Breaking The Echo Chamber
Breaking the Echo Chamber is a podcast series that exposes the uncomfortable truths about why most experimentation programs fail to drive real business impact. Host Manuel Da Costa, founder of Efestra, challenges industry orthodoxies and tackles the systemic issues that trap teams in endless testing cycles without meaningful results. Each episode reveals how common practices like tool proliferation, process obsession, and tactical thinking create a dangerous disconnect between test results and strategic decisions. If you're tired of running experiments that executives don't trust or implementing tests that never see the light of day, this series cuts through the industry noise to show you what's really broken and how to fix it. Perfect for experimentation practitioners, product leaders, and executives who suspect their testing programs are generating more activity than actual business value.
