Svix is a webhooks-as-a-service platform that enables companies to send, receive, and test webhooks reliably and at scale. The platform handles the infrastructure concerns that typically accompany webhook implementation - automatic retries, security, monitoring, and scalability - allowing engineering teams to offload that work rather than build and maintain it in-house. Svix's JavaScript library alone is downloaded over one million times per month.
The platform is used across a broad range of organisations, from early-stage startups to Fortune 500 companies. Named customers include Brex, Replicate, TaskRabbit, and PagerDuty. By Svix's own account, it delivers billions of webhooks annually.
Svix has raised $11 million in funding and is backed by Y Combinator, Andreessen Horowitz (a16z), and Aleph. The company positions its infrastructure as the foundation for turning software products into real-time data pipelines - a growing requirement as API-driven architectures become standard across the industry.
