What Stacklink is

Stacklink is the company brain for European companies. It connects every tool, indexes every document, message, and code change, and serves one permissioned agent.

Humans and agents pull from the same knowledge. Sovereign, cited, audited. Wherever work happens.

Europe deserves its own knowledge layer.

EU-resident by construction. Sovereign on your servers when you need it. No transatlantic round-trips, no surprises.

01

EU-resident by default.

Frankfurt primary, Amsterdam backup. No US failover, no fine print — data never leaves the continent.

02

Self-host when you need to.

Run the whole stack on your own infrastructure, fully offline if you want. Your models, your keys, your rules.

03

GDPR, DSA, NIS2 — shipped.

Compliance is finished before you sign. DPA ready on day one, every action signed and logged.

Founded in the Netherlands, built with friends across the continent — Berlin to Helsinki, Lisbon to Tallinn. Europe doesn’t need permission to build its own AI.

Pilot the brain that cites every answer.

Cloud customers run on Vercel + Supabase EU regions only, with an app-layer EU allowlist that blocks any non-EU LLM provider. Sovereign customers can self-host the entire stack (Helm chart or Docker Compose) — air-gapped clean, no telemetry leaves the cluster. Audit hashes are written per turn so every action is verifiable.

Google Drive, Notion, GitHub, Slack, and Postgres (ingest plus live read-only SQL), with Gmail (read-only) shipping in beta. New connectors ship behind the same publisher contract — adding one is a config change, not a fork. Coming next: OneDrive, Confluence, Linear, BigQuery, Outlook.

Every answer is grounded in your indexed sources via Anthropic-style contextual retrieval + BGE reranker. Citations are mandatory in the output schema — if the retriever returns nothing relevant, the agent says so rather than hallucinating. You can verify every claim by clicking the chip.

Sovereign is the self-host tier — Helm chart, air-gappable, customer-owned keys, customer-owned models (Pharia, vLLM, TGI, Ollama, Bedrock EU, Azure EU). Pick Sovereign when contractual or regulatory commitments require extraterritorial-law immunity, on-prem residency, or zero telemetry egress. Otherwise Pilot/Core on Stacklink Cloud is faster to start.

Pilot: under 30 minutes — connect Google Drive, Notion, or GitHub, pick a workspace, start asking. Sovereign: about a day for the Helm install + first source ingest, including the cluster provisioning. Indexing scales with corpus size; you can query the moment the first document lands.
