About

Stainless is a developer tools company founded in 2022 that automates the generation of high-quality, idiomatic API client SDKs from OpenAPI specifications. The company addresses the significant engineering burden of maintaining accurate, well-designed SDK libraries across multiple programming languages like Python, TypeScript, Java, Go, Ruby, and Kotlin. Stainless generates SDKs that include features like pagination, retries, streaming support, and type safety that are difficult to implement consistently by hand. The company is used by notable API companies including OpenAI, Anthropic, Cloudflare, and Stripe, which have used Stainless to generate or improve their official SDK libraries. Building and maintaining SDKs across multiple languages is a hidden cost for API-first companies that can consume significant engineering capacity, and Stainless turns this into a solved problem. The company raised significant seed funding and has built a reputation for producing SDKs with the polish and ergonomics of hand-crafted libraries while eliminating the ongoing maintenance work as APIs evolve.

About

Modal is a serverless cloud computing platform purpose-built for AI and machine learning workloads — providing on-demand GPU compute that scales instantly from zero with per-second billing, container management, distributed training support, and a Python-native developer experience that makes running ML workloads in the cloud feel as simple as running code locally. Founded in 2021 in New York City and backed by Redpoint Ventures and other investors, Modal has grown rapidly as AI development has accelerated demand for flexible, developer-friendly GPU infrastructure.\n\nModal's developer experience is its primary differentiator — engineers write Python functions decorated with @modal.function() and deploy them to the cloud with a single command, with Modal handling container building, GPU provisioning, auto-scaling, and execution. The platform supports training jobs that need distributed compute across multiple GPUs, model serving endpoints that scale to zero when unused (eliminating idle GPU costs), and batch inference jobs that process large datasets. The per-second billing model means developers pay only for actual compute time, not provisioned instances.\n\nIn 2025, Modal competes in the AI infrastructure market with Replicate, Beam, Banana, and major cloud providers' managed ML services (AWS SageMaker, Google Vertex AI, Azure ML) for serverless GPU compute. The market for AI-specific cloud infrastructure has grown dramatically as the number of ML engineers deploying models to production has expanded — traditional cloud providers require significant DevOps expertise to use GPU instances effectively, while Modal's Python-native approach reduces the barrier to entry. Modal has attracted a strong developer following among AI researchers and ML engineers building production AI applications. The 2025 strategy focuses on growing the developer community, adding enterprise features (dedicated GPU capacity, private networking, compliance), and expanding the hardware options available (H100 GPUs, custom accelerators).
