Vibe coding startup Emergent Labs Inc. today announced that it has closed a $70 million funding round led by Khosla Ventures and SoftBank Vision Fund 2.

The Series B deal comes only three months after the company’s previous raise. According to TechCrunch, it tripled Emergent’s valuation to about $300 million.

The strong investor interest in the company is presumably connected to its rapid growth. Emergent, which maintains offices in India and San Francisco, says that its vibe coding platform has drawn more than 5 million users since launching seven months ago. The company is generating more than $50 million in annualized recurring revenue and expects to double that by April.

Emergent’s platform enables users to generate software by entering prompts into a chat box. It’s capable of generating websites, mobile apps and desktop programs. After generating the code requested by a user, the platform scans it for bugs and automatically fixes any issues it finds.

Emergent says its platform is useful for not only nontechnical workers but also professional developers. A company’s software team can use the platform to generate working prototypes of new features faster than would be possible manually. Such prototypes make it possible to identify edge cases, or infrequently occurring bugs, and collect customer feedback.

Developers can coordinate their work with interface designers through a built-in collaboration tool. Once both the code and design of an application are ready, they can use an AI agent to generate documentation. There’s also a GitHub integration that makes it possible to save Emergent-generated code to a company’s production repository.

Administrators can define access policies to regulate which developer can edit what Emergent project. According to the company, it’s possible to implement similar controls for an AI-generated application’s end-users. Emergent provides the ability to create a login workflow for users, hash their account credentials and define rate limits.

The platform lends itself to a range of use cases. An enterprise can use Emergent to build simple applications that automate manual work for employees. Startups, meanwhile, can have it generate commercial software products. Emergent provides integrations with payment platforms such Stripe that enable users to monetize their AI-generated software.

“Emergent is growing at a pace we rarely see because it is tapping into a segment that has never been served,” said Khosla Ventures founder Vinod Khosla. “When barriers to software creation fall this quickly, behavior changes across industries, not just within the technology sector.”

Emergent will use the proceeds from its funding round to grow its headcount and speed up product development initiatives.
