CommonLayer is the reasoning layer between organizational intent and engineering execution.

Your architecture knowledge, at the point of decision.

Every engineering organization has architectural knowledge. The challenge isn't capturing it - it's ensuring the same intent reaches every decision.

CommonLayer brings your organization's architectural context into the engineering workflow — surfacing the right information in their own vocabulary at the moment a decision is being made.

Purpose-built for your architecture. Grounded in your systems.

COMMONLAYER

HOW IT WORKS

PRIMARY — THE WORKING PATH

Knowledge that travels to where the decision gets made.

Enterprise Architecture captures the structure of your organization - its systems, services, dependencies, and governance. CommonLayer carries that understanding into engineering workflows at the moment a decision is being made.

01 — INTAKE

Architecture is captured once

Your principles, services, and dependencies are structured and made queryable, tied to real systems, not buried in slide decks.

02 — QUERY

Engineers ask in their workflow

No new tool to learn. /define, /service, /change, and /eval meet engineers at the point of decision, in language they already use.

03 — GROUND

Every check ties to a named principle

Checks run against your org's own principles and service records, each with a reference code, a defined statement, and a severity.

04 — IMPROVE

Corrections compound

When an engineer flags something off, that correction is captured for review and incorporated into the knowledge store. The system improves with every real decision it touches.

COMMAND SURFACE

Four commands. One source of truth.

CommonLayer doesn't ask engineers to change how they work. It shows up as four commands inside engineering workflows — and as a structured governance layer that architects can query directly.

/define

Anchors the organization

In a vocabulary common to everyone, not a generic glossary.

/service

Clarifies the landscape

Owners, dependencies, and inherited principles - what's actually known about a service.

/change

Activates before you ship

Evaluates downstream impact before a change ships, not after it breaks something.

/eval

Accelerates toward the objective

Scores a service against your governance principles, named and flagged.

WHY IT'S TRUSTWORTHY

ALTERNATE — THE VERIFICATION PATH

Architecture-specific grounding, benchmarked, not assumed.

CommonLayer applies grounded reasoning to your organization's architectural knowledge - derived from your real systems, checked against your own principles, and present at the moment engineers need it. Benchmarked across 1,186 queries, three AI models, and three conditions, scored across seven dimensions. Measured on purpose-built evaluation datasets; real-world validation is underway with design partners.

2× accuracy

Direct LLM baselines without organizational context score less than half as well — measured against CommonLayer across the full test corpus.

2× risk detection

CommonLayer surfaces roughly twice as many architectural risks as raw LLM tools under constructed sparse-data scenarios. The system holds up when the data isn't perfect.

Zero hallucinations

Across all 1,186 records, three model backends, two test tracks, and seven scoring dimensions.

DESIGN PARTNER PROGRAM

We're working with a small number of design partners.

We're looking for a handful of engineering organizations to shape the product directly, in exchange for early access and a direct line to the build.

→ Direct access to the founder, not a sales team
→ Product shaped around your real architecture, not a generic demo
→ Design partner access ahead of general availability
