https://chat.whatsapp.com/FDycCG1Qqe4ICrrW55cMK7?mode=hqrt1 Attendance confirmation Participation is confirmed in two steps: by registering for the event on Meetup and confirming again via WhatsApp on the day of the session. This coworking gathering is meant to create a relaxed space where people can work, exchange ideas, and connect with others in a friendly atmosphere. We do not aim for large or crowded events, but for a comfortable environment. If there are not enough confirmations during the day of the event, the session may be rescheduled. We invite you to share a weekly afternoon of work in Recoleta, in a comfortable and quiet coworking space, from 3:00 to 6:00 pm. This coworking meetup is designed for remote professionals, independent workers, digital nomads, researchers, writers, freelancers, and creatives who usually work online from their laptops. Just bring your laptop or work materials. The proposal is to work together, with each person focused on their own tasks, while sharing a calm and respectful environment. This is primarily a coworking space, with openness to social interaction, shared breaks, or simply getting to know new people, making new friends, or professional contacts. The venue has a café, spacious coworking areas, and lounge areas. You may also join the WhatsApp group, where we will share some social activities starting in January, for those interested in activities outside the coworking space and schedule. Location: Work Café Recoleta – Av. Santa Fe 1634, CABA Please confirm your attendance via Meetup before each meeting. Practical note: Some large tables have built-in power outlets with limited space. We recommend bringing USB cables or adapters. There are also wall outlets available. ------------------------- Te invitamos a compartir una tarde semanal de trabajo en Recoleta, en un espacio de coworking cómodo y tranquilo, de 15:00 a 18:00 hs, con tu computadora o materiales de trabajo.

**CONNECT. INSPIRE. TRAVEL. REPEAT.** **LOOP NIGHT 🌍** You know that feeling — you show up to an event, there are people **everywhere**, and somehow you still feel **alone**. You stand around waiting for someone else to make the first move. Nobody does. You go home with the same number of friends you came with. Loop Night is **built differently.** Small group. Real venue. A format that actually gets people talking — even if you're both introverts. *** **🧠 First — the Quiz** You'll be split into teams with strangers. Ten minutes in, you're already arguing about which country has the best street food or who invented the light bulb. Ice broken. Introductions handled! **🎤 Then — the Story Spotlight** Anyone who wants can share a travel story in a short presentation format. There are no boring adventures — only wrong angles. We've had someone break down their trip to China, someone rank Buenos Aires empanadas by neighborhood. Both got a standing ovation. Every talk turns into a conversation — questions, debates, personal stories from the audience. That's where the real connections happen. **This** edition is **open topic** — any adventure, any angle, any format.

Or feel free to make your own! If the link doesn't work, just message us and we'll send it directly. *** **Who is this for?** For people who want to find their kind of crowd — not just be around people 🤝 For those who collect experiences, not just destinations 🗺️ For anyone who wants to practice speaking in front of others and actually enjoy it 🎯 For travelers who want to leave with real tips from people who've already been there 💡 *** *After the main program — for those who want to stay — we pass mate around the circle. Argentine style. No rush. 🧉* *** **🕹️ Want in?** Spots are limited — and that's the whole point. A small room means everyone actually meets everyone. To join: send us a message to claim your spot. Once you're confirmed, entry is **ARS 12.000** cash at the door — or you can pay online via [the link](https://luma.com/fw3m945w). If it's not working, drop us a message and we'll sort it out. No drop-ins. Not because we're gatekeeping — because the atmosphere only works when the room is right. *** *Travelers Loop isn't a networking event.* *It's a room full of people who move through the world a little differently.* *If that sounds like you — you already know what to do.* 🌍 **CONNECT. INSPIRE. TRAVEL. REPEAT.**

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.
