Classes every Monday, Wednesday and Friday from 19:00 to 21:00. **!!SIGN UP HERE**: [Katori Shinto-ryū Berlin Sign-up (google.com)](https://docs.google.com/forms/d/e/1FAIpQLSeBt4A13VgnEcgQQ2PDaruthmYMRWineG4KtUCKsuC9KBsCUQ/viewform) Registration is required before your participation so that we can prepare enough training equipment. **Address**: Belziger Str. 25, 10823 Berlin. **No previous experience required!** The classes are in English and German. **Our website**: [Kenjutsu Berlin - Official school of Katori Shinto-ryu in Berlin (katoriberlin.org)](https://katoriberlin.org/) **Katori Shintō-ryū** is one of the oldest Japanese sword fighting traditions (koryū) still practised today and is recognized by the Japanese government as a cultural intangeable asset. The school was founded in the middle of the 15th century by Iizasa Chōisai Ienao at the Katori Shrine (Katori jingū) and has become the origin of numerous other martial arts schools over the course of its almost 600-year history. The training consists of the continuous repetition of fixed sequences of movements (kata) and includes the use of classic Japanese weapons such as the sword (iai-jutsu, battō-jutsu, ken-jutsu, ryōtō-jutsu, kodachi-jutsu), the long staff (bō-jutsu), the lance (naginata-jutsu) and the spear (sō-jutsu), as well as unarmed disciplines, tactics and spiritual aspects. **The Katori Berlin dojo** is the only official shibu of Otake Nobutoshi-shihan’s dojo Shinbukan in Germany and fully dedicated to the transmission and study of one martial tradition: Tenshinshō-den Katori Shintō-ryū. Through these efforts we aim to contribute to the cultural preservation of this martial tradition. The dojo has one officially appointed shidosha. **Our sensei**: Sebastian Graetz has been active in martial arts since 1997. After almost 15 years of taekwondo in Berlin, he started with Katori Shintō-ryū in Asia in 2014. Since then, he has studied in Japan with Ōtake Risuke-shihan and Ōtake Nobutoshi-shihan, and in Vietnam with Malte Stokhof-shihandai. In 2023, he received his Menkyo license and permission to set up a training group in Berlin the following year.

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.

**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.

**Connected Westerville Night of Networking** *April Edition: The Introduction Economy* You've been to the networking events. You've done the small talk. Collected the cards. Forgotten the names. And walked out feeling like you just wasted two hours of your life. The problem isn't you. It's the format. Most networking events put you in a room and tell you to figure it out. So everyone defaults to elevator pitches and business talk, and nothing real gets built. Here's the truth about networking that most people miss: Your network isn't just who you know. It's who thinks of you when they're talking to someone else. *That's* The Introduction Economy. And it only works when relationships are real. There's a reason people who come once keep coming back. It starts with seven minutes that feel nothing like networking. Then we open it up. Free networking. More conversations. More momentum. This is a room full of corporate professionals, entrepreneurs, business owners, creatives, and career builders in the Westerville and Columbus area. The mix is the magic. You might never do business with everyone you meet tonight. But someone in this room will think of *you.* **By name**. So, the next time someone needs exactly what you do, you get the recommendation. **April 14th. RSVP now.** **When:** Tuesday\, April 14th \| 6:15 PM \-\- 8:00 PM **Where:** Vineyard Community Center \| 6000 Cooper Rd\, Westerville\, OH 43081

Whether you’re an engineer, builder, or just curious about how modern AI systems work, you’re welcome to join. No slides, no fluff — just real conversation about real systems.
