The Science of Automation
Most automations break because they were built for the happy path only. PURIST builds for production idempotent, error-aware, self-hosted and fully observable from day one.
Trigger-first design
Every automation starts with a precise trigger a webhook, a schedule, a database event or a form submission. We define the exact condition before writing a single step. No ambiguous "when something happens" logic.
Idempotent by default
Every workflow we build handles duplicate events gracefully. If the same trigger fires twice, the result is the same no double-sends, no double-records, no corrupted data.
Error-first architecture
We design the failure path before the happy path. Every workflow has a dead-letter queue, an error branch and an alert. You never find out about a failure from a client.
Self-hosted infrastructure
Your automations run on a dedicated VPS not a shared SaaS cloud. Your data never touches a third-party automation platform. Full control, full ownership.
AI at the decision layer
Claude Opus handles classification, extraction, drafting and routing not as a bolt-on, but as a native step in the workflow. Latency under 80ms. Deterministic output with structured prompts.
Observable and auditable
Every workflow execution is logged with input, output and duration. You can audit any run. We can replay any failure. Nothing is a black box.
