GitBook is a collaborative documentation platform with Git-sync that lets engineering and product teams write, version, and publish beautiful docs from a shared workspace.
GitBook is a documentation platform founded in 2014 and headquartered in Lyon, France, that enables teams to create, manage, and publish technical documentation in a structured collaborative environment. The platform is built around a block-based editor that combines the simplicity of a wiki with deep Git integration, allowing teams to sync documentation directly with GitHub or GitLab repositories and track changes through familiar version-control workflows. GitBook supports internal knowledge bases, public developer docs, and API references, making it versatile for both external developer-facing content and internal engineering runbooks. GitBook differentiates through its clean reading experience, real-time multi-author editing, and AI-powered search that surfaces answers across large doc sets. The platform integrates with tools like Slack, Jira, and linear, fitting naturally into modern engineering workflows without requiring technical setup from non-developer contributors. GitBook raised a $21M Series A in 2021 led by Notion investor Point Nine Capital and has grown a user base spanning thousands of engineering teams globally. The company competes with Confluence, Notion, and Mintlify, positioning itself as the purpose-built solution for developer and product documentation that balances editorial ease with Git-native power.
Serverless GPU cloud platform for AI/ML with Python-native deployment and per-second billing; developer-favorite scaling from zero competing with Replicate and Beam for AI compute.
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).
