Spirl

Spirl is a non-human identity and access management (IAM) startup that in 2025 rebranded to Defakto (defakto.security); spirl.com now redirects to the Defakto site. The company secures automated systems — workloads, services, CI/CD pipelines, Kubernetes, and AI agents — by replacing static secrets and hardcoded credentials with short-lived, cryptographically verifiable identities built on open workload-identity standards (SPIFFE/SPIRE style). Co-founded by Eli Nesterov (ex-ByteDance infrastructure) and Danny Oliveri, it targets the enterprise gap where organizations run millions of non-human identities protected only by static secrets. Defakto was named a 2025 Gartner Cool Vendor in Identity-First Security. It is a portfolio company of Bloomberg Beta. As of this profile the company publishes a marketing site, blog, and security page but no public developer API, OpenAPI specification, SDKs, CLI, or developer portal — access is via demo request, so there is no API surface to enrich at this time.

Spirl is profiled on the APIs.io network. Tagged areas include Company, Security, Identity, Non-Human Identity, and Workload Identity.

Spirl’s developer surface includes engineering blog, signup flow, support, and 6 more developer resources.
