Cognition AI raises $2B at $48B valuation, nearly doubling its value in just four months

Cognition AI has raised $2 billion at a $48 billion valuation, nearly doubling its value in four months and making the maker of Devin one of the most highly valued private AI companies in the software industry.

The Series E round was led by new investors Andreessen Horowitz and Accel, with existing backers Founders Fund, General Catalyst and Avenir participating. The unusually large syndicate includes Benchmark, Bessemer, Kleiner Perkins, Greylock, Lightspeed, Altimeter, Bond Capital, T. Rowe Price, Lux, 8VC, DST and Bain Capital Ventures, among others.

“Cognition has raised over $2B at a $48B valuation. The round was led by new investors Andreessen Horowitz and Accel, alongside existing investors Founders Fund, General Catalyst, and Avenir,” the Devin maker said in a blog post.

The headline number is huge. The speed behind it is even more striking.

Cognition raised $1 billion at a $26 billion valuation in May. Four months later, investors are valuing the company at $48 billion, an increase of roughly 85%. Cognition says its run-rate revenue climbed from $492 million to nearly $900 million over the same period.

Those figures are company-reported run-rate numbers, rather than audited annual revenue, but they help explain why investors were willing to reprice Cognition so aggressively.

From AI coding assistant to autonomous engineer

Cognition emerged from stealth in March 2024 with Devin, which it introduced as the “world’s first AI software engineer.” The pitch went beyond autocomplete or code snippets. Devin was built to plan engineering tasks, write code, test its work, and complete portions of software projects with limited human intervention.

That distinction has become far more significant as AI coding moves from assisting developers to taking responsibility for larger chunks of engineering work.

“We started Cognition in 2024 to change that and build the future of software engineering. We believed engineers should operate more like architects and delegate execution to swarms of agents. Together, engineers and their Devins could dramatically expand the world’s capacity to build great software and solve hard problems,” Cognition said in a statement.

The company says Devin is now being used across engineering teams at NVIDIA, GE Aerospace, Citi, Mercedes-Benz and AI infrastructure startup Modal.

Cognition’s growth comes as software development emerges as one of AI’s clearest enterprise markets. Coding has something many corporate AI applications still lack: measurable economics. Companies know what engineers cost, how long projects take, and how much software they need to ship. If an AI agent can meaningfully increase developer output, the financial case can be easier to quantify.

That opportunity has attracted fierce competition. Anthropic, OpenAI and Google are pushing deeper into coding, alongside developer platforms and a growing field of AI-native startups. Cognition’s $48 billion valuation is effectively a multibillion-dollar bet that Devin can become a lasting software platform rather than another capability absorbed into larger AI systems.

Cognition is building beyond Devin

The company has already moved beyond a single-agent product.

Cognition acquired Windsurf, the enterprise-focused AI coding platform, a little over a year after Devin’s debut. The deal followed Google’s $2.4 billion agreement with Windsurf to license its technology and bring key members of its engineering team into Google.

The acquisition gave Cognition another foothold in the developer workflow and signaled a broader ambition: own more of the environment where AI agents and human engineers build software together.

TechStartups first covered Cognition in March 2024, when the startup unveiled Devin and made the provocative claim that an AI system could function as a software engineer rather than merely assist one.

A lot has changed since then.

Cognition is now valued at $48 billion, says it is approaching $900 million in run-rate revenue, and has raised more than $2 billion. The question facing the company is no longer whether developers will use AI to write code. That debate is largely settled.

The $48 billion question is how much of the software-development stack Cognition can own before everyone else catches up.
