There are four of us. Who's number five?
From Zeist we make the phone assistant for healthcare practices. Now we're looking for someone who wants more than a job: a piece of the company.

Not a job. A piece of the company.
With four people there's no department to wait for and no manager who has to sign off first.
Here you get something of your own: a market, a channel or a piece of the product. You make the calls, you see what they do for practices, and when something doesn't work, you're the one who fixes it.
That's why we look for people who enjoy building a business more than carrying out tasks. And whoever builds a piece of the company here can become a co-owner of it too. We're happy to talk about that.
What we built in recent months
This is the pace: what the practices that work with us got from us lately.

Who we're looking for
Four roles, all full-time and hybrid from Zeist. Sales and online marketing we need most.
Sales
Needed mostFull-time · Hybrid, ZeistNo sales department, no script and no lead list someone else came up with. You build how Plainwise sells, and you see your results in the company.
What you'll do
- Talking to practices whose phones are ringing off the hook every morning, and showing them it can be different.
- Helping decide which practices we go after first: GPs, dentists, pharmacies, physiotherapists or vets.
- Working out with our partners in the telecom world how we reach more practices together.
- Putting what you hear in the field straight on the founders' table, so the next release is better for it.
Online marketing
Needed mostFull-time · Hybrid, ZeistYou make sure practices find us, get what we do and want to try it themselves.
What you'll do
- Growing the website, Google and LinkedIn into channels that bring in new practices.
- Making campaigns and content about what practices go through on the phone every day.
- Measuring what works, from who tries the live demo to who books a call, and doing more of it.
Backend developer
Full-time · Hybrid, ZeistYou build everything nobody sees, so the phone simply gets answered.
What you'll do
- Building and maintaining integrations with phone systems like Xelion, Voys and Axeos.
- Working on the digital assistant that holds conversations, summarises them and sets them out as tasks.
- Building systems that keep healthcare data safe and within the EU.
Frontend developer
Full-time · Hybrid, ZeistYou build the portal practices work with every day.
What you'll do
- Building screens for tasks, callback appointments and settings that are clear at a glance, even at a busy front desk.
- Taking the guided tours and explanations in the portal further.
- Testing and refining with practices until everything speaks for itself.
How applying works

- 3
An assignment
You get an assignment like the ones you'd get here, and show us how you'd tackle it.

Decision
Then you'll hear where we stand. If it clicks, we discuss the terms.

Don't see your role?
We're always looking for good people. Tell Martijn what you'd like to do, and we'll see together whether it fits.
