what i build

Workflows, shipped end-to-end

Inbound qualification → CRM

how it works

Three ways to start

Audit

€4,900/ 2 weeks

Map your highest-leverage automations. Walk away with a prioritized backlog.

  • Stack + data audit
  • Top 5 workflows scored by ROI
  • Build estimates per workflow
  • 60-min walkthrough call

Build

€9.9–18kfixed scope

Pick a workflow from the audit. I ship it to production in 2–4 weeks.

  • Fixed scope, fixed price
  • Production deploy on your infra
  • Monitoring + rollback included
  • Loom handover + README

Retainer

€2.5–3k/ month, 12mo min

Ongoing maintenance, tuning, and new builds. 60-day payback guarantee.

  • Up to 2 workflows under maintenance
  • 1 new build per quarter
  • Weekly office hour
  • 4h response SLA

the stack

Boring, EU-hosted, all yours

n8n
Self-hosted workflow engine. You own every node, EU-resident, no per-seat tax.
Claude Code
The agent and the coding tool. Same model writes the workflow that runs the workflow.
Python
For nodes n8n can't express. Boring, debuggable, deployable anywhere.
Postgres / Supabase
State, logs, embeddings. Hetzner-friendly, EU regions, pgvector built in.
Langfuse
Trace every LLM call. Costs, latencies, prompts, outputs. Self-hosted.
Hetzner + nginx
€5–20/month per project. EU data residency, predictable bill.

faq

Questions worth asking up front

How is pricing structured?
Three tiers. Audit Sprint: €4,900, two weeks, fixed scope. Build: €9,900–18,000, fixed scope, fixed deadline. Retainer: €2,500–3,000/month, 12-month minimum, capped scope.
Who owns the IP?
You do. All workflows, code, prompts, and infrastructure are yours from day one. Repo lives in your GitHub org. No vendor lock-in clauses, ever.
Where does the data live?
EU-resident by default. Hetzner Nuremberg or Helsinki, Supabase EU regions, Anthropic EU endpoint where available. DPA on request. No data leaves the EU without your explicit approval.
What does the refund policy look like?
Retainer: 60-day payback guarantee - if measurable workflow value (time saved, revenue captured, cost cut) doesn't cover the retainer fee within 60 days, the retainer is free until it does. Audit: refundable for the first 3 working days, no questions.
What do I own after the engagement?
Source for every workflow, deployment scripts, n8n instance, database, secrets. A README explaining how each piece works. A Loom walkthrough for non-engineers on your team.
What happens if a workflow breaks at 3am?
Retainer clients get an on-call window with a 4-hour response SLA during EU business hours. Outside hours, alerts route to your team. Every workflow ships with health checks and a documented rollback procedure.
What does onboarding look like?
Week 1: read-only access to systems, audit doc shipped. Week 2: prioritized backlog and a working prototype of the top item. Week 3: production deploy. You'll have artifacts in your hands by day 5.
What's in scope for the retainer?
Up to 2 active workflows under maintenance, 1 new build per quarter (≤40h of work), monitoring, prompt tuning, model upgrades, weekly office hour. Out of scope: full-team training, building a separate product, anything that would need a second engineer.
