The One Day Builder Retreat This is a single, focused day for builders, founders, and contributors to step away from the noise and regain clarity. It’s a chance to exchange real-world context, challenge ideas honestly, and spend time with people who understand what it actually means to build. Forget conference halls and forced networking. This day starts with intention and ends with real connection. The experience flows naturally across different environments. When your head needs space, the venue opens up with a quiet spot by the lake, a dip in the pool, or open areas designed for a real reset, not a rush. The retreat is family friendly. There are dedicated spaces for kids, including a playground, kids pool, and a small mini zoo, so you can stay present without leaving life behind. It’s a day to learn, connect, eat, drink, and dance, without sacrificing the depth, focus, or purpose that brought you here. Families and Kids Kids are welcome. Parents are responsible for supervising their children at all times. What We’re Going to Do The day moves in two connected waves, each feeding the next. Phase 1 · Builder Sessions We start with intention. A curated set of sharp talks and conversations, supported by our partners and sponsors, with a strong focus on the Starknet Foundation and its builder ecosystem, alongside real use cases from products already in production. We will cover crypto native payments, USDT flows, user onboarding, real world settlement, and how tools like Kast Card operate in everyday environments. The goal is simple: inject real context, not sell narratives. Expect discussions on scalability, Cairo, ZK design choices, real world constraints, what actually breaks when you ship, and how tools fit into real production stacks. Sessions are short, direct, and designed to trigger better questions, not fill slides. FounderHaus is a strong supporter of this event and is sponsoring a healthy space with cold plunge sessions and fresh fruits, creating an environment to reset, recharge, and stay sharp. The atmosphere stays open and alive all day. Food and drinks from start to finish, BBQ always on, soccer field open, plus pool and lake access. The space is designed for flow, not distraction. Bring your ID and check in with Kast Card on site for a chance to win $10 in prizes through Kast during the event. This is about signal, clarity, and shared context among builders who are actually shipping, using real products in real environments. Nothing is rushed. Nothing is passive. Phase 2 · The Shift As the sun moves, so does the energy. Music fades in. The DJs don’t chase the spotlight, they shape the rhythm of the day. The stage is present, but never intrusive, built to blend into the landscape, then disappear. As daylight shifts, immersive projections come alive across the surroundings. When the sun drops, laser shows cut through the dusk. Light and sound moving as one. Four DJs. One dedicated spot on the farm. A space designed for pure connection, high energy, and total immersion. From 14:30 to 22:00 non stop, the music does not break. No resets. Just a continuous journey. The pool and outdoor areas come alive around it all. Swim. Move. Relax. Let conversations unfold naturally around food, drinks, and rhythm. It is not just a lineup. It is a full day experience. If you stay, you’ll feel the difference. The Place We chose a place that allows people to stay all day. Open spaces, outdoor areas, and enough comfort to support long conversations without friction. We’ll have a pool with a waterslide, barbecue, a soccer field, a kids playground, a kids pool, open bar, a lake, mini-zoo and some DJs The place isn’t a backdrop. It’s part of how the retreat works.
