The Blockspäti is WebZero's flagship event format: a multi-day pop-up that transforms a Berlin venue into an immersive crypto culture hub. The name is a play on the iconic Berlin Späti — the corner shop open all hours that doubles as a neighbourhood gathering point. Each Blockspäti features a branded mini-mart storefront, workshop and panel spaces, chef-catered meals, open bar, and a basement dancefloor. The format is designed to attract Web3 builders, protocol teams, and Berlin crypto regulars in equal measure — turning a technical conference week into a lived cultural experience. At Berlin Blockchain Week 2025, the Blockspäti ran for the second consecutive year, this time powered by Polkadot. It operated at MENA, Skalitzer Str. 114, Kreuzberg for seven days, delivering 16 events across the full week. What Is WebZero? WebZero is a Berlin-based full-service Web3 events and developer relations agency founded in 2022. The company specialises in immersive, community-first activations for blockchain protocols, DeFi projects, and Web3 infrastructure teams. WebZero has hosted over 10,000 guests across 12+ activations, consistently outperforming industry benchmarks for attendance loyalty, show-up rate, and brand recall. The agency operates at the intersection of culture, technology, and community — producing events that feel like Berlin, not like a conference. Website: joinwebzero.com · @joinwebzero The Brief: Berlin Blockchain Week 2025 Berlin Blockchain Week is the largest independent Web3 gathering in Europe, taking place annually in September across venues in Mitte, Prenzlauer Berg, and Kreuzberg. It attracts thousands of developers, founders, investors, and protocol teams from across the world. The brief for the Blockspäti at BBW 2025 was clear: create a destination that Polkadot's ecosystem and the broader Web3 community would return to every single day. Not a conference booth. Not a side event. A genuine Berlin institution for one week only. Specific objectives: Deliver a minimum of 10 events covering workshops, afternoon programming, and evening raves Attract a high-quality audience: founders, developers, and ecosystem builders Generate organic social reach without paid promotion Demonstrate Polkadot's investment in Berlin's Web3 community Capture verified attendance and loyalty data via RFID wristband analytics What WebZero Delivered Venue and Set Design Full buyout of MENA, Kreuzberg for seven days. Custom Polkadot-branded set design across all three floors: crypto mini-mart storefront at the entrance, workshop and panel space on the ground floor, garden terrace for evening networking, and a basement dancefloor for nightly raves. Programming: 16 Events in 7 Days 16 distinct events ranging from technical developer workshops and ecosystem panels to networking dinners, quest stations, and closing raves. Programme co-designed with ecosystem partners and community contributors. Catering and Hospitality Private chef providing breakfast, lunch, and dinner across the full week. Open bar from noon through to closing each night. Attendees who might spend 30 minutes at a standard side event stayed for hours. Analytics and Attribution RFID wristband technology via the Polar analytics suite, deployed for the first time at BBW 2025. Every check-in tracked, attributed, and reported in a post-event KPI report. Social and Media Dedicated photographer and videographer producing content daily. Posts and reels published in real time from @joinwebzero. Luma pages promoted to 30,000+ Web3-native subscribers. Organic reach outperformed paid campaigns from competing activations.

Attendees made it their base and built their schedule around it — not the other way around. 2. Genuine Berlin Hospitality Private chef catering, open bar, and real club infrastructure signalled quality. Word spread organically. Queues formed nightly without a single paid ad. 3. Programming for Builders Technical workshops and ecosystem content ran alongside social programming. The result: 44% founders and developers in the audience — the exact demographic that drives protocol adoption. 4. Community Ownership Programming was co-designed with ecosystem community members. This created a sense of ownership that converted first-time visitors into advocates who promoted the venue to their networks. 5. Data-Driven Operations RFID analytics via Polar gave real-time attendance data across all 16 events, enabling mid-week programming adjustments and a verified post-event report for sponsors. What Attendees Said The Blockspäti earned a 4.8/5 rating on Luma across all 16 events at BBW 2025. "Best venue of the week" — cited in multiple independent reviews and social posts "Came for one event, stayed for three" — reflected in the 28% return rate "Felt like Berlin, not a conference" — the most commonly used phrase in qualitative feedback Organic reach on X outperformed all paid activations during the same week, without a single promoted post.

A fully managed crypto culture venue in Kreuzberg that drew queues around the block every night, without a single paid ad.

