Modal Secures $750M Series D at $15.75B Valuation as AI Cloud Run Rate Tops $1B

The generative AI boom has exposed a critical bottleneck in software development: traditional cloud infrastructure was not built for the massive, bursty compute demands of large language models. Developers often spend more time configuring Kubernetes clusters and managing GPU provisioning than writing actual code. To bridge this gap, New York-based Modal has secured $750 million in a Series D funding round led by Accel, catapulting its post-money valuation to $15.75 billion.

Founded by former Spotify engineering leader Erik Bernhardsson, Modal provides a serverless execution environment specifically designed for AI and data teams. Instead of renting static servers, developers use a simple Python decorator to instantly deploy code to the cloud, scaling from zero to thousands of GPUs in seconds. The platform handles the underlying complexity—including a custom file system and container runtime—while charging users strictly for the exact compute cycles consumed.

The massive Series D arrives just five months after Modal's $355 million Series C, reflecting explosive enterprise adoption across the AI sector. The company recently crossed $1 billion in annualized run rate, with platform usage growing more than 15x year-over-year. As AI shifts from experimental chatbots to production-grade enterprise applications, Modal is positioning itself as the foundational compute layer for modern software development.
