A startup from Uster, Switzerland that is founded by Naresh Shan.
Generic whiteboards like Miro and Mural give you an open canvas; they don't carry the methodology. LSP isn't freeform drawing โ it's a structured sequence where the rails are what make it work. BrickThink reproduces those rails honestly online, built by someone who ran these workshops for years rather than someone who read about them. It's free and open source, so there's nothing to extract from an audience that guards this method, and if the hosted instance ever disappeared, anyone could run their own copy from source.
It's a faithful digital reconstruction of LEGOยฎ SERIOUS PLAYยฎ, not a whiteboard with bricks on it. The method's fixed five-stage sequence is encoded as first-class product structure โ a facilitator-driven stage state machine, breakout rooms that auto-compose each participant's individual model into one shared view, and scenario templates tuned per stage. The constraint is the point, and that's what generic tools can't reproduce. It's also Apache 2.0, free forever, with no paid tier and no waiting list.
Certified LEGOยฎ SERIOUS PLAYยฎ facilitators running paid client workshops remotely, agile coaches running retrospectives and working agreements across distributed teams, and leadership, People, and L&D roles running strategy alignment and team-formation sessions. All of them already know the method and want a remote-native equivalent that doesn't feel like a compromise.
The founder, Naresh Shan, ran LSP workshops for years for design teams he managed, after first encountering the method at a bank โ where one workshop got a room of people who didn't like each other to agree on what they were building and what they'd sacrifice to ship it. As his teams grew and went remote after COVID, flying people in to build with physical bricks stopped being practical and stopped being funded. Since the LSP method is openly published under Creative Commons, there was no good reason it should stay locked to people who could share a physical room. He built the tool he wanted and couldn't buy.
Next.js 15 and React 19 on the frontend, a Konva-powered 2D canvas, Yjs CRDT for real-time collaboration, and Supabase for Postgres, auth, storage, and row-level security. AI session reports run through the Anthropic API. It's deployed on Railway with separate web and worker services.
