AI has eaten the internet, data labeling is so over, and $30 trillion of human work is on the verge of automation. Jonathan Siddharth, Founder & CEO of Turing, joins Sourcery to break down the power shift in AI training — from commodity data labeling to expert research — positioning Turing apart from AI data providers like Scale AI, Mercor, & Surge.

Turing has become a hidden force in the AI race, hitting $300M in ARR in 2024 (~3x YoY), achieving profitability, and raising $111M at a $2.2B valuation in March. That growth cements its position as one of the fastest-growing AGI infrastructure companies.

Today, frontier labs like OpenAI, Anthropic, Meta, Google, Microsoft, Nvidia, & Amazon rely on Turing for the frontier data that pushes AI forward across the four pillars of superintelligence:

• Multimodality

• Reasoning

• Tool use

• Coding

We explore Turing’s expansion into the enterprise, closing the “gap” – where Fortune 500s in finance, insurance, and pharma are racing to build proprietary intelligence on their own data, creating durable moats in the $30T knowledge work economy.

PS Jonathan also explains how labs like OpenAI train models:

• Pre-training on filtered internet corpora (Common Crawl, GitHub, books, video)

• Post-training with supervised fine-tuning (human Q&A datasets)

• Reinforcement learning (RLHF + verifiable domains) to align models with human preferences

• Model-breaking data from Turing’s 4M+ engineers to close gaps and advance systems like GPT-5
