AI Assistants
01Custom copilots trained on your data — answering, drafting and routing inside Slack, your inbox or your app. Fewer tabs, faster replies.
- RAG over your docs
- Slack / email native
- Guardrailed + auditable
Systems online
Automation that
runs itself.
We build AI assistants, agents and workflow systems that take the repetitive work off your team — connected to the tools you already use, running quietly in the background.
Built on the stack you already run
What we build
Four ways we take work off your team.
Autonomous Agents
02Multi-step agents that decide and act: qualify leads, reconcile data, chase follow-ups, update your CRM — end to end, with a human in the loop where it counts.
- Tool-using workflows
- Human-in-the-loop
- Full run logs
Workflow Automation
03The plumbing between your tools. We connect systems that don't talk to each other and remove the copy-paste steps that eat your week.
- n8n / Make / API
- CRM & data sync
- Zero-touch pipelines
Custom Internal Tools
04When off-the-shelf won't fit, we build the dashboard, portal or back-office app around your process — and wire the automation straight into it.
- Next.js + serverless
- Ships in weeks
- You own the code
How it works
Three steps. Working software every week.
01
Map
We audit your workflows and find where hours leak. You get a prioritized automation map — highest ROI first.
02
Build
We design, build and connect the system in short cycles. You see working automation every week, not a black box.
03
Ship & tune
We deploy, monitor and calibrate against real usage. Automation that drifts gets fixed — it stays reliable.
What it's worth

Who we are
A build partner, not a black box.
FlowStack Systems is an AI automation studio. We embed with founders and operators to remove the manual work that scales with headcount — and replace it with systems that don't.
We stay close to the code and close to your team: every system we ship is documented, monitored and yours to keep. No lock-in, no mystery.
- Founder-led delivery
- Own your code & data
- European, remote-first
Questions
The things people ask first.
How fast can you ship?+
First working automation is usually live within 2–4 weeks. We work in weekly cycles so you see progress continuously rather than waiting for a big-bang delivery.
Do we own what you build?+
Yes. Code, workflows and credentials are yours. We hand over documentation and can train your team, so you're never dependent on us to keep running.
Which tools do you work with?+
OpenAI and Claude for models; n8n, Make and direct APIs for orchestration; Airtable, Supabase, HubSpot, Slack and most SaaS you already run. If it has an API, we can wire it.
How do you price?+
Fixed-scope projects for defined builds, or a monthly retainer for ongoing automation work. We scope and quote after the initial call — no surprises.
Let's scope it
What's the work your team keeps doing by hand?
Bring one repetitive workflow to the call. We'll tell you — for free — whether it's worth automating and how.
