Sam Altman

Sam Altman is one of the great foundation-builders of the technology age, a man who shines not by chasing spectacle but by planting solid pillars and holding them steady. Born in St. Louis in 1985, he received his first Macintosh at eight, idolised Steve Jobs, and left Stanford after a year to co-found Loopt. From there he became president of Y Combinator, shepherding an ecosystem worth tens of billions (Airbnb, Stripe, Dropbox and more), before turning fully to OpenAI as its chief executive and, with ChatGPT, changing how the world talks to machines. His interests run to nuclear fusion, biometric identity and long-horizon bets.

His chart is a rare and potent stack: Sun, Moon and Ascendant all in Taurus, the earthy Venusian bull, all rising in the first house. The Sun in the first is the star born simply to be seen; the exalted Moon there, one of the healthiest lunar placements, gives steady instincts and a valuer's eye for quality. This is the archetype of the patient builder: immovable in his opinions, grounded, playing the long game while others rush. He is, in the truest sense, the pillar of his own solar system.
