Beam

Beam is an AI-native cloud platform providing serverless infrastructure for deploying and scaling AI and machine learning workloads — enabling ML engineers and developers to run GPU-accelerated inference, fine-tuning, and batch processing jobs without managing underlying cloud infrastructure, with automated scaling from zero to peak load and back. Founded in 2021 in New York City by Luke Lombardi and Eli Mernit, Beam raised $4 million from investors including Tiger Global Management and Uncorrelated Ventures, reaching $1 million in revenue by December 2024 with a 5-person team.\n\nBeam's platform abstracts the infrastructure complexity of running AI workloads on GPU clusters — developers define their compute requirements (GPU type, memory, runtime), write Python functions, and deploy them as serverless endpoints without configuring Kubernetes clusters, managing GPU drivers, or handling auto-scaling manually. The platform handles cold-start optimization for AI models, persistent storage for model weights, and cost management through intelligent scaling. This serverless GPU model is particularly valuable for AI applications with variable traffic patterns where paying for always-on GPU capacity wastes money.\n\nIn 2025, Beam competes in the AI infrastructure market with Modal Labs, Replicate, Banana (ML inference), and cloud providers' own managed ML services (AWS SageMaker, Google Vertex AI, Azure ML) for serverless AI compute. The market for specialized AI inference infrastructure has grown rapidly as the number of teams deploying AI models to production has expanded dramatically. Beam's lean team and capital efficiency ($1M ARR with 5 people and $4M raised) position it as a high-efficiency operator in this space. The 2025 strategy focuses on expanding GPU availability across regions, adding more pre-optimized inference runtimes for popular model architectures (Llama, Stable Diffusion, Whisper), and growing developer adoption through improved tooling and documentation.