The Blockspati is WebZero's main event format. It takes a Berlin venue and turns it into a proper crypto culture hub for the duration of a conference week. The name comes from the Berlin Spati, the corner shop that stays open all hours and ends up being where everyone actually hangs out. Every Blockspati has the same bones: a branded mini-mart at the entrance, workshop and panel space, chef-catered food, an open bar, and a basement for the nights. The idea is to pull in Web3 builders, protocol teams, and the local Berlin crypto crowd at the same time, and make it feel like somewhere worth being rather than another side event to tick off. BBW 2025 was the second year running. This time it was powered by Polkadot, based at MENA on Skalitzer Strasse in Kreuzberg, and ran for seven full days across 16 events. Who Is WebZero? WebZero is a Web3 events and developer relations agency out of Berlin, started in 2022. The team builds activations for blockchain protocols, DeFi projects, and infrastructure teams that want something more than a booth at a conference. 10,000+ guests across 12+ activations so far. The focus has always been on making events that feel like they belong in Berlin, not events that happen to be held there. Website: joinwebzero.com · @joinwebzero The Brief Berlin Blockchain Week runs every September and is the biggest independent Web3 gathering in Europe. Developers, founders, investors, and protocol teams come in from all over. The ask for Blockspati at BBW 2025 was simple: build something people would come back to every day. Not a conference booth. Not a one-night side event. A place that became part of people's week. That meant: Running a full week of programming, from morning workshops through to late night raves Pulling in a quality audience: founders, developers, builders Getting organic reach without spending on ads Giving Polkadot a genuine presence in the Berlin Web3 community Tracking everything properly with verified attendance data What Got Built Venue and Set Design Full venue buyout at MENA, Kreuzberg for seven days. Three floors: a Polkadot-branded mini-mart storefront at street level, a ground floor for workshops and panels, a garden terrace for evenings, and a basement club for the nights. 16 Events Developer workshops, ecosystem panels, networking dinners, quest stations, and closing raves. The programme was built together with ecosystem partners and community contributors, not handed down to them. Food and Bar Private chef on site for breakfast, lunch, and dinner every day. Open bar from midday until close. People who would normally spend half an hour at a free drinks event ended up staying for four or five hours. That was the point. Data and Tracking First time WebZero used RFID wristbands at BBW, running through the Polar analytics platform. Every check-in logged and attributed. A full post-event KPI report went out to sponsors. Content Photographer and videographer on site every day. Daily posts and reels from @joinwebzero. The Luma pages went out to 30,000+ subscribers. No paid promotion. Organic reach still beat paid activations from other events that week. The Results All figures come from RFID data and Luma records. Attendance 912 unique attendees 1,266 total check-ins 4,444 total registrations 16 events delivered 186 peak check-ins at one event 4.8/5 Luma rating Return Visits 28% average show-up rate across all events 28% of attendees came back for at least two events (251 people) 6% came back for three or more (55 people) 2.2% attended four or more events (20 people) Broken down by visit frequency: 1 event: 661 guests, 72.5%, first visit 2 events: 176 guests, 19.3%, came back 3 events: 55 guests, 6%, regulars 4+ events: 20 guests, 2.2%, proper superfans More than a quarter of all unique attendees returned during the same week. That is not typical for a free side event. Who Was in the Room 494 attendees filled in a survey on their professional role after the event. Technical Founder: 17.8% Developer: 15.6% Business Development: 11.3% Founder: 10.7% Non-Technical Founder: 9.3% Marketing: 5.7% Product: 5.7% Other or not specified: 23.9% 44% were founders or developers. That is the audience protocols actually want to reach: people who build on things, adopt things, and tell their communities about them. Source: WebZero post-event survey, BBW 2025. n = 494. Why It Worked It ran all day, every day Most side events run for a few hours on one night. The Blockspati ran 10am to 2am for a week. People made it their base. They came for a workshop in the morning, came back for a panel in the afternoon, and then stayed for the rave. The format makes returning easy because there is always a reason to come back. The hospitality was real An open bar and a private chef in a proper venue is a different thing to a warm beer at a standing event. People noticed the difference and told their friends. That is where the queues came from. No ads needed. The programme was built for builders Technical workshops and developer content ran every day alongside the social stuff. A 44% founder and developer audience does not happen by accident. It happens because the programme gives those people a reason to be there. The community had a stake in it Ecosystem contributors helped shape the schedule. When people have input into something they become advocates for it. That is a big part of how organic reach ends up outperforming paid promotion. The data was actually tracked RFID wristbands meant real numbers. Not estimated footfall or guessed attendance, verified check-ins per event. That made the post-event report useful to sponsors and gave WebZero the data to make programming calls mid-week. What People Said 4.8/5 on Luma. A few things came up repeatedly in written feedback: "Best venue of the week" appeared in multiple independent posts and reviews "Came for one event, stayed for three" tracks directly with the 28% return rate in the data "Felt like Berlin, not a conference" was the most common phrase across qualitative responses Organic X reach that week was higher than paid activations running at the same time. No promoted posts were used. Frequently Asked Questions What is the Blockspati?
