I Wanted to Be
a Good Dad.
The WhatsApp Group
Had Other Ideas.

I want to be honest about something before I tell you what Donza is.

I am not the organised parent. I am the other one.

My partner carries most of the family's administrative life in her head. School events, RSVP deadlines, which child needs a costume by Thursday, who still hasn't returned the signed permission slip. She gets it right - not always, nobody does - but she is the one who usually knows. I am the one who usually doesn't.

It's not that I didn't care. I genuinely wanted to be involved, to be the kind of father who knows what's happening in his children's lives - not just the big things, but the texture of the week. Marie's swimming test. Moritz's class trip. Which birthday party we're going to this Saturday, and what we're supposed to bring. I cared about all of it. I just couldn't keep up.

The information arrives everywhere, all at once, in a format that seems designed to be lost. The school email that contained a trip deadline, buried in paragraph three of a message I scanned and closed. The WhatsApp notification from the class group - one of several I'm a member of - that I read while in a meeting and immediately forgot. The letter from school that Marie or Moritz handed me at the door, which I put somewhere responsible and have not seen since. The notification from the school app - and there are several of those now, each one requiring a separate login - that I opened, half-read, and filed away as something to deal with later. And then there's the update to the thing I already half-knew about, which cancels or changes the original information, meaning 80% of what I've half-processed is obsolete before I've done anything with it anyway.

I should say something about those school apps and portals, because they've become their own category of chaos. The platforms that schools use to communicate with parents - and there are more of them every year - are genuinely useful for the schools. For parents, they are one more place to check, one more password to remember, one more channel that might contain the one piece of information you needed. Donza doesn't magically connect to all of them. What it does is give you somewhere to put what you find, whatever the source, so that it doesn't get lost between the app and your memory.

I work in regulatory affairs for medical devices critical for hospitals across Europe - a vast infrastructure where the stakes are real and the complexity is constant. My job is turning that complexity into a language that gets everybody into the boat: I manage multiple roles, two teams, a calendar that runs back-to-back from morning to evening, jumping seamlessly from one parallel project to the next. I'm good at it. I'm professionally capable of holding a lot in my head at once without dropping things. And yet. The school stuff kept getting through. Not because I was distracted or indifferent. Because the information management problem of modern school-age family life is genuinely hard - and no tool existed for it.

The Thursday Problem

Let me give you a specific example, because the abstract version doesn't do it justice.

This year, Marie doesn't attend religion class. That means she starts school one hour later on Thursdays. One hour. Every Thursday. This should be simple. It isn't. There have been Thursdays this year where we woke her up at the wrong time - either too early, standing in the kitchen in her pyjamas an hour before she needed to be anywhere, or the other way around, suddenly scrambling. A fixed, weekly schedule change that we keep getting wrong because it lives nowhere reliable - not in our heads, not in any system that checks it against everything else we're tracking.

And that's before the cancelled lessons. Every week, reliably, there will be at least one class cancelled because a teacher is absent. A notification arrives - sometimes with a few hours' notice, sometimes less - informing you that your child can leave school an hour earlier than planned. Which sounds like good news until you realise that a child cannot simply leave school unaccompanied unless a parent actively confirms it within the given window. Miss the confirmation window and your child sits in school for an hour they didn't need to be there.

What makes this particularly maddening is that both parents receive the confirmation request independently - even if one has already confirmed. The other still gets the same message and has to dig through the same app to discover that yes, it's already handled, nothing to do. The system treats two parents as two isolated individuals rather than a household - generating double the anxiety for half the reason.

What made the whole situation worse was watching my partner go through the same pile. Both of us members of the same WhatsApp groups. Both of us doing the same mental processing of the same information, independently, inefficiently, and still collectively missing things. There was something almost absurd about it - two adults, both competent, spending real cognitive effort on the same redundant exercise, with no good outcome to show for it. It felt like a system problem, not a character problem.

And it wasn't only the events and the logistics. It was the exams. Parents of secondary school children will know the specific dread of planning a weekend away and discovering on Friday afternoon that Monday morning brings an exam your child hasn't started preparing for. Getting a reliable picture of what's coming up academically is its own parallel chaos: two children, many teachers each, some of those teachers shared between them - so when a message arrives from a teacher, you often have no idea at a glance which child it concerns. A trip to the mountains for the weekend sounds wonderful until Tuesday, when you remember what Monday holds.

