology, typically looking for companies with a minimum viable product or at least Technology Readiness Level 5, and the strength of the business model, including market demand and competitive advantage.
After the initial filter, a member of the investment team engages directly with the company to gather further details and explain the investment process. Next, a group of Green Angel Syndicate’s specialist members, each with relevant sector expertise, reviews the opportunity to assess where the syndicate can add value to the company’s growth. If there is consensus, the company is invited to present to the full membership, but only a small percentage of applicants reach this stage.
If there is strong investor interest, the opportunity moves to a comprehensive due diligence phase that follows a venture capital standard. This includes technical validation, market fit analysis, intellectual property review, and an assessment of the company’s financial projections and exit strategy. The Investment Committee then reviews the proposal, particularly where there is potential for co-investment from the Climate Change Fund or the Regional Angels Programme.
Throughout the process, Green Angel Syndicate benchmarks each opportunity against global early-stage data and, when appropriate, consults external experts to validate both the technology and its potential for scale. This thorough approach ensures that every investment delivers measurable environmental benefits and real-world commercial value, with ongoing support from the syndicate’s extensive professional network.
