Lead qualification & follow-up
A new lead is enriched, scored, and sent a personal reply, then a meeting is booked. Every inquiry handled before it goes cold.
Custom AI agents
and workflow automation,
built for your business.
Every company pays skilled people for routine work.
Our systems are saving their owners hundreds of hours every month.
What we do
AI systems for the work
that repeats.
Joinery builds AI agents that take over repetitive office work inside the tools your company already runs: answering, drafting, reading, booking, posting.

01
Every inquiry answered, same day.
The system picks up calls, writes replies to routine emails the way your team writes them, and puts appointments straight into the calendar. Your team reads the drafts each morning and hits send.
02
Paperwork that enters itself.
Invoices, orders and forms are read and typed into your systems automatically, instead of by hand. A person gives the final okay on every entry.
03
Enter it once. It shows up everywhere.
Customer details, orders and appointments flow between the programs you already use, so nobody copies the same information into three different tools.

The people
Our team.
A small, senior team that designs, builds and runs the systems we deliver.
Frederik Theissen
Founder
Frederik is a former academic researcher who has spent a decade building data and AI systems that run in production: analysis systems used in neuroscience research, quantitative risk at a crypto hedge fund, and AI workflow automation for the analyst team of a Swiss market-intelligence firm. He has built with large language models daily since December 2022. German and English. Based in Dubai, working across DACH and international markets.
Felix Dietze
Partner
Felix is a computer scientist from RWTH Aachen who works at the deep end of AI: the kind of engineer who trains models rather than just applying them. He has a decade of production software behind him, as principal engineer at a pricing-AI startup and co-founder and CEO of a startup of his own, and has built everything from trading bots and games to interfaces that update themselves. Rust first, many languages beside it. German and English.

Example workflows.
Three workflows we build often, shown start to finish. This is the work your team stops doing by hand.
Finance & ops
Invoice autopilot
An invoice arrives and Joinery reads it, matches the PO, and posts it to the books. A person approves with one tap. Twelve minutes becomes seconds.
Home services
Missed-call text-back
A missed call turns into a booked job, automatically. Joinery texts the customer back in seconds, answers, and fills the slot on the calendar.

Engagement
How an engagement works.
One fixed price, quoted after the first call. You own what we build, with no lock-in and no per-user fees.
A paid working session on your processes. You leave with a ranked plan: where AI pays off, what it costs to build, and what to skip. The fee is credited to any project we build together.
The build
One working system, built in the tools you already use, tested and documented, and handed over as yours.
Ongoing care
Optional monthly support after handover, as your needs grow.
Founding-client terms available for the first cohort. Mention it on your first call.
FAQ
The questions
buyers actually ask.
Anything missing? Bring it to the call.
We already use ChatGPT. What more would this do?
ChatGPT helps when someone sits down and asks it something. A Joinery system works on its own: it reads the inbox overnight, drafts the replies, enters the invoices, and answers the phone while your team is busy. Your people approve the results instead of doing the typing.
How long does a typical build take?
Most single-workflow builds go live in two to three weeks, connected systems in four to six. Whatever the scope, something real is running within the first month. We do not do six-month roadmaps.
Do I need technical knowledge to work with you?
No. We handle everything: planning, building, connecting your tools, going live, and training your team. Your team answers a handful of questions about how you work and grants access to the tools you want connected. That is it.
Does this replace my team?
No. The system takes over the repetitive steps: retyping, routing, first drafts. Your people keep the judgment calls and the customer relationships, and get their hours back for the work that grows the business.
Who owns the workflows and code?
You do. You own every workflow, agent, prompt, and connection we build for you. No lock-in, no monthly per-user fees on top of the build price. If you ever leave Joinery, you take everything with you.
What about data security and compliance?
GDPR-compliant by default. We build on established infrastructure (OpenAI, Anthropic, n8n, your own cloud where preferred), and for regulated industries entirely inside your own environment. Your data stays under your control.
What tools do you build with?
Whatever fits the job: n8n, Make and Zapier for the plumbing, OpenAI and Anthropic models for the thinking, custom code where off-the-shelf falls short. We pick the simplest tool that delivers.
What if my needs grow after launch?
That is what the optional monthly retainers are for: monitoring, model updates, and new builds as you find the next workflow worth automating. You can also engage us project by project. No long lock-in contracts.
Is Joinery the right fit for my business?
The best fit is an owner-led business or lean team, roughly ten to a few hundred people, with at least one repeating workflow that eats serious time, and a decision-maker who moves in days rather than quarters. If that is not you, we will say so honestly on the free call.
Built. Intelligently. Lightning fast.
