AI coding startup Cognition closes $2B Series E at $48B valuation

Young Founders Behind the Latest AI Wealth Creation Story

Cognition, an AI coding company, has announced the completion of a Series E funding round exceeding $2 billion, bringing its post-money valuation to $48 billion (approximately 320 billion RMB). The round attracted over 30 investment institutions, drawing nearly half of Silicon Valley's top venture capital firms.

Lead investors: A16Z and Accel Participating investors: Benchmark, Kleiner Perkins, Peter Thiel's Founders Fund, Lightspeed Venture Partners, DST, General Catalyst, and Nvidia

All three co-founders were born after 1995:

• Scott Wu (CEO) – born 1996
• Steven Hao (CTO) – born 1996
• Walden Yan (CPO) – born after 2000

All three are of Chinese descent and share another commonality: each is a gold medalist at the International Olympiad in Informatics (IOI).

From IOI Gold Medals to Founding a Startup

Cognition's defining characteristic is its exceptionally high concentration of IOI gold medalists. The IOI is a global computer science competition for secondary school students. In China, for example, only four students qualify annually. Earning a medal essentially guarantees admission to top universities worldwide.

Founders' IOI achievements:

• Scott Wu: Three consecutive IOI gold medals (2012–2014), ranked first globally in 2014
• Steven Hao: IOI gold medal in 2014, ranked sixth globally
• Walden Yan: IOI gold medal in 2020, ranked 19th globally

After their IOI successes, all three attended elite universities. Scott Wu and Walden Yan entered Harvard; Steven Hao enrolled at MIT. Scott Wu dropped out of Harvard after two years to pursue entrepreneurship.

According to Scott Wu, the founding team met during their competition years and stayed in touch. In 2022, they began discussing a startup idea, initially considering a Web3 project. However, the rise of large AI models quickly shifted their focus to AI coding, leading to the formal founding of Cognition in November 2023. At that time, Walden Yan was still a Harvard student; he later received the Thiel Fellowship and also dropped out to join the venture.

Devin: The "World's First AI Programmer"

In March 2024, Cognition launched Devin, which it billed as the "world's first AI programmer." The demonstration video showed Devin autonomously reading documentation, identifying bugs, and writing tests. While these capabilities seem commonplace now, at the time other AI coding tools were limited to simple code completion, making Devin's product vision appear remarkably advanced and bold. The launch quickly went viral on social media.

Peter Thiel's Founders Fund immediately wrote a $21 million check at a $350 million valuation. Just one month later, in April 2024, Founders Fund led Cognition's $175 million Series A round, pushing the valuation to $2 billion.

Valuation trajectory: | Round | Date | Valuation | |-------|------|-----------| | Series B | March 2025 | $4 billion | | Series C | September 2025 | $10.2 billion | | Series D | May 2026 | $26 billion | | Series E | September 2026 | $48 billion |

Bringing "996" Culture to Silicon Valley

A key acquisition played a pivotal role in Cognition's rise.

In July 2025, Google acquired Windsurf, a popular AI coding tool, in a "poaching-style" deal. Google spent approximately $2.4 billion to hire Windsurf's CEO, co-founder, and dozens of core R&D staff, but declined to acquire the company's equity or take over operations.

This left Windsurf's remaining 200+ employees in chaos. Cognition stepped in, acquiring Windsurf's product, brand, IP, and remaining team. The transaction price was undisclosed but estimated at under $300 million, including stock payments.

The deal proved highly advantageous. Before the acquisition, Cognition had approximately 10,000 daily active users. Windsurf brought over 350 enterprise clients, hundreds of thousands of daily active users, and a complete IDE product. Two months later, Cognition's valuation jumped from $4 billion to $10.2 billion.

However, the acquisition also made Cognition's "wolf culture" widely known in Silicon Valley. During integration, Cognition gave former Windsurf employees two options: accept nine months' salary as severance, or embrace Cognition's corporate culture.

Cognition's work culture:

• Employees work 80+ hours per week
• Six days in the office, with the remaining day requiring phone availability
• The company explicitly states: "We don't believe in work-life balance here"

In an internal memo, Scott Wu wrote: "We are the underdogs, which demands extreme work standards." He added: "We're often in the office on weekends. Many of our best results come from late-night work. Many of us live in the office."

Cognition is transparent about its culture, stating in recruitment notices: "Don't treat this like a normal company."

On the other hand, Cognition is generous with equity incentives. In the Windsurf acquisition announcement, the company promised all former Windsurf employees would receive financial benefits, and removed equity vesting hurdles to maximize their stake in the deal.

While Cognition has not disclosed specific employee equity percentages, those who stayed are likely well-compensated. With approximately 300–400 employees and a $48 billion valuation, the per-capita average exceeds $120 million.

The 53x ARR Valuation Story

Whether the $48 billion valuation is justified remains a matter of debate.

Cognition and Cursor are both star companies in the AI coding space, founded by young prodigies who dropped out of school. Cursor is more well-known but also faces more criticism. Last month, Elon Musk offered a $60 billion valuation to acquire Cursor, which many still consider a sign of AI bubble.

If you hold that view, Cognition's valuation may seem even more extreme.

In its Series E announcement, Cognition stated that since its previous funding round in May, annualized revenue (most recent monthly revenue × 12) had grown from $492 million to nearly $900 million. This means the $48 billion valuation represents approximately 53x ARR.

By comparison, Cursor's valuation appears more reasonable. Cursor announced in early June that its annualized revenue had exceeded $4 billion, making its $60 billion valuation equivalent to only 15x ARR.

The revenue gap between the two companies matches their brand recognition. Cursor is now widely known among programmers and even beyond. Cognition remains a relatively niche coding agent.

This is partly because Cognition has pursued a B2B strategy since its founding. Early on, it strategically bypassed individual users, using a strict invitation-only system and pricing starting at $500/month, which excluded most individual developers. Instead, Cognition focused on large enterprise clients, including Goldman Sachs, Mercedes-Benz, Citibank, Dell, and even the U.S. Department of Defense. Citibank has reportedly deployed Devin to 40,000 engineers, generating over 100,000 hours of autonomous agent work per week—the largest known agent deployment in the financial sector.

Key differences between Cognition and Cursor:

• Cursor: Positioned as a "coding assistant" that helps programmers complete coding work
• Cognition: Emphasizes "one person managing many autonomous agents," enabling AI to independently handle security, migration, and operations tasks for end-to-end autonomous task delivery

Theoretically, Cognition's approach addresses a larger potential market with higher enterprise willingness to pay, justifying its valuation premium.

However, as AI coding evolves, the two companies are converging. In 2025, Cognition launched a $20/month subscription for individual developers and later introduced a free tier. Meanwhile, Cursor has moved toward Cognition's model, launching cloud-based agents that take over tasks in independent environments, run tests, and return results for human review. In June 2026, Cursor's engineering summary focused on how to run these cloud agents over extended periods.

At this point, simple coding scenarios are increasingly being fully addressed by AI. Both companies are trying to embed themselves more deeply into enterprise software development workflows, competing to become the foundational platform. In this trend, Cognition holds a certain first-mover advantage. The 30+ top VC firms assigning a 53x ARR valuation may have their reasons.
