What TDi Sustainability does

TDi Sustainability is a UK-based, founder-owned advisory firm that combines deep managerial and technical consulting with a proprietary SaaS platform to manage ESG and supply-chain due-diligence risk in metals and minerals value chains. The firm's services span strategy development, supply chain risk mapping, due diligence, human rights and FPIC advisory, supplier engagement, audit preparation, sustainability reporting, and training, delivered across Mining, Electronics/Automotive, Jewellery/Luxury, Finance, Government, and Standards-setter clients including Anglo American, Rio Tinto, Vale, Newmont, Glencore, Bulgari, Cartier, LVMH, Dyson, Amazon, the Asian Development Bank, ICMM, and the World Economic Forum.

The TDi Digital Platform is the productised layer of the business — a cloud-based, subscription-access supply-chain risk management system with five integrated modules: the Commodity Risk Tool, the Country Risk Tool, the Search360° News Monitor for supply-chain risk monitoring, the Enhanced Due Diligence Tool (TEDD), and the Standards and Regulations Tool (ICAT). These modules aggregate supplier, country, regulatory, and news-flow data to support transparency, ESG risk identification, and due-diligence compliance workflows (e.g., EUDR, conflict minerals).

Commercially, TDi combines three revenue streams: an annual subscription to the Digital Platform (quote-based pricing post-demo, one-year terms with 60-day renewal notice), professional consulting services (engagement-based, likely multi-year), and training/capacity-building programmes. The firm operates an enterprise field-sales GTM targeting Fortune 100 companies, governments and major associations, supplemented by an event-driven thought-leadership motion (podcast series Suits & Boots, webinars, Mining Indaba participation), and convenes five industry-leadership initiatives (CiPPPA, NPG, SSI, CGWG, LB360°) that confer ecosystem influence disproportionate to its sub-50 headcount.
