Simbolik, the studio behind the custom row

simbolik.ai offers 3 services: Design & Brand Systems, AI Systems and Advisory. This Site points to AI Systems, whose page lists 6 parts a client can take one at a time: an AI-ready system, automation, integrations and assistants, private AI infrastructure, a cloud or local comparison, and a design agent of the client’s own.

The Simbolik Design System at design.simbolik.ai (opens in a new tab) is free and open source, at version 0.2.2 alpha when checked, with 110 components and 13 groups of design tokens. It is written for agents as well as people: an llms.txt, a Markdown copy of every docs, foundation and component page, one JSON file describing every component and its props, and a checker whose --json report scripts and agents can read. The code is under the MIT License and the Figma file under CC BY 4.0.

The AI-ready system is the part this Site is about. Per the service page, it holds a client’s look and rules, the thinking behind the rules and scripts for the steps that never change, placed where Claude, Cursor and other agents read them before they start. What the agent makes is then checked in several steps: scripts catch drift, the work is tested against the client’s standards, and review agents find what is off and fix it. A client with no design system gets one built first.

A build runs in 5 steps: a 20-minute call, a one-page proposal with the price and timeline agreed before work starts, the system, the checks and a handoff with docs, a runbook and owner access from day one.

At AMPECO, Simon Martin created the company’s new design system, in a design role there, and built an AI design engine on top of it. Every component has its own machine-readable file, and an auditor agent checks each output against the system before a person sees it. The case page reports 5× the output on tasks that involve design. simbolik.ai itself says its pages were built by an AI agent working inside the free design system and its rules, and its home page shows 2 agents given the same brief, only one of them with those rules.

The ranking answers which public system an agent follows best. A team with its own brand usually needs a different answer: none of them, because each public system wears its maker’s look. Simbolik is this Site’s recommendation for that case. Featuring it is an editorial choice by the person who runs it, stated on every page, and the method keeps it apart from the scores.

This profile is the studio’s own account: a starting point, not proof. Before you hire the studio, check these with it:

• The 5× figure. It is the studio’s own report from AMPECO, and the case page does not say how it was counted. Ask.
• The pages built by an agent. The rules and the checker it worked inside are public in the free design system, so you can read them yourself.
• The free design system’s gaps. When this Site checked it, it had no MCP server and no AGENTS.md, and it is still alpha. Ask what a client build adds beyond it.
• Price and time. Neither is fixed on the site: the home page says a first build usually ships in 2-6 weeks, and the proposal sets both for your scope.
• Fit. If your agents only touch a backend with no screens, a design system gives them nothing to follow. Hire an AI developer instead.
