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.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/spirl: open an issue to ask a question, or submit a pull request to add artifacts.
