ZUCKERBERG BOUGHT INTO SCALE — THEN HIRED THE FOUNDER
Meta's 2025 investment put a roughly $29 billion value on Scale and moved Wang from supplying the AI race to running one of its biggest contestants: Meta's superintelligence effort.

19, MIT DROPOUT, SOLD META 49% OF SCALE FOR $14.3 BILLION
Wang left MIT at 19 and built Scale AI around the industry's least glamorous bottleneck: humans labeling data so models know what good looks like. Scale became infrastructure for cars, frontier models, and the Pentagon — then Meta paid $14.3 billion for 49% and recruited Wang to run its superintelligence effort.

BORN IN LOS ALAMOS TO TWO PHYSICISTS
Wang grew up in Los Alamos, New Mexico, where both of his parents worked as physicists at Los Alamos National Laboratory. He later described a childhood steeped in math, science and the lab town's unusually technical culture.

19. MIT DROPOUT. THE BORING BOTTLENECK.
Wang left MIT and founded Scale AI around a simple constraint on machine learning: models were getting better, but the raw data they needed still had to be cleaned, labeled and turned into usable training material.

HUMANS DRAW BOXES. THE CARS LEARN TO SEE.
Scale's early product turned human annotation into an API. Self-driving teams sent in road images; Scale's workers labeled cars, pedestrians, signs and traffic lights so computer-vision systems could learn from ground-truth data.

THEN CHATBOTS NEEDED HUMANS TOO
As the frontier shifted from computer vision to language models, Scale's labor layer shifted with it. OpenAI used specialized Scale labelers in InstructGPT, where people wrote demonstrations and ranked model outputs for reinforcement learning from human feedback — the method the InstructGPT paper formalized as RLHF.

THE DATA-LABELING STARTUP ENTERS THE WAR ROOM
The Pentagon's Defense Innovation Unit awarded Scale the prime contract for Thunderforge, a program using AI to support U.S. military planning and operations. By then Scale had moved far beyond annotation into model evaluation, deployment and decision-support systems.

META PAYS $14.3 BILLION — AND TAKES WANG TOO
Meta invested $14.3 billion for a 49% stake in Scale, valuing the company at about $29 billion. Wang left the CEO job to join Meta, and weeks later was put in charge of Meta Superintelligence Labs as chief AI officer.
