Brillmark Dev Package
Non-AB Testing Developer
Team Composition
Full-Service A/B Testing Experts – Enjoy a dedicated crew of project managers, developers, QA specialists, GA & tool analysts, CRO strategists, and UX designers working in sync on your experimentation goals.
Typically a solo developer or a small, core-centric team with limited knowledge of A/B testing tools and methodologies, risking delays and subpar execution.
Service Scope
All-Inclusive, End-to-End – From ideation and technical setup to development, QA, and final deployment, we handle every stage for your A/B test campaigns and CRO projects.
Primarily Development-Focused – Lacks comprehensive A/B testing support and tool knowledge, limiting capabilities for big experimentation or complex test implementations.
Cost-Effectiveness
Transparent, Hourly Model – Pay only for the services you need, with no hidden costs. Gain a complete, cross-functional team—no need for multiple separate hires.
Hidden Costs for Each Stage – Separate fees for project management, QA, analytics, etc., quickly driving up expenses as your testing and development needs grow.
Flexibility & Integration
Seamless Collaboration – Our specialists coordinate under one process, ensuring timely delivery and frictionless integration with your internal workflows and marketing tools.
Limited Team Interaction – Focused on narrow deliverables with minimal synergy, often causing communication gaps, missed deadlines, or suboptimal test designs.
End-to-End Support
Dedicated Lifecycle Assistance – From platform migrations (Shopify, WordPress) to new site launches, we provide ongoing support for everything from setting up goals to troubleshooting post-launch issues.
Minimal Post-Launch Backup – Tends to offer limited dev support for diagnosing goal-tracking problems or resolving analytics bugs after deployment.
