**First meetup of the Columbus AI Engineering group.** We’ll kick things off with a practical, beginner-friendly discussion on: **How LLMs like ChatGPT actually work — and how to build real applications with them.** We’ll cover: * what’s actually happening under the hood (at a high level) * why LLMs behave the way they do (hallucinations, prompt sensitivity, etc.) * how people are building real systems with them today * where things break in practice This will be a **short, informal talk (\~15–20 min)** followed by open discussion and Q&A. 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. We’ll hang out afterward and get to know each other.

**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.

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy. In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia

**The idea for this group is to build a community where men can gather together and build connections & learn and grow from each other.** How we start each meeting is by each of us checking in with our "roses and thorns" aka what are the good things and the bad things going on in your life recently? Then we will go into a topic discussion. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **COMMUNITY AGREEMENTS** \*\*THERE WILL BE A ZERO TOLERANCE POLICY FOR NO-SHOWS. IF YOU RSVP TO A MEETING AND FAIL TO SHOW UP WITHOUT NOTICE, YOU'LL BE REMOVED FROM THE GROUP. THIS IS TO PRESERVE THE INTEGRITY OF THE GROUP\*\* 1. Confidentiality - EVERYTHING that is shared NEVER leaves this space so that this space remains safe and sacred. There is a zero tolerance policy for this. If a man is in violation of this, they will be permanently removed from the group. 2. Non-Judgement - we respect and honor every man’s truth so that we may receive the same from others. While we may not agree on everything, we commit to respecting every man’s perspectives and engaging in honorable discussion with one another. 3. Be committed - honor your commitment to this group and to yourself. If you attend a meeting, please commit yourself fully to the meeting. Also be committed to your own journey. When we fail, we own it & clean it up. 4. Speak from the heart - this is NOT a space to “look good”, have the “right” answers, and have it all together. Relax and know you are not alone. Be exactly who you are within the safety of this space. 5. Be supportive - This means always willing to provide encouragement to your fellow men, encourage action and momentum in each other’s lives.. Be willing to challenge each other. Be willing to hold each other accountable. 6. Participation - what you receive from this community will be a reflection of what you put into it. Period. We ask that you share your perspectives, reflect on others, and give/receive support when and where it’s needed.

[The Board Walks](http://www.theboardwalks.com/) are for curious people who love deep conversations. If that sounds like you, **bring a thoughtful topic** and join us for a 5-mile walk (10,000+ steps!). **HOW IT WORKS** **Step 1: Bring a topic** Before you arrive, think of **one** topic you want to explore. A question. A thought that's been on your mind. An obsession you want to geek out on. This is your ticket to the event. **Step 2: Circle up & share** We gather in a circle. Your friendly walk host gives a speech to set the tone. Everyone shares: your name, what you're grateful for, and your topic. That's it. 60 seconds. **Step 3: Walk, talk & float** We walk 5 miles. You naturally drift into conversation with 2-3 people at a time, pulled by topics that spark your curiosity. When you're ready to move on, just say: "I'm going to float!" **Step 4: Feel more alive** Two hours flies by. You're back where you started — but you feel different. More alive. More energized. More connected to yourself and others. That's why regulars join 20+ times. *For more details, read our [Orientation Guide.](https://www.theboardwalks.com/orientation)* **HOW TO BRING A GREAT TOPIC** A great topic = something you're genuinely curious about. Recent topics include: * "What are you passionate about right now?" * "What makes a good friend?" * "What's a belief you used to hold that you've completely changed?" * "How do you want to be remembered?" * "What would you do if money wasn't a factor?" Think of your topic like the dish you're bringing to our conversational potluck. If everyone brings an A+ dish (i.e. energizing, uplifting, expansive), we'll all walk away feeling lighter and brighter. **WHAT TO EXPECT** This isn't a fitness event with casual chitchat. It's a walking think tank where we explore life's big questions together, beyond small talk. *If you're looking for light banter or a standard networking event, this probably isn't the right fit.* But if you crave depth, genuine connection, and conversations that make you feel alive? You'll love it here. **FAQ** * Wear casual athletic attire and sneakers. It's a long walk! * We have multiple first-timers at each event. We work hard to create a welcoming, inclusive, clique-free space. * We welcome people of **all** ages, backgrounds, and industries who align with the [intention](https://www.theboardwalks.com/ground-rules) of this space. * Rain or shine, we've been out here nearly every week since July 2022. If the event is cancelled, we'll let you know. * Dogs, babies in strollers, parents, and friends are welcome — please text/email them the event link so they can RSVP and prepare a topic! **LOGISTICS** * If you'll arrive over 10 minutes late, we suggest skipping the event. It's hard to find us once we start walking, and your host can't answer messages during the event. * This walk is designed for everyone to *move together at the same steady pace* (about 20 min/mile). This format works best when the whole group moves in unison. If you have mobility limitations, we kindly encourage you to find an event better suited to your needs. * Read our [Orientation Guide](https://www.theboardwalks.com/orientation) for full details. * If you enjoy the event, send **[this](http://www.theboardwalks.com/)** to a friend or sign up for our **[newsletter](https://theboardwalks.beehiiv.com/)**. We're in multiple cities with more on the way. 🤠👋 **IF YOU WANT TO GO DEEPER...** [The Board](https://stan.store/ellebeecher/p/the-board) is the next step: a high-trust collective for renaissance people devoted to creating, connecting, and building lives that light us up. * This is a global HQ for people who crave big talk, deep connection, and dream collaborations with people across industries. If the walks feel like a spark... The Board is the fire. Apply [here](https://stan.store/ellebeecher/p/the-board).
