Company profile

researched Aug 2026

Turing is a Palo Alto, California-based company that began as a platform for sourcing, vetting and hiring remote software engineers and has since added two AI-focused business lines. Its original product used automated, machine-learning-driven assessments (marketed as "Deep Vetting") covering technical skills, soft skills and English proficiency, matching engineers to companies through what the company described as an Intelligent Talent Cloud. That business grew during the COVID-19 pandemic as demand for remote hiring tooling increased, and shifted over time from individual placements toward managed engineering teams sold to enterprises.

Since 2022, Turing has organized work with large populations of engineers who contribute code used in training large language models, a division the company calls "Turing AGI Advancement." A second line, "Turing Intelligence," builds generative AI applications and services on top of foundation models for enterprise customers. Management has described the talent-sourcing business as continuing alongside the AI lines rather than being replaced by them. As of March 2025 the company said it worked with roughly 4 million coders worldwide while employing a number in the hundreds.

Founding story

According to an interview with co-founder Jonathan Siddharth, the idea originated in 2014 while he and Vijay Krishnan were running a prior AI company, Rover. After investors declined to fund Rover's Series A because it lacked a mobile app, the pair struggled to hire mobile engineers in Silicon Valley, where hiring was costly and slow relative to competing with large technology employers. They instead recruited remote engineers in lower-cost geographies, shipped the app and subsequently raised the Series A, concluding that talent should be sourced globally. The company was named after Alan Turing, with the founders citing the Turing Award and the Turing Test as associations with engineering excellence and AI; it initially used the domain TuringAI.net before moving to Turing.com to avoid being perceived as supplying only AI talent.

Business model

Turing sells to companies rather than to engineers, operating three related lines: sourcing and managing vetted remote software engineers (increasingly as long-term managed teams rather than gig placements), organizing large distributed engineer pools to produce code and related data for foundation-model developers, and building generative AI applications and services on top of LLMs for enterprises.

Revenue comes from enterprise engagements across the talent, model-training and AI application lines. As of March 2025 the company reported roughly $300 million in annualized revenue run rate, up from $167 million when the Series E was priced, and said it had been profitable for about a year. The split between business lines was not disclosed.

Traction

As of March 2025, Turing reported working with about 4 million coders globally, roughly $300 million ARR, approximately one year of profitability, and employees numbering in the hundreds. Earlier reporting cites a developer pool that grew tenfold and revenue that rose fourfold between 2020 and 2022, and by 2026 a platform connecting over 3 million developers across 150 countries.

Latest developments

In March 2025 Turing announced a $111 million Series E at a $2.2 billion valuation, led by Malaysia's sovereign wealth fund Khazanah Nasional Berhad, and said it would use the capital to add customers, broaden use cases and expand R&D and go-to-market across its talent, AGI Advancement and Intelligence lines.

▸Full profile — market position, technology, go-to-market, geography, history, risks & controversies

Market position

Turing reached unicorn status in 2021 at a $1.1 billion valuation and doubled that to $2.2 billion in March 2025, having raised $225 million to date. It is described as a key coding provider to OpenAI and other LLM producers and as a multi-billion-dollar competitor to legacy talent platforms.

Turing positions itself against traditional outsourcing, offshoring and management-consulting models by using software and AI in place of manual recruiting and HR overhead, and against gig marketplaces by focusing on long-term, full-time engineering engagements and managed teams. Its role as a supplier of engineering work used in LLM training gives it a position adjacent to foundation-model developers that talent marketplaces generally do not hold.

Technology

The platform relies on automated, machine-learning-based vetting of engineers, assessing technical ability, soft skills and English proficiency, and building developer profiles that the company says draw on more than 20,000 data points. Turing later applied generative AI within recruiting and delivery workflows, including real-time code-quality and productivity monitoring, and patented an Automated Technical Vetting Engine that uses LLMs for live coding interviews.

Go-to-market

Turing sells directly to enterprise buyers and foundation-model companies, with proceeds from its 2025 round earmarked for scaling R&D plus sales and marketing across all three business lines and broadening use cases. The company also invests in organic and paid marketing to build brand awareness around the Turing.com domain.

Foundation-model developers such as OpenAI, companies building applications on top of LLMs, and enterprises hiring engineering capacity; named clients have included Coinbase, Dell and Disney.

Geography

Headquartered in Palo Alto, California, with a globally distributed engineer network spanning many countries; expansion targets after 2021 included Latin America and Southeast Asia.

History

Turing was founded in Palo Alto in 2018 by Jonathan Siddharth and Vijay Krishnan, bootstrapped at first and then backed by a $2.2M seed round. Remote-first hiring demand in 2020 accelerated growth, with a $32M Series B in December 2020 led by WestBridge Capital funding operational scaling and global marketing, and a shift from single placements to managed teams. A $75M Series D in late 2021 led by WestBridge and StepStone valued the company at $1.1 billion as it expanded into Latin America and Southeast Asia. In 2022, Siddharth was invited to a meeting at OpenAI, which asked Turing to help generate code for training data after researchers found that code improved model reasoning; this became a new business line. Turing launched 'Turing Services' in 2024 to embed generative AI into the software development lifecycle, and in 2025 secured a patent for an 'Automated Technical Vetting Engine' using LLMs for live coding interviews and was placed on the Forbes Cloud 100. In March 2025 it raised a $111M Series E at a $2.2 billion valuation.

Risks & controversies

Coverage notes that Turing faced demand headwinds in 2023 as large technology firms introduced return-to-office mandates, prompting a shift toward hybrid models. The company's newer growth is concentrated in serving foundation-model developers, and it has not disclosed how revenue is distributed across its business lines.
