For coding company Replit, the dark days of stagnant growth, burning cash and layoffs ended with the successful launch of its Agent and a strategic pivot to using natural language prompts for building mobile apps.  

The once-struggling, 10-year-old startup has become one of the biggest names in the very hot "vibe coding" trend, named for its intuitive, freer-style method. Replit's annualized recurring revenue jumped in less than a year from $2.8 million to $150 million by late 2025, and it's projected to be on track for $1 billion by 2027. 

Valuation for the Foster, California-based company has grown quickly, from $3 billion in September 2025 to $9 billion in March 2026, with a $400 million Series D financing led by previous investor Georgian Partners in Toronto, along with repeat backers Andreessen Horowitz, Coatue and Y Combinator, and others. 

The CEO and founder behind Replit's turnaround is Jordanian-American software engineer Amjad Masad. His vision for opening software development to the masses turned his startup into a market leader in AI coding. Previously, he was a founding engineer at coding instructor Codecademy and a tech lead at Facebook. He gained an edge in entrepreneurship after his startup got into accelerator and venture firm Y Combinator, after three rejections.

The high-growth company Masad founded in 2016 is unprofitable while maintaining its large war chest of funding and a niche market lead in generative AI. Its successful AI-powered Replit Agent and several newer versions over the past year pushed the company past 50 million users and 500,000 professional business customers, including at companies such as Zillow, Labcorp, Atlassian, PayPal and Adobe. In all, more than 85 percent of Fortune 500 companies have used its coding tools, according to Replit. 

AI coding grew to $4.2 billion of the $19 billion AI applications market in 2025 while enterprise AI spending surged to $37 billion, growing faster than any software category, according to a Menlo Ventures report. 

This year's No. 1 Disruptor Anthropic is shaking up the market with the AI coding assistant Claude Code, which was generating $2.5 billion in estimated annual revenue by early 2026. Replit also competes with fellow Disruptors Lovable and Cursor. Cursor is more dominant in enterprise and professional markets, and Lovable is the faster-growing tool for non-technical users. Replit has broad reach across beginners, educators and enterprises alike.  

Expanding its footprint, Replit recently signed a multi-year partnership with Google Cloud to go up-market with enterprises, signed a collaboration agreement with Microsoft to bring vibe coding within Azure cloud computing, and debuted a feature for creating and publishing apps on Apple.

As Replit pushes further into the enterprise, Masad says that dissatisfaction with current software tools is aiding its growth. "This one-size-fits-all SaaS software … a lot of people are really tired and kind of frustrated with it, because they keep the data in siloes and people just want to customize," Masad told CNBC's Julia Boorstin. "I was at an investor conference today and a customer was telling us how they built a custom CRM, 'all the features Salesforce couldn't give me,' they said. So a lot is about creative custom solutions and net new apps that wouldn't have otherwise been created."

Masad also cited examples of one-person startups growing to lofty valuations in a relatively short period of time due to the assistance of Replit. "One employee … one billion-dollar company. That wasn't possible before," he said, adding that a founder can use Replit to have 20 AI agents running at once while they bootstrap a company.
