Wed, Oct 14, 4:00 PM### **Marketing & AI Leaders Afterwork — 2nd Edition** After our first **Japanese Cocktails Afterwork filled up**, we’re opening a second edition for those who couldn’t make it - and for a few new faces.

No panels. No formal agenda. Just an informal evening with an interesting group of people in a unique Japanese-inspired setting. **14 October · 18:00** **Near Sagrada Familia, Barcelona** Places are limited again. **Early bird registration is now open.**

Meet New People Interested in Psychology & Personal Growth
Wed, Sep 2, 4:00 PMWe want to start in the simplest and most human way possible: **meeting each other over a drink.** This first gathering will be an informal opportunity to discover the community, meet new people, exchange ideas and connect with others who share an interest in personal growth, psychology, philosophy, wellbeing and spirituality. But there’s another important reason behind this event. As Brilliant Minds Club in English grows, we want to collaborate with **psychologists, therapists, doctors, coaches, philosophers, educators, researchers, wellbeing professionals, spiritual practitioners and people from other fields with interesting knowledge and experiences to share.** In the coming months, we’d love to create **talks, workshops, discussions and other collaborative events** led by people within the community. So if you have an idea, a field you’re passionate about, a project you’d like to share, or simply feel that you could contribute something valuable, **we’d love to meet you.** And if you’re not a professional in any of these areas? You’re just as welcome. Come because you’re curious. Come to meet interesting people. Come to have a drink and a good conversation. Come to discover what Brilliant Minds Club is about. There will be no formal talk or workshop this time. **This first event is about people, ideas and connections.** Some of the best projects begin with a simple conversation. **Maybe this will be one of them.** Join us for the very first Brilliant Minds Club and become part of the community from the beginning. **Organisers:** **Alexander Perez:** social media strategist, entrepreneur and founder of [El Club de las Mentes Brillantes](https://www.meetup.com/club-mentes-brillantes/). **Edward Martin:** Journalist specialising in economics and finance, court-appointed expert, professional translator, English teacher and media contributor based in Barcelona. Free event with a mandatory drink purchase at the bar.

Why A/B Testing Sucks - Hatch Mixer Barcelona
Wed, Sep 16, 4:30 PM**UX Hub** is thrilled to welcome you to our next event: **Why A/B Testing Sucks** Most teams don’t have a problem with running experiments; they have a problem with how they interpret them. This talk shows how our industry’s obsession with p-values, “95% significance,” and single-number uplifts quietly leads to bad product decisions, misunderstood results, and wasted opportunities. Instead of yet another stats lecture, we’ll unpack how A/B tests and p-values can easily get misread in practice and why classical significance testing is so hard to explain to stakeholders. Then, we’ll explore a more intuitive way to talk about experiments: in terms of the probability of uplift, minimum expected impact, and business value, not arbitrary thresholds. You’ll walk away with practical guidance and report patterns you can use tomorrow. So that your A/B tests stop “sucking” and start supporting clearer, more honest decisions in your product team. **Speaker** Dr.-Ing. Maximilian Speicher is Director of Product Design at BESTSECRET. His (research) interests lie primarily with novel ways to do UX research and design, responsible and sustainable design, and beyond-screen and physical–digital interaction. He is also a freelance UX and product consultant, plays ringtennis, and blogs at maxspeicher.com/newsletter. **Hosts** This event is hosted by UX Hub BCN in partnership with Hatch Conference **Location:** Wallapop HQ **To join us, just:** ✅ RSVP here on Meetup ✅ RSVP here on Hatch conference - https://mixers.hatchconference.com/e/barcelona-uxhub ✅ Answer [this form](https://48db4b2d.sibforms.com/serve/MUIFALfB0bn_p1G9zS7yYICl8fr4aT-cjBYl7Ow1DKvi6gv1FzDSE3Dt9fmIH5k78PONlJNEn2S6UnpOuo_VNIeUd69dkI5RJ0kaw7TjtxPjtwYy8KKc80BkMTozTqyRXiKCcXK9G8y-NccOB4S1Ci0SPkuWLJ5BCVWC80yGZ9bhinpCpoBKNV5cyovr3wH4BWM1_lNTf8IsVTvO) **Details:** 🗓️ Date: Wednesday, September 16, 2026 ⏰ Time: 18:30 CET 📍 Location: Wallapop HQ **Why You’ll Love It:** Learn how to stop misinterpreting A/B tests and start making clearer, more confident product decisions with frameworks and reporting patterns you can use tomorrow. **Agenda:** 18:30\-19:00 \| Doors open 19:00–19:15 \| Introduction 19:15–18:55 \| Talk 18:55–19:15 \| Live Q&A **Educational partners:** [Interaction Design Foundation](https://ixdf.org/) [Uxcel](https://uxcel.com/?utm_medium=paid%20search&utm_source=google&utm_campaign=brand&utm_term=uxcel&utm_source=google&utm_medium=cpc&utm_campaign=23478421564&gad_source=1&gad_campaignid=23478421564&gbraid=0AAAAAoYVYnfrZ5Yt8YP5nzmg5PiQ4LvIK&gclid=CjwKCAjw6rfSBhAqEiwA_yocppX7EENM8-y2gWRMnWIprvZnHOrWMLhhAxQKPof1jyFAryWd1HY_ERoCJIQQAvD_BwE) **Sponsor:** [Uxia](https://www.uxia.app/) **P.S.** Please make sure to show up on time.
