S6E7 - Ways to destroy an experimentation culture

In this episode, we dive into the realities of CRO (Conversion Rate Optimization) today — from AI anxiety to experimentation culture and how teams should actually be structured. We start with a surprisingly philosophical take on photography and overthinking, then quickly shift into what’s really happening in the CRO and AI space right now. We discuss: * Why AI might be making everything look the same * The growing fear (and noise) around AI in CRO * How to structure CRO teams: centralized vs hybrid vs embedded * Why experimentation still struggles with a “nice-to-have” perception * What actually builds a strong experimentation culture * How individual contributors can influence culture without authority * And how to position CRO as a true growth engine, not just testing If you work in growth, product, or experimentation, this is a candid look at what’s changing and what actually matters.

S6E6 - The Uncomfortable Truth About AI, ROI, and CRO Careers

In this episode, we answer real, unfiltered questions from the CRO and experimentation community. We dig into how far AI can realistically help with experimentation, why revenue metrics like ARPU are a nightmare for MDE calculations, how to handle sketchy interview “audits,” and why ROI conversations never seem to end.No hype. No magic bullets. Just honest perspectives from people actually doing the work.Topics include: * Where AI helps (and quietly breaks) CRO workflows * How to think about MDEs for continuous metrics like ARPU * Making time for research when you’re already drowning * When “auditing a site” crosses into spec work * Volume hiring for CRO roles * Escaping (or not) the endless ROI loop * Why some CRO agencies don’t have designers Drop your own questions in the comments or check the links below to submit anonymously.- Ask us a question here: https://docs.google.com/forms/d/e/1FAIpQLSd8P5yCsO5NB6WPe204k1WExhH1Bs8w6nZxPRRn-BiAGozpaQ/viewform- Visit Koalatative here: https://www.youtube.com/@koalatative⏱️ Chapters00:00 – Intro & warm-up04:34 – How far can AI actually help in delivering CRO?11:19 – How do experimentation experts estimate MDE for continuous metrics like ARPU?15:28 – How do you make the most of research time when there’s no time to do anything?19:29 – How do you handle being asked to audit a site as part of a CRO interview?24:20 – How do you approach CRO in volume recruitment?28:21 – How do you get out of the endless ROI loop with stakeholders (and stop saying “CRO”)?31:46 – Why do some CRO agencies not have designers on the team?33:47 – Outro & announcements#cro #experimentation #abtesting #aiincro #growth #productmanagement #conversionrateoptimization #experimentationculture #careerintech #experimentationnation This is a public episode.