The Wednesday Evening

The breaking point, for me, wasn't a dramatic single moment. It was a Wednesday evening. Picture it: both of us home, the kids eventually settled, the house quiet. We should have been able to breathe. Instead we were both staring at our phones, scrolling through separate WhatsApp threads and separate email inboxes, trying to reconstruct what the rest of the week held. Neither of us knowing, for certain, which day it was. Both of us too depleted to feel anything sharply - just that flat, specific exhaustion of people who have been managing too much for too long.

And with the exhaustion came the fights. Not the big, important arguments that couples are supposed to have - about values, about the future. The small, stupid, corrosive ones. Who forgot to RSVP. Who was supposed to have seen the email. Whose fault it was that Moritz showed up to school without the thing he needed. Fights that, in isolation, were about nothing. But that accumulated into something - a slow, grinding friction that made me wonder, at some of the harder moments, whether this family would hold together. Whether the weight of it all would eventually become too much, and I would find myself on the other side of a separation, co-parenting from a distance, doing the admin in two households instead of one.

I know I'm not alone in that. Roughly half of families in Austria and Germany end up separated. And I suspect, for many of them, the breaking point wasn't one big thing - it was a thousand small Wednesday evenings just like ours.

Which is also why Donza is not just for the family that looks like mine does today. It's for all of them. The two parents sharing a household, yes - but equally the father who gets the school emails every other week and has to piece together what he missed. The mother doing this completely alone, coordinating pickups and permissions and birthday gifts across a network of helpers with no co-pilot. The blended family where children from different relationships share a school calendar and nobody has an easy view of the whole picture. And the parent who, like me, isn't entirely sure yet which of those situations they'll end up in.

I Built Something

One of the things it quietly does, underneath all the features and the AI, is remove some of those fights from the equation. Not the important ones. Just the ones that were never really about anything except two exhausted people trying to manage too much information across too many channels with no system to help them. Those fights don't have to happen. That particular source of damage is solvable.

I had two options. Feel bad about it, or build something. I built something.

The idea was simple: take any piece of information - a forwarded email, a photographed school letter, a pasted WhatsApp message, a notification copied from a school portal - and let an AI do what AI is genuinely good at. Read the mess. Extract what matters. Tell you what to do next. Events, exams, RSVPs, payments, things to buy, forms that need signing - all pulled out automatically, tagged to the right child, without either parent having to triage the pile manually. One parent captures, both parents benefit. The redundant processing disappears.

We called it Donza - a name that earns its keep. "Done" for the obvious reason, and zack, the German word for something that happens in the blink of an eye, swiftly and without fuss. That's the promise: the hard part, done. Zack.

Those Wednesday evenings changed. That was the proof.

We shared it with a few friends. The response was immediate and, frankly, a little emotional. The parents who tried it weren't excited about the technology. They were relieved. One of them - a mother of three - said: "I didn't realise how much of my week I was spending just trying to know what was happening." That's it exactly.

For the Mothers Holding It Together

I want to say something clearly, because I think it matters and it's easy to skirt around: mothers do most of this. Not in every family, but in most of them. The invisible work of tracking school events, managing RSVPs, knowing which child needs what by which day, monitoring the school apps for last-minute changes - it lands on mothers disproportionately, and has for a long time. This isn't a small or abstract injustice. It's daily, it accumulates, and it costs women real time, real mental energy, and real professional bandwidth that fathers, on average, don't spend.

I know this because I watched it happen in my own home. My partner was doing work I wasn't doing - not because she wanted to, not because I'd asked her to, but because someone had to hold it and, imperceptibly, it had become hers.

And here is the thing I think gets lost in how this imbalance is usually described: I don't believe most fathers are ungrateful. I think most of them - most of us - feel something closer to a quiet, guilty appreciation that we don't know how to express. We see the effort. We know it's not fair. And yet we lack the voice, the tools, the moment to say it out loud. So we say nothing. And silence, over time, looks indistinguishable from taking it for granted.

That silence isn't acceptance. But I understand completely why it feels that way to the person doing the work. Donza is, in part, the thing I couldn't say out loud - made into something useful instead.

One Last Honest Thing

I'll be honest about one more thing, because this story deserves it: I don't know if it's in time for us. We are far into this journey. The fights happened. The weight was carried unevenly for years. Wounds like that don't heal because an app showed up. I don't know what the future looks like for our family, and I'm not going to pretend otherwise.

What I do know is this: there are families out there who are earlier in that journey. Younger kids. Fresher starts. The same creeping exhaustion, but not yet at the point of no return. For those families - for the parents who are still in the thick of it, still capable of changing how they share the load - Donza might actually arrive in time.

That's why I'm sharing it. Not as a success story. As an honest attempt to hand something useful to the people who still have time to use it.
