Progressical

Harness engineering for AI products

Your AI feature shipped.Now harden the harness.

Progressical diagnoses where production LLM features lose signal, rebuilds the parts that matter, and leaves your team with an eval set, a PR, and a harness it can keep extending.

Audit-first access

Start with the layeryour users actually experience.

Progressical works on the harness around your LLM: retrieval, prompt assembly, conversation memory, tools, validation, retries, and fallbacks. Join the list for early audit availability.

Harness audit

Two weeks of trace review, failure-mode taxonomy, and a prioritized fix list for the LLM feature that matters most.

Rebuild as a PR

Retrieval, prompt assembly, memory, validation, and fallback changes delivered inside your codebase.

Eval set included

A scored set of real production cases so your team can measure model swaps and prompt changes before users do.
