Turing
AI-powered staffing platform supplying vetted developers and eval data to AI labs.
Turing has real revenue and lab access, but its growth has stalled while cheaper, less-tied rivals like Surge AI and Mercor keep growing.
Turing sells data labeling and evaluation services to companies building AI models like OpenAI, Anthropic, and Google. It is hard to copy because the major labs trust Turing to stay neutral and not favor any one company, and Turing has direct relationships built over years. However, other companies like Surge AI and Mercor offer the same neutrality with no real barriers stopping them from taking Turing's customers, and the labs themselves can cheaply build these teams in-house instead of hiring outside help. The real test comes in late 2026: if Turing's revenue stays flat and its next funding round values the company at or below $2.2 billion, it means the slowdown is permanent, not temporary.
Turing closes a Series F at or below the $2.2B Series E valuation. Would indicate investor confidence in growth has weakened.
A frontier lab (OpenAI, Anthropic, Google, Meta) takes an equity stake in Surge AI or Mercor. Would repeat the Scale AI pattern and show labs bypassing neutral vendors like Turing.
- $300M+ ARR, roughly flat for 12 months
- $111M Series E at $2.2B valuation
- Rival Mercor: $350M raise at $10B valuation
- ARR plateaued near $300M from January to December 2025 after prior 3x annual growth.
- Largest customers are frontier labs able to insource or shift vendors overnight, as Meta did with Scale.
- No confirmed Series F 16+ months after March 2025 Series E despite rivals raising or restructuring.
- Legacy remote-developer-staffing business eroding due to AI coding agents like Cursor and Claude Code.
- Conflicting HQ listings (Palo Alto vs San Francisco, Jul 2026) suggest unresolved corporate transition.
| Rival | Direction | Evidence |
|---|---|---|
| Scale AI | gaining on | Meta's 49% stake in Scale (Jun 2025) and Scale's 14% headcount cut (Jul 2025) opened share for neutral vendors like Turing |
| Surge AI | losing to | Bootstrapped 110-person Surge reportedly surpassed Scale's ~$870M 2024 revenue, favored by Meta post-deal (2026) |
| Mercor | losing to | Mercor raised $350M at $10B valuation in Oct 2025, ~5x Turing's $2.2B Series E valuation |
| Microsoft | contesting | Microsoft launched its own enterprise AI Agent Marketplace in Sep 2025, rivaling Turing's HUMAIN ONE deal |
| OpenAI, Anthropic, Google, Meta | contesting | All are Turing customers with in-house data/eval teams capable of insourcing, as Meta did with Scale in Jun 2025 |
- Is Turing profitable in 2025?
- Yes. Turing announced on January 28, 2025 that its annualized revenue run-rate nearly tripled to about $300M in 2024 and that the company achieved profitability that year, a status it says continued through its December 2025 update.
- Has Turing's growth stalled?
- It appears so. Turing reported ~$300M ARR in January 2025 and its own December 2025 blog post said it had merely 'surpassed $300M ARR,' suggesting roughly a year of flat growth after prior 3x annual gains.
- Who owns Turing?
- Turing is privately held and venture-backed. Its March 6, 2025 Series E raised $111M at a $2.2B post-money valuation, led by Malaysia's Khazanah Nasional Berhad, with total funding reaching $225M as of that date.
- Could AI replace Turing?
- Turing's original remote-developer-staffing business is exposed to AI coding agents like Cursor and Claude Code, but its frontier-lab data, evaluation, and RL-environment work for OpenAI, Anthropic, Google, and Meta depends on human expert input those labs still buy rather than fully build in-house as of 2025-2026.
- Who is Turing's biggest competitor?
- Scale AI, Surge AI, and Mercor. Surge AI, with only about 110 employees, reportedly surpassed Scale's roughly $870M 2024 revenue, while Mercor raised $350M at a $10B valuation in October 2025, nearly 5x Turing's valuation.
- Did Turing raise a new funding round in 2026?
- No Series F had been confirmed as of July 14, 2026, more than sixteen months after its March 2025 Series E closed at a $2.2B valuation, according to reporting on Turing's executive hire that month.
