Taiwan Semiconductor Manufacturing Company — the world's largest contract chip foundry, fabricating silicon for Apple, NVIDIA, AMD, and nearly every major fabless chip designer. Founded by Morris Chang in 1987, TSMC pioneered the pure-play foundry model and now sits at the center of global tech supply chains. Cited by Tobi Lütke as a craftsmanship exemplar: obsessive process discipline compounded over decades produces capability no one else can match.
