# Modal

> Modal is a serverless cloud platform that lets developers run compute-intensive AI and data workloads - inference, training, fine-tuning, batch jobs, and sandboxed code - without managing infrastructure. Built from scratch in Rust with a custom container runtime, file system, and GPU memory snapshotting, it delivers sub-second cold starts and elastic autoscaling from zero to thousands of GPUs, billed by the second. Founded in 2021 by Erik Bernhardsson and Akshat Bubna, the New York-based company reached roughly $300M in annualized revenue and raised a $355M Series C in 2026 at a $4.65B valuation.

- **Founded:** 2021
- **Headquarters:** New York, New York, United States
- **Founders:** Erik Bernhardsson (Co-founder & CEO), Akshat Bubna (Co-founder & CTO)
- **Team size:** ~120 employees
- **Products:** Modal SDK, Inference, Training & Fine-tuning, Sandboxes, Batch
- **Notable:** Reached ~$300M in annualized revenue in April 2026, up from ~$119M at year-end 2025., Raised a $355M Series C at a $4.65B valuation in May 2026., Built every layer of its AI cloud - container runtime, file system, scheduler, GPU memory snapshotting - from scratch in Rust.

## Products & services

- **Modal SDK** — Python-native cloud development where developers define logic and hardware requirements in a single codebase, attaching GPUs and scaling with simple decorators.
- **Inference** — Low-latency deployment and autoscaling for LLMs, audio, image/video generation, and multimodal models across GPU types, with web endpoints and observability.
- **Training & Fine-tuning** — Single- and multi-node GPU training, reinforcement learning, and parallel hyperparameter sweeps on B200, H100, and A100 hardware.
- **Sandboxes** — Secure, ephemeral, gVisor-isolated environments for running AI-generated code, coding agents, RL rollouts, and GPU-accelerated research.
- **Batch** — Massively parallel batch processing and distributed job queues for embeddings, data jobs, and bursty workloads.
- **Notebooks** — Collaborative, GPU-backed notebooks for experimentation and research.
