You can deploy experiments without tweaking live code and have our developers by your side to integrate feature flags in your development process. This will only show features to a small group initially before releasing it and you will have full control over the lifecycle of any feature based on their performance.

Single page applications

It can be difficult to figure out how to enable the testing code in single page applications. We simplify that process and we get it done with the help of the developers skilled in React.JS and Angular.

The BrillMark Process

Interested in working with BrillMark? Our process is designed to seamlessly integrate with your team and your campaigns.


Website experimentation starts with auditing your website to identify critical areas and then creating improvement strategies to be tested against the control. This can be done by a CRO agency or your own in-house team. Once you have your testing requirements in place, it’s time for BrillMark to take over.


Our role starts when you decide what are the requirements and parameters for your website experiment. Our experts will design a technical specification for the proposed test, asses the approximate number of hours required, and send you an estimated quote for your approval.


Once the technical specification has been approved, our team will develop the test locally, move the test to testing platform of your choice, and apply the optimal platform-specific settings afterwards. Next, the developed test is sent to our quality assurance department for rigorous review, and once test acceptance criteria is finalized, and the test is sent to you for final approval.


Once you’ve reviewed and approved the developed test, it’s time to go live! We will monitor the tests closely for 24 to 48 hours to ensure that the test is performing as designed and that all goals and metrics are being tracked correctly.

“Working with BrillMark to help our CRO agency has been a fantastic experience. The team is responsive, thorough, and act as an extension of our in-house team. I highly recommend them to anyone looking for quality development resources”
