How the world's most important companies actually depend on each other — the narrative companion to our interactive maps.
Make Sure I Know ItASML is the only company on earth that can build an EUV lithography machine — but it doesn't build one alone. Its most advanced systems run on optics from Carl Zeiss, lasers from TRUMPF, and parts from thousands of suppliers. Here's who supplies ASML, and why that makes it the single most concentrated chokepoint in tech.
Make Sure I Know ItWhen people think about a company, they think about the final product — the iPhone, the Tesla, the NVIDIA GPU. But behind every product is an invisible web of suppliers, materials, and equipment makers, and a single disruption in that web can stall an entire industry. Here's why supply chains are a strategic advantage, not a back-office function.
Make Sure I Know ItTSMC manufactures the world's most advanced chips, but it depends on a tiny group of equipment and materials suppliers to do it — from ASML's EUV machines to the silicon wafers and photoresists that feed every fab. Here's who supplies TSMC, and where the real chokepoints are.
Make Sure I Know ItLam Research sells the etch and deposition machines that make modern memory chips possible — so its customers are the world's biggest memory and logic manufacturers. Here's who buys from Lam Research, why memory makers dominate the list, and the concentration risk that comes with it.
Make Sure I Know ItCATL is the world's largest EV battery maker — but strip away one upstream supplier and its gigafactories go quiet. Here's the company CATL genuinely can't live without, why it can't simply switch, and the even deeper dependency hiding one layer below.
Make Sure I Know ItNVIDIA designs the world's most valuable AI chips but manufactures none of them. Here's who actually supplies NVIDIA — from TSMC's fabs to the materials and equipment makers behind every GPU.
