What is Fastn.ai?
Fastn.ai is a composable middleware platform that enables SaaS companies and AI agent builders to embed integrations and automation into their products without the overhead of building or maintaining them from scratch. By providing a unified integration layer, Fastn eliminates the need for custom code for each API or legacy system, allowing teams to focus on core product development.
At its core, Fastn offers three key capabilities: Tool Orchestration, Tool Composition, and Performance Optimization. Tool Orchestration intelligently filters tools and schemas based on the intent of an agent's task, reducing context bloat, minimizing hallucinations, and cutting token usage. Tool Composition learns from frequent tool chaining patterns and automatically batches and merges tool calls, lowering latency and API costs. Performance Optimization caches results and adapts schemas to improve reliability and reduce compute waste. Additionally, Fastn provides full transparency and auditability by tracking usage, cost, and reasoning paths, while enforcing RBAC, compliance, and prompt safety for secure, governed execution.
With access to over 1,000 pre-built tools and the ability to create infinite custom ones via a single MCP server, Fastn is designed for demanding enterprise security requirements, including HIPAA compliance. Use cases include connecting APIs, legacy systems, enterprise workflows, and enabling AI agents to perform complex tasks autonomously. Fastn is trusted by customers and partners, and offers features like Fastn Automation, Fastn Data Sync (coming soon), and Fastn Agent Auth (coming soon). It is ideal for any organization looking to accelerate integration delivery, reduce maintenance burden, and enhance the capabilities of their AI-driven products.
