Azathoth opętał nasz spejs - dziwne koszmary, przerywające Wi-Fi i te sprawy. Teraz musimy tworzyć melodie chwalące tego przedwiecznego boga, by nie oszaleć (co najmniej nie bardziej niż zwykle). Spotkanie dla wszystkich zainteresowanych muzyką i tworzeniem muzyki, szczególnie trakerowej. Przewidziane jest wymienianie się wiedzą i doświadczeniami oraz wspólne/indywidualne eksperymenty. Nie jest wymagana żadna wiedza z zakresu muzyki - organizatorzy też nic nie wiedzą. Przynieście własne laptopy lub nie.

**ProductTank NoVA is back!** After a brief hiatus, we are relaunching the chapter with a format that cuts out the fluff and gets straight to the reality of building. Every product feed is flooded with AI hype right now, but what does it actually look like on the ground? Instead of a polished keynote, we are hosting **0 to 1 with AI: Real Product Talks**—a "Show & Tell" featuring 3–4 lightning talks focused on the intersection of AI and product. The framing for the talks is simple: *"Here is what I'm building, and here is what I'm stuck on."* We want to look at the messy, 0-to-1 reality of integrating AI into your workflows and products. *(Want to share what you are working on? Reach out! The bar is low-pressure, just 10–12 minutes to talk about a real AI problem you are trying to solve.)* **Agenda:** * **5:30 PM - 6:00 PM:** Doors open, networking, & name tags * **6:00 PM - 6:10 PM:** Welcome + Chapter Relaunch Intro * **6:10 PM - 7:30 PM:** Lightning Talks (Three 12-min talks + 5 mins Q&A each, with a 5-min stretch break) * **7:30 PM - 8:00 PM:** Open networking * **8:00 PM:** Soft close **Location & Logistics:** Herndon Fortnightly Library (Extended Hours Meeting Room) 768 Center St, Herndon, VA 20170 * **Parking:** We'll meet at the library, located just behind the Herndon Municipal Center. There is plenty of free public parking available around the municipal center. * **Metro & Bus:** Take the Silver Line to Herndon Metro Station, then connect via Fairfax Connector Route 921 or 950 to Historic Downtown Herndon. * **Driving (via VA-267/Dulles Toll Rd):** Take Exit 10 North (Centreville Rd, which becomes Elden St). Turn left onto Station St or Lynn St. * **Driving (via VA-286/Fairfax Co Pkwy):** Take the Elden St West exit. Turn right onto Lynn St. Looking forward to seeing everyone again and getting back to building!

Healthcare organizations are increasingly using cloud-based real-world evidence (RWE) platforms to power clinical research, population health analytics, and AI-driven insights. However, building these systems on AWS introduces complex governance challenges around privacy, compliance, and multi-institution collaboration. This session explores how to architect data governance into healthcare analytics platforms on AWS, focusing on practical design patterns rather than policy theory. We examine how ethical data stewardship principles such as consent, accountability, and responsible data use, can be implemented using cloud-native controls and services. The presentation walks through key architectural considerations for secure RWE platforms on AWS, including role-based access control, auditability, data minimization, and encryption, and how these capabilities support compliance requirements such as HIPAA and GDPR. Attendees will learn how federated, multi-account AWS architectures enable collaboration across institutions while preserving local data ownership and control. We will also discuss privacy-preserving analytics patterns on AWS, including approaches that support federated learning, differential privacy, and secure computation to enable AI-driven insights without exposing raw patient data. Practical implementation trade-offs such as performance, scalability, and operational complexity will be highlighted using real-world platform scenarios. Attendees will leave with actionable AWS architecture patterns and governance strategies for building secure, compliant, and scalable real-world evidence platforms that unlock innovation while maintaining patient trust.

## **1 Million Cups Loudoun – Business Presentation** **Featuring James Norris, Founder of Squeegee Samurai** **Wednesday\, May 13 \| 9:00 AM – 10:00 AM** **Venture X Loudoun** Join us as we welcome **James Norris**, founder of **Squeegee Samurai**, to the 1 Million Cups Loudoun stage for a conversation on building a service-based business from the ground up. *** ## **About the Presenter** James Norris transitioned from a career in **cybersecurity compliance** into entrepreneurship, taking a hands-on approach to building a business from scratch. Initially exploring the acquisition of an existing company, he ultimately chose to **build his own window cleaning business** after recognizing the simplicity, consistency, and opportunity within the industry. His journey reflects a growing trend of entrepreneurs moving from corporate roles into tangible, service-based businesses with clear demand and scalable potential. *** ## **About the Business** Squeegee Samurai provides **professional window cleaning services for residential and commercial clients**, delivering immediate, visible results — what James calls *“clarity through pane.”* In an industry where the fundamentals haven’t changed, Squeegee Samurai focuses on **high-quality, traditional techniques** paired with strong customer experience and operational discipline. As a solo operator, James currently manages every aspect of the business — from marketing and pricing to service delivery, quality control, and operations — while laying the groundwork for future growth. *** ## **Who James Is Looking to Hear From** James would especially value feedback from: * Business owners who have scaled service-based businesses * Operators of route-based or recurring revenue businesses * Entrepreneurs who have transitioned from corporate roles to hands-on work * Founders who have built teams from a solo operation * Anyone with experience in pricing, local marketing, or service scaling *** ## **Current Business Focus & Challenge** James is in the **early growth stage**, focused on building a foundation for scale through recurring storefront contracts and refining his pricing model. He is seeking feedback on: * Pricing strategy in a competitive, price-sensitive market * Whether to display pricing publicly or use promotional strategies * When and how to invest in advertising (where, how much, and when) * Timing and approach to hiring and team building * Balancing market penetration with long-term profitability This is a critical stage where the right decisions can significantly impact long-term growth and scalability. *** ## **Why Attend?** * Gain insight into building a service business from the ground up * Provide feedback on pricing, marketing, and scaling strategy * Connect with entrepreneurs navigating similar growth stages * Be part of a practical, real-world business conversation *** ## **About 1 Million Cups** 1 Million Cups is a national program that brings entrepreneurs and communities together to learn, connect, and grow through presentations and discussion. Loudoun’s chapter meets on the 2nd and 4th Wednesdays each month. Join us on **May 13** for coffee, connection, and a conversation around building, pricing, and scaling a service-based business. We look forward to seeing you there.
