Dear Book Enthusiasts, For our April gathering, we’ll be reading *Satantango* by the Hungarian writer **László Krasznahorkai**. First published in 1985, this haunting and hypnotic novel unfolds in a decaying Hungarian village after the fall of a collective farm. As rumors spread that the long-absent Irimiás has returned, the remaining residents are drawn into a slow-moving dance of hope, manipulation, despair, and illusion. *Satantango* explores the fragility of belief, the psychology of communities in decline, and the uneasy space between redemption and deception. 📅 Date & Time: 12.04.2026 at 15:00 📍 Location: Audrey coffee, Holzendorffstraße 18, 14057 Berlin 💬 Fee: As always, a 3 € contribution after the meeting helps cover organization costs I’m very much looking forward to discussing this darkly atmospheric and philosophically rich novel with you — and to sharing another thoughtful afternoon together. Warmly, Sofya

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers.
