Cleantech Group

What Cleantech Group does

Cleantech Group is a private, Oakland-headquartered market intelligence and innovation advisory firm founded in 2002 that coined and trademarked the term "cleantech." The company operates the i3connect platform, a proprietary intelligence and networking system tracking over 40,000 startups and scale-ups and 21,000 investors globally, and supplements it with annual recognition programs (Global Cleantech 100, Cleantech 50 to Watch, APAC Cleantech 25, LATAM Cleantech 25), three annual Cleantech Forum conferences (North America, Europe, Asia), regional Spark events, and bespoke Innovation Advisory engagements.

The firm's core technology stack centers on i3connect, which delivers AI-enabled tools and dashboards for deal flow tracking, market segmentation, signal identification, value chain analysis, ecosystem benchmarking, and impact scoring. Underlying proprietary assets include the Impact Scoring Methodology, a credibility-and-scalability framework used to evaluate companies for recognition programs, and Value Chain Analysis tooling that decodes cleantech value chains from minerals to molecules to megawatts. The technology is differentiated by depth of domain specialization rather than novel AI architecture.

Cleantech Group monetizes through three primary streams: (1) annual membership subscriptions, with a free "Innovator's Plan" for startups and paid premium tiers tailored to corporations, investors, government, and foundations on a quote-based annual cadence; (2) event sponsorship and paid attendance at Cleantech Forum and Spark events; and (3) bespoke Innovation Advisory engagements including commercial due diligence and market landscape analyses. Go-to-market is direct-sales-led and event-driven, with advocacy coalitions (Cleantech for Europe, France, UK, Iberia, Italy) functioning as thought-leadership and policy-engagement channels funded in part by partners such as Breakthrough Energy and the European Climate Foundation.
