BrillMark

Developers for the experiments conversion teams cannot staff

BrillMark provides developers to build and launch website experiments, and its customers are agencies that specialize in conversion rate optimization, in-house growth teams, and brands selling to businesses or straight to consumers, all with test ideas but not the people to build them. The company works remotely from several places, reports a decade of experience, and that it has worked on over 10,000 campaigns and, by its latest count, more than 15,000 experiments for over 200 agencies and brands.

How the testing work is done

Each experiment is hand coded from scratch against a hypothesis, design or ticket, with the aim of matching the original design exactly rather than making visual changes while converting design files. The team works on any testing platform, whether the job is a copy swap or a full-page or multi-step rebuild, including complex API-based tests and campaigns spanning several platforms. Every build is checked across browsers and devices with cross-browser tools and a 20-point quality checklist, and tests are shipped without flicker. The code for each experiment is stored in a repository so the client's own team can maintain and adjust it later.

BrillMark describes the situations in which agencies come to it: a backlog of ideas with nobody to build them, tests too complex for the in-house crew, demand that rises and falls through the year, testing software bought without the people to use it, and a wish to test more without raising the budget. Its answer is to act as an extension of the client's team at a fixed cost, so no extra hiring, onboarding or training is needed.

Development beyond testing

The company also does front-end and back-end development on live sites. That includes Shopify migration, theme development and optimization, WordPress development, and performance work in which it profiles where load time goes, rebuilds templates and asset delivery, and implements technical SEO. Accessibility remediation to WCAG 2.2 AA is made in the theme itself, not added with an overlay.

AI and automation

BrillMark now offers AI-assisted website optimization and custom AI agents and helpdesks for web, WhatsApp and email support, which it says can automate a large share of customer queries. It states that AI speeds up documentation, scaffolding and repeatable work while experienced people remain responsible for experiment logic, architecture, tracking accuracy and final QA. Requests begin with a hypothesis, specification or rough idea, and the team replies with a plan covering the solution, estimated hours, timeline and QA scope. It also publishes guidance on topics such as setting up GA4 with Google Tag Manager.
