Grafana Labs CEO Raj Dutt.Brian GoodmanWhen Nvidia, the $4.4 trillion juggernaut that makes the GPU chips undergirding the AI frenzy, needs to monitor its systems for threats and suspicious activity, it turns to a small startup named Grafana Labs to help it scour access logs and analyze vulnerabilities. And the chip maker isn’t alone. Uber, Anthropic and Adobe are among the other giants tapping Grafana’s tools — like a dashboard for operations across an entire business.Now $6 billion-valued Grafana, known as an observability platform, on Tuesday said it hit $400 million in annualized revenue. The uptick in sales has been thanks in part to the growth of Grafana Cloud, which lets customers use its platform without setting up their own infrastructure like servers or storage, CEO Raj Dutt told Forbes. The need for good observability services has ballooned in the AI era, especially as vibe coding from generative AI models has become more common. As people increasingly rely on AI to write code and build products, it’s become harder to keep track of what’s going on under the hood, when it’s being done and who’s doing it, Dutt said. “Software today is starting to look more like a living organism,” said Dutt. “It’s being built and shipped faster than ever — sometimes sloppily. That makes it critical to understand how your app is performing in production.” Grafana also said it had completed a tender offer of up to $150 million, which allows new or returning investors to purchase existing shares from employees or early investors. The transaction was led by the Ontario Teachers’ Pension Plan, with participation from Sapphire Ventures and Tiger Global. Existing investors including Lightspeed Venture Partners, Sequoia and CapitalG, the growth stage venture firm of Google parent Alphabet, also took part. Grafana declined to disclose a new valuation.“Software today is starting to look more like a living organism.”
