Made in Europe · Hosted in Europe
Europe deserves its
own knowledge layer.
We’re European founders, tired of sending customer data across the Atlantic only to see it come back as someone else’s training data. Stacklink works the other way. Everything stays in Europe by default. No exceptions, no fine print.
Your data stays in Europe.
Hosted in Frankfurt, backed up in Amsterdam. Nothing reroutes through the US when traffic spikes. Ever.
Or run it on your own servers.
Install it on your own infrastructure, even fully offline. Your models, your keys, your rules.
GDPR, DSA and NIS2 — already sorted.
Compliance is finished before you sign. No last-minute DPA chase, no “we’re working on it” replies. Every action 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.
Where the time goes
A day a week, gone to searching.
McKinsey puts it at 19%. For 250 people, that’s roughly €3.3M a year lost finding things you already have. Stacklink takes on the six jobs that drain it — answers with sources, your permissions respected, you in charge.
Tap a tile to see one in action.
One question. Every system. A cited answer.
Stop hopping between four tabs to find the thing you already wrote down.
"How is churn trending?"
Real analysis on the real file — answered with a real chart.
Auditor asks. You hand over a signed zip.
AI Act evidence — one command, not a quarter of prep.
Ask the warehouse. Skip the queue.
"Where's `legacy_id`?" Every repo, one search.
Set the watch. Slack when it's green.

A few lines of code to search, ask, and manage your knowledge base.
// Initialize the Stacklink SDK
import { StacklinkClient } from "@stacklink/sdk"
const client = new StacklinkClient({
baseUrl: "https://app.stacklink.ai",
token: "sk_your_api_key"
})
// Search across all connected sources
const results = await client.search({
query: "How do we handle authentication?"
})
// Each result includes source attribution
console.log(results.results)
// [{ title, snippet, source, score }]
Stacklink SDK
Unified API to search, ask, and manage knowledge across all your connected sources.
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.
