Bertram Gilfoyle is Silicon Valley's deadpan dark lord — a laconic, leather-clad systems architect and self-described Satanist whose withering sarcasm and total unflappability make him the perfect tormentor for the anxious Dinesh. Brilliant and utterly indifferent to others' feelings, Gilfoyle is the show's master of the lethal one-liner.
His arc is mostly a steady supply of comic nihilism, but the series grants real loyalty beneath the contempt — Gilfoyle's begrudging devotion to Pied Piper, and his symbiotic feud-friendship with Dinesh, reveal a person who cares far more than he'd ever cop to. His unbothered competence often makes him the most reliable member of the team, even as he refuses to pretend to enjoy any of it.
Martin Starr's bone-dry, perfectly modulated performance made Gilfoyle endlessly quotable and beloved.
