Permit.io provides authorization as a service with a policy editor, audit logs, and SDKs that decouple permissions from application code for any stack.
Permit.io is an authorization platform founded in 2021 that provides developers with a complete solution for implementing fine-grained access control in their applications. The platform offers a cloud-hosted policy decision point, a visual policy editor for defining roles and permissions, real-time audit logging, and multi-framework SDK libraries for Python, Node.js, Java, and other languages. Permit.io is built on top of open-source policy engines including OPA (Open Policy Agent) and Casbin, providing an enterprise-ready hosted service layer on top of proven open-source foundations. The company raised $7M and targets engineering teams that need to implement permission models ranging from simple RBAC to complex ABAC and relationship-based access control without building policy infrastructure from scratch. Permit.io's developer-first approach includes GitOps integration for managing policies as code and a sandbox environment for testing permission changes before production deployment. The platform serves SaaS companies, enterprise applications, and multi-tenant platforms that require auditable, testable access control that can evolve as product requirements change.
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).
