Run statistically rigorous A/B tests that validate ideas, eliminate guesswork, and compound into measurable revenue growth.
A/B testing is the engine of conversion optimization — but most teams run tests wrong. Bad hypotheses, insufficient sample sizes, premature test calls, and inconclusive results waste time and erode trust in experimentation. We bring statistical rigor, structured hypothesis processes, and disciplined analysis to every experiment.

These are the cro challenges we solve every day for businesses like yours.
Without data-driven hypotheses, you're testing HiPPO ideas — wasting cycles on low-probability experiments.
Declaring winners before reaching statistical significance produces false positives that waste development resources.
Tests without clear hypotheses, predictions, and success criteria can't produce actionable learnings — win or lose.
Running tests on low-traffic pages without proper sample size planning means experiments never reach significance.
Test variations have rendering bugs, load slower than control, or break on certain devices — biasing results.
Test results aren't documented or shared — teams repeat failed experiments and don't build on successful patterns.

A comprehensive approach that covers every aspect of cro.
Build data-driven hypotheses from analytics, heatmaps, and user research — not opinions or best practice lists.

Build pixel-perfect test variations with cross-device QA — ensuring clean experiments that don't bias results.
Rigorous analysis using appropriate statistical methods — frequentist or Bayesian depending on your testing platform.
Every test gets documented with hypothesis, results, learnings, and implications — building organizational knowledge.
Maintain 4-8 concurrent experiments with proper traffic allocation and test scheduling.
Analyze analytics, heatmaps, and recordings to identify the highest-probability optimization opportunities.
Write structured hypotheses: 'Because [data], we believe [change] will [effect], measured by [metric].'
Calculate sample size, plan duration, design variations, and write QA specifications.
Build variations, test across devices/browsers, and verify tracking before launching.
Monitor test health, wait for significance, and analyze results with proper statistical methods.
Document learnings, implement winners, and feed insights into the next hypothesis cycle.
Detailed results for each test with statistical analysis, screenshots, and implementation specs.
Prioritized queue of 20+ experiment ideas with data sources and expected impact.
