Munich-based founder-owned lightweight team wiki (Nuclino GmbH, 2015), all-German hosting, SOC 2 Type II, 12,000+ teams incl. NASA, MIT.

In short

Nuclino, in the Docs & wikis category, offers EU hosting with Germany as its hosting location, but a US parent or sub-processor leaves material CLOUD Act exposure.

Assessment notes

Nuclino GmbH (Munich, Germany; founded 2015 by Björn Michelsen et al.) is a profitable, fully founder-owned lightweight team-knowledge-base (explicitly no venture capital, no PE, no parent) that hosts all customer data in Germany with SOC 2 Type II attestation and GDPR compliance. Customer base of 12,000+ teams including NASA, Ubisoft, MIT, Paddle, Vistaprint. Real-time collaborative editing, visual knowledge graph (the differentiator vs Notion), Sidekick AI assistant. Signals: EU-owned (German GmbH), EU-hosted (Germany) but material CLOUD Act exposure: primary hosting runs on AWS and Heroku (US hyperscalers) with FrontApp (US) for support, so customer documents sit with US-jurisdiction infrastructure providers; SOC 2 Type II certified, sub-processors publicly disclosed. Gap: no publicly accessible DPA. The privacy policy directs procurement buyers to contact@nuclino.com rather than offering a self-serve download.

OVERVIEW

About Nuclino

Nuclino is a Munich-headquartered lightweight team-knowledge-base operated by Nuclino GmbH and founded in 2015 by Björn Michelsen (CEO, co-founder), and one of the structurally cleanest listings in the docs-and-wikis category. The company is profitable, fully founder-owned, no venture capital and no private equity on the cap table, no parent conglomerate, and explicitly positions this independence as a customer benefit ("we focus on customers instead of pleasing investors or chasing another funding round"). The product is differentiated from Notion / Confluence / Coda by its lightweight design philosophy (speed and simplicity over feature bloat) and its visual knowledge graph view that lets teams see their documentation as a connected network rather than a folder tree.

For procurement-grade EU buyers Nuclino ticks every box on the rubric. The legal entity is Nuclino GmbH in Munich, Germany: German Handelsregister-registered, GDPR-aligned, with all customer data hosted in Germany. SOC 2 Type II attested. The customer base reaches 12,000+ teams across NASA, Ubisoft, MIT, Paddle, Psyon Games, Invoice Simple, Vistaprint, and many others: strong cross-sector enterprise reference set including US federal-civil + Hollywood AAA studio + university + B2B-SaaS adoption.

Pricing is freemium with paid Standard, Premium, and Enterprise tiers; specific entry-tier EUR figures were not captured at audit. The product line now includes the Sidekick AI assistant for AI-augmented note-taking and document workflows; Canvas as a new visual editor. Best fit: German and EU SMBs and mid-market teams wanting a Notion alternative with explicit German data residency, lightweight UX, and a knowledge-graph view; procurement-grade buyers prioritising bootstrapped + founder-owned + SOC 2-attested vendors over US-VC-funded competitors (Notion, Coda, Confluence). Together with HumHub (DE, AGPLv3) and BookStack (UK, MIT) Nuclino completes the directory's top-tier sovereignty trio for the docs-and-wikis category.
