What Z/Yen does

Z/Yen (Z/Yen Group Limited) is a City of London-based commercial think-tank, consultancy, and venture-style firm founded in 1994 by Michael Mainelli and Ian Harris. The firm describes itself as a risk/reward management and research organisation whose core output is a portfolio of recurring proprietary indices — the Global Financial Centres Index (GFCI), China Construction Bank Global Green Finance Index (GGFI), and Smart Centres Index (SCI) — which benchmark 92-120 financial and commercial centres globally on a bi-annual or annual cadence. Adjacent operations include the FS Club (a networking community running ~200 events per year for executives across business, technology, and finance), SpecialiZm (an expert resourcing division placing senior managers on 6-18 month assignments), the Long Finance research programme, the ExtZy prediction-market community, and the ESOP Centre (a non-profit promoting broad-based employee share ownership, founded 1987).

Z/Yen's revenue model blends professional services with recurring sponsorship and membership streams. Income is generated from client consulting projects across financial services, technology, civil society, and commercial sectors; FS Club membership and event registrations (processed via Worldpay); recurring index sponsorships (notably China Construction Bank for GGFI, alongside the China Development Institute for the Chinese edition of GFCI); book sales (e.g., Clean Business Cuisine at £14.99 retail with bulk pricing from £7.50 per copy for 100+ units via Amazon and direct); and SpecialiZm placement fees for interim management experts. Pricing on consulting, sponsorship, and FS Club membership is quote-based and not publicly disclosed.

The firm operates from a single registered office at 1 King William Street, London EC4N 7AF, with a permanent staff estimated at 1-10 employees. Z/Yen has no disclosed external investors, parent company, or institutional ownership; control rests with the two founder-directors, and the company has organically built its affiliated initiatives rather than grown via M&A or venture funding. It has produced books including Clean Business Cuisine (2000) and The Price of Fish (2011), and continues to publish index editions and host events through 2026.
