w3.hub Berlin
w3.hub is a workspace provider in Berlin that serves founders and developers working on new technologies. Teams can rent coworking desks or private offices and use meeting rooms for their work with colleagues and partners. The hub combines this physical working environment with a technology community, giving members access to people beyond their own company.
w3.hub works with teams in AI and robotics as well as quantum technology and blockchain. Its community includes people developing services for digital assets or using AI in finance, alongside other technology businesses. Shared workspaces and professional exchange help founders discuss technical questions and explore collaboration with other teams.
Coworking and event spaces in Kreuzberg
w3.hub is a commercial workspace operator with an event business attached. w3.hub's own numbers are 2,500 square meters over five floors, 110 or more members it describes as founders, engineers and researchers, around 70 events a year, and a community network it puts at 15,000 people. The space it sells covers coworking desks, private offices for teams of four to twelve, meeting rooms bookable by the hour or the day, and two event lofts of 500 square meters each that take up to 250 standing guests or 100 seated.
The legal entity is w3.hub GmbH & Co. KG at the same Möckernstraße address, with Isabell Kruse as managing director and the register entry HRA 61930 B at the Amtsgericht Charlottenburg in Berlin. w3.hub names w3.group as its operator and describes that group as a frontier tech ecosystem in Germany made up of an investment arm, an infrastructure provider and a media house. w3.hub's structured data gives 2022 as the founding year, and an outside portrait by the Berlin studio Visionary describes it as a coworking space, event venue and investment hub for the web3 scene of the city.
Beside the desk business w3.hub sells ecosystem tours, which it offers to corporate, investor and university groups as insider-led visits to the founders and funds around it, from a two-hour format to a program over several days. Ledger and Jägermeister appear as its house partners.
The pivot: from Berlin's home of web3 to four frontier fields
w3.hub started as coworking and event space for web3 companies. Blockchain remained its main focus through spring 2026. w3.hub added AI to its program in June and expanded to robotics and quantum technology by July.
The premises grew from 1,500 square meters on three floors to 2,500 square meters on five floors. Alongside workspaces and event rooms, the hub developed support for founders building in these four fields.
The four topic verticals w3.hub names now
w3.hub now supports work in artificial intelligence, robotics, quantum technology and blockchain. Its AI program includes LLM hack nights and the AI Agents Summit, where Berlin's AI builders meet. The factory loft provides space for robotics demos, workshops and teams working on embodied AI. In quantum technology, w3.hub brings together Berlin's researchers and startups to turn research results into companies. The hub also hosts the Berlin Blockchain Festival for its onchain builders.
Blockchain remains part of w3.hub alongside the three additional fields. The hub retains its festival, its onchain builder focus and the w3 name. For finance professionals, these fields span work across AI and blockchain: risk teams document models, payment teams test instant settlement, and treasury desks examine tokenized funds.
w3.hub organizes AI events alongside its established program for onchain builders. Registrations run through a public Luma calendar for formats including ACT Berlin with AI Coworking Tuesday and Berlin Builder HQ sessions on building with AI. According to its newsletter, dated 24 July 2026, a Claude meetup used two full floors to double capacity after close to 1,000 sign-ups, with one floor for everyday use and another for agentic systems and code.
Events and services after the repositioning
w3.hub announced expanded founder support beyond workspace rental to revenue creation, go-to-market work and tooling. A preview for members and partners was scheduled for 28 August 2026, followed by a public launch on 1 September 2026. w3.hub describes the change as an expansion of its founder support, alongside a broader subject list.
The founder-support work uses the name Circuit. Both Circuit and w3.hub remain in use for the house at Möckernstraße 120.
On 30 October 2025, w3.hub announced a move toward community-led ownership after two and a half years, more than 30,000 visitors and more than 250 events. A conference on decentralized physical infrastructure networks was announced for 27 November 2025.
Berlin Blockchain Festival and the week around it
The Berlin Blockchain Festival takes place at w3.hub. Organizers reported more than 7,000 attendees and more than 140 events for the 2026 edition, across Summit, Hacker, Builder, Bitvavo and Community formats. The festival program covers DeFi, MiCAR insurance questions, institutional adoption, tokenized assets and payments.
The Berlin Alliance coordinates events during the same week, including the Solana Summit, DappCon, Web3 Summit and AI Agents Summit. The German Blockchain & AI Week also ran at w3.hub, with more than 60 speakers on subjects from decentralized and centralized exchanges to tokenization and taxes. These events are part of the wider blockchain in Berlin and web3 in Berlin communities.
What is w3.hub?
w3.hub is a workspace and event house at Möckernstraße 120 in Berlin Kreuzberg for people building in AI, robotics, quantum and blockchain. w3.hub rents coworking desks, private offices for teams of four to twelve and meeting rooms, and it runs two event lofts of 500 square meters each for up to 250 guests. w3.group operates the space through w3.hub GmbH & Co. KG.
Where is w3.hub in Berlin?
w3.hub is at Möckernstraße 120, 10963 Berlin, in Kreuzberg next to Gleisdreieck Park. The nearest stations it names are Möckernbrücke on the U1 and U7, Gleisdreieck on the U2 and U3, and Anhalter Bahnhof on the S1, S2, S25 and S26. The building is a listed factory from 1905, renovated in 2022, and w3.hub states step-free access throughout with no car parking on site.
Did w3.hub change its strategy?
Yes. In summer 2026 w3.hub expanded from web3 to AI, robotics and quantum technology. Blockchain remains part of its program. The hub also added founder support, publicly launched on 1 September 2026 under the name Circuit.
Who runs w3.hub?
w3.group operates w3.hub and has investment, infrastructure and media businesses in Germany. The operating company is w3.hub GmbH & Co. KG at Möckernstraße 120, with Isabell Kruse as managing director, registered at the Amtsgericht Charlottenburg under HRA 61930 B. Ledger and Jägermeister are listed as house partners.
Can you book w3.hub for an event?
Yes, and w3.hub opens its event space to members and outside clients alike. w3.hub offers two event lofts of 500 square meters each for conferences, hackathons, meetups, panels and private dinners, with a capacity it gives as up to 250 guests standing or 100 seated. Stage, sound, screens and streaming-ready equipment come with the room, and w3.hub names an in-house events team for planning and setup plus promotion to the people around the house. Requests go through its contact form, email or WhatsApp.
Is w3.hub the same as a Berlin web3 hub?
w3.hub is one house in Berlin, not the city's scene as a whole. w3.hub is the address people mean when they search for a web3 hub in Berlin, because it held that description itself until 2026 and still hosts the Berlin Blockchain Festival, but Berlin's blockchain and web3 work also runs through association offices, university groups and conferences with no single home. Bundesblock and the week of parallel conferences are on the blockchain in Berlin page, the builder and privacy side on web3 in Berlin. Munich has its own house of this kind in W3MUC, and Zurich has Trust Square.
w3.hub and Finance Loop
Finance Loop covers AI and blockchain in finance, subjects also discussed at w3.hub. Finance Loop members who follow the Berlin market find the city context on its web3 in Berlin and blockchain in Berlin pages, and the German Blockchain & AI Week at w3.hub in its event archive.
