Report

I've been building (open source) communities since before it was a job title. Mambo, Joomla!, Magento, e-commerce optimization, enterprise SaaS. Communities often built on platforms they don't control, and when the platform changes the rules, years of trust and reputation just... disappear.

I studied psychology, which mostly taught me that we're usually really bad at predicting what people will do. So I got into experimentation, ran a CRO podcast for four years (200+ episodes), spoke at too many conferences, and ran Community & DevRel at Spryker until early 2026.

Barazo (ATproto-based forum) and Sifa came out of a frustration with Big Tech enshittification combined with a lifelong admiration for the open internet in general. And recently, ATproto in particular.

As a cognitive psychologist, I was mainly involved with behavioral analysis and conversion optimization: → Behavioral analysis: An effective client dialogue is based on the knowledge of the client.

Based on this information we analyzed and optimized the dialogue with the online customers of our clients. → Conversion optimization Based on insights from the client dialogue analysis we created and engaged in improvement trajectories. The effectiveness of improvements was always validated in a performance dashboard and through A/B/MvT testing in combination with (behavioral or profile) targeting.

Compute required Sample Size for your A/B tests (A-priori)

15 min

So if you want to get started with A/B testing, you should calculate up front if you have enough users and conversions to see if it is even possible to perform an A/B test on your site. There are some general rules of thumb out there that say "don't go A/B testing when you have < 1000 conversions", which is fine, but probably not really helpful in your situation. See http://www.gui.do/post/compute-required-sample-size-for-your-ab-tests for the full article and explainer video.
