An AI engineering house.
Inspired in Silicon Valley. Incorporated in Estonia. Engineered in Germany.
MangoSeed.AI builds custom, sovereign AI — and is the engine room behind many brands and products. We build, others market under their own brand.
Three places, one standard.
Inspired in Silicon Valley
The ambition and pace of the Valley — products that actually change something, not slide decks.
Incorporated in Estonia
MangoSeed.AI OÜ, Tallinn — digital-first, EU-sovereign, lean.
Engineered in Germany
Built with German rigour: GDPR-native, auditable, on-premise-capable.
What we stand for.
Builders, not consultants
We don’t talk about AI — we build it. From the first look at your data to deployment.
Sovereignty first
On-premise or EU cloud, offline-capable, no data leakage. Your data stays your data.
White-label
We build the AI, you market it under your brand. That’s how all our brands come to be.
Alexander Holtermann
AI strategist and the mind behind Professor Digital. The MangoSeed brands grew out of his work — from the N.terion compliance software through Balzac Publishers to AI University. holtermann.io
