The VC Read
Meta's ~$14B for half of Scale was really an aqui-hire of Alexandr Wang plus an insurance policy on data supply — and it quietly handed Scale's biggest gift to its competitors. Every rival lab now has a reason to move spend to Surge or Mercor rather than fund a Meta affiliate. The lesson for founders: a strategic at 49% can be worth more in cash than control, but it can also strand the rest of your market. Watch whether Scale's revenue holds as labs diversify away.
How Scale AI makes money
Scale sells the training and evaluation data that frontier AI runs on — human labeling, RLHF (reinforcement learning from human feedback), red-teaming, and model evaluation — to the major AI labs and enterprises, plus a growing government and defense business and an applications arm.
The Meta deal reshaped the company: by taking ~49% and hiring away founder Alexandr Wang, Meta secured priority access to Scale's data pipeline, while rival labs now weigh whether to keep buying from a Meta-aligned vendor. That tension — neutral data foundry vs. Meta affiliate — is the defining question for Scale's next chapter.
Competitors
- Surge AI — The largest pure-play data rival, now benefiting from Scale's Meta entanglement.
- Mercor — Expert-marketplace model; Scale sued it over trade secrets.
- Labelbox — Enterprise annotation platform.
- Turing / Micro1 — Talent-driven data and evaluation.
