More than coworking. It’s a source of innovation (and good projects)
Effect? At 54 Koszykowa Street (a stone’s throw from the Warsaw University of Technology), the first dedicated hub for Web3 and AI in Poland was born. There are over 70 workstations for everyday work and an event space that can gather up to 100 knowledge-hungry builders.
Where does the heart of the Polish blockchain and Web3 beat?
If you think that K3 is only comfortable chairs and fast Internet, we need to disabuse you. It is a place driven by community and industry events.
This is where meetups like this take place Warsaw Meetup: Advanced Edition3-day coding marathons at the intersection of cryptocurrencies and artificial intelligence (ETHWarsaw Spring Hack), or events in the series that are extremely important from the adoption point of view ETHLegal – supported, among others, by the Ministry of Finance.
April 2026 full of events. What’s happening in K3?
Kolektyw3 is a living organism, and the spring calendar for 2026 only confirms this. The place is buzzing and the coming weeks are absolutely buzzing must-be for anyone building in Web3. In April alone, the following events are planned at Koszykowa:
- April 1: Vibecoder Wednesday – a looser networking format for the local ecosystem.
- April 8: WarsawJS Meetup – met by the Warsaw JavaScript community.
- April 9: Cowork with ETHGlobal in Warsaw – a unique opportunity to work side by side with representatives of the global ETH community and establish international contacts.
- April 11: ETHWarsaw Bootcamp – a huge dose of practical knowledge. An ideal place for Web2 developers who want to learn about blockchain and build their first dApp with AI support.
- April 14: K3 Sessions: To Err is AI – conversations about how (not) to work with AI.
Enter the game. Packages for airdrop hunter and pro-builder
By joining Kolektyw3, you do not pay for the desk. You are paying for an entry ticket to a network of contacts that would otherwise take months of tedious networking at foreign conferences. Here, at the coffee machine, you can meet a lawyer who will tell you whether your token complies with the MiCA directive, or a dev who will find a loophole in your smart contract.
K3 offers very marketable and flexible packages:
- Daily Pass (PLN 69/day): Just the right time to drop by, feel the atmosphere of K3, work with the hot desk and stay for the evening meetup.
- Viber (PLN 399/month): Option for regulars. Unlimited hot desk, discounts on workshops and bootcamps, and discounts on educational workshops.
- Hacker (PLN 1,199/month): “God mode” for real builders. A dedicated desk, with 24/7 access (because the best ideas are born during nightly commits), priority in mentoring programs and the ability to organize your own meetings in the hub.
It’s time to go out to the people!
The Web3 industry in Poland has long ceased to be the digital Wild West. It is dynamically professionalizing, attracting capital and becoming increasingly integrated with the AI revolution. Kolektyw3 is the best proof that the Polish ecosystem is mature enough to have its own physical “embassy”.
