AI-Powered A/B Test Significance Calculator with Experiment Design
Most SaaS teams run A/B tests incorrectly, peeking at results too early, running tests too short, or using wrong sample sizes. An AI experiment design tool that recommends sample sizes, monitors tests for validity, and provides statistically rigorous conclusions would prevent the expensive mistakes from bad experimentation.
Problem Statement
Growth teams run A/B tests using tools like Optimizely or VWO but make systematic statistical errors. They peek at results daily and stop tests when they see 'significant' results — often after just a few hundred visitors. They do not calculate required sample sizes before starting. They run 10 variants simultaneously without adjusting for multiple comparisons. The result is false positives that lead to shipping changes that do not actually improve metrics.
The Idea
An A/B testing companion tool that designs experiments correctly (sample size, duration, power analysis), monitors running tests for peeking bias and validity threats, and provides statistically rigorous conclusions, preventing the costly decisions from poorly designed experiments.
Why Now
A/B testing tools are commoditized but experimental rigor has declined. Growth teams run more tests but make more statistical errors. Most teams peek at results daily, stop tests too early, and confuse correlation with causation. The cost of a false-positive A/B test result, shipping a feature that does not actually work, is months of misallocated engineering effort.

Privacy-First Website Analytics for EU Businesses Without Cookie Banners
EU businesses struggle with GDPR-compliant analytics. Google Analytics requires cookie consent banners that 40-60% of users decline. A privacy-first analytics tool that provides useful website insights without cookies, fingerprinting, or personal data collection would give EU businesses accurate traffic data without the consent banner friction.

Solo founders and micro-SaaS builders operate in an information vacuum, they do not know if their metrics are good or bad compared to peers. An anonymous benchmarking dashboard that aggregates opt-in revenue, churn, and growth metrics from micro-SaaS products would provide the context indie hackers need to make informed decisions.
