Routines that already
run themselves.
For inspiration: I built these for business owners, and most of them run every day. Recognise one? Or is your time going somewhere else entirely? We'll talk it through on the call.
Payments and receipts
A payment comes in, the receipt goes out on its own, and you see at a glance who has paid.
Running at a coaching practiceHours to invoice
You text your hours in plain language. On the first of the month the draft invoices are ready in your accounts.
Built for an ad agencyDaily briefing
Every morning on your phone: who's coming, what's expiring, and what today needs from you.
Running at a gymBooking confirmer
A booking comes in, lands straight in your calendar, and your guest gets a confirmation on their own.
Built for a holiday rentalAnswer ready
For a question you get all the time, an answer is drafted in your voice. You read it, and you press send.
Running at a coaching practiceRenewal button
Your customer gets a timely message that their plan is ending, and renews themselves with one click.

Running your business is also building something that doesn't exist yet. With AI you can often start smaller and faster than you'd think. A few things I've helped build.
An AI coach on WhatsApp
A six-week programme where every participant gets personal guidance every day, with the coach in the background.
Coaching practiceA site in three languages
A new site with its own translation pipeline, so new copy appears in every language on its own.
GymDirect booking
A calendar that follows Airbnb and Booking, a request the host confirms with one click, and payment by iDEAL.
Holiday rentalDoes ChatGPT mention you?
Every month, ten real customer questions to AI assistants, and a report: are you mentioned, through which sources, and how is that shifting.
Coaching practice
I build ideas as custom work, from €1,500. It often starts with a small first version you can try straight away.
One routine off your hands.
Here's how.
Scan
Thirty minutes at your place or online. I point out which routine pays off most. You don't need to prepare anything.
Proposal
Within two working days, a one-page proposal: what the routine does, what it gives you back and what it costs. Fixed price.
Trial run
The routine runs for thirty days in real work. Anything that goes to a customer, you approve first with one tap. For as long as you like.
Keep running
I keep an eye on it. If something goes wrong, the system flags it and you hear it from me, not from a customer.
€39a month for
one routine off your hands
- Setup, one-off €395
- You only pay it after 30 days stable
- Live within a week
- Hosting, monitoring, upkeep in the €39
- Alert if something goes wrong on your phone
- Cancel any month
For the first 5 business owners: no setup fee. Just €39 a month, in return for an honest review and permission to show your routine as an example.
Do the sums yourself
These are your numbers, not my promise. How much time a routine really gives back differs per business. All prices exclude VAT.
Back each month
8.7 hours- Value of that time
- €433
- What it costs
- €39
€39 a month is 47 minutes of your time.
Custom work, from €1,500
For a routine with several connections or several people using it, or an idea you've wanted to work on for ages. Fixed price, agreed after the call. Care from €75 a month, with a monthly report. All prices exclude VAT.
98%successful runs
or you pay nothing
or you pay nothing
You only pay once it runs.
- Trial month. If your routine doesn't reach 98 percent successful runs in the first thirty days, or you're not happy with it, you pay nothing. No setup fee, and not the first month either.
- You stay in control. Anything that goes to a customer, you approve first. Only when you want it to does it run on its own.
- Exit guarantee. If I ever stop Spare Hands, you hear it three months ahead and I hand everything over free of charge, to you or to a builder of your choice.
Stable means: at least 98 percent of runs succeed, and every error gets flagged instead of silently swallowed. With custom work, I fix it free of charge within those thirty days, or you get the build price back. I don't promise a percentage of time saved. I promise it works.
I use it myself.
Every day.
My own business runs on the same systems I build for you.
The owner teaches. The rest runs.

I'm Sjoerd. You talk to the person who builds it.
For eleven years I worked on the commercial side at T-Mobile and Odido, then at Samsung: marketing, launches and a nationwide rebrand. I know how a business does its sums, and where it gets stuck.
Since 2026 I build things myself. First for my own business, De Adempauze, which now runs on 42 processes. Now I do it for other business owners, from Zandvoort. Spare Hands is me, not an agency: you have one point of contact who knows what was built and stays with it after delivery.

Tell me what's draining you.
Or which idea keeps waiting. Thirty minutes, at your place in Zandvoort, Haarlem or Amsterdam, or online. You leave with two or three concrete ideas.
