Wooxy at City Resilience Hack 2026: Building Safer Cities
A city's next big test could be a blackout, a storm, or a sudden spike in demand on emergency services. The teams that show up ready make all the difference.
That's exactly the kind of challenge City Resilience Hack 2026 was built to solve. This September, wooxy will be right there in the room helping build the answer.
We've been selected to run our own track at this year's event in Tallinn. We still haven't quite processed it, honestly.
What Is City Resilience Hack 2026?
City Resilience Hack 2026 runs September 24 and 25 at the Energy Discovery Centre in Tallinn, Estonia. The City of Tallinn and Tehnopol organize it together, inside Estonian Defence Week. Wooxy will be one of the teams in the room, running a track alongside mentors who've managed real crises for a living.
Tallinn isn't running the show alone. Valencia, Helsinki, Dnipro, and Lviv each bring a real problem from their own city hall.
"The event gives Valencia a place to test ideas. Ideas that could genuinely improve how the city serves its residents." — Paula Llobet, Valencia's innovation councillor, Startup Valencia
Mentors on-site aren't generic startup coaches either. They include Siim Alatalu, who spent over a decade shaping Estonia's national cyber defence policy. Also Jako Vernik, who has run several of Estonia's largest national crisis exercises. Feedback here comes from people who've actually managed a crisis, not just simulated one.
The prize fund is €75,000. Winners get pilot access with a real city, plus a seat in Tehnopol's startup acceleration program. The event has already picked up coverage from SmartCitiesWorld, the industry outlet that tracks smart-city projects across Europe.
Did you know? A BMJ Innovations study that tracked 356 hackathon teams found 40% either kept building their project afterward or planned to. Almost 5% went on to form a real company.
4 Challenge Tracks at City Resilience Hack 2026
Every team at City Resilience Hack picks one of four challenge tracks. Each one maps to a gap a partner city is dealing with right now, and none of them are hypothetical.
| Challenge track | What it covers | Cities feeling it most |
|---|---|---|
| Smart & connected platforms | Real-time situational awareness, breaking down data silos between agencies and sensors | Tallinn, Helsinki, Dnipro, Valencia |
| Resilient critical systems | Energy and infrastructure resilience, catching drone and hybrid threats early | Tallinn, Valencia, Lviv |
| Crisis communication | Getting the right alert to the right person fast, two-way citizen feedback | Tallinn, Helsinki, Lviv, Valencia, Dnipro |
| Health & social resilience | Civilian-military healthcare coordination, medical logistics under pressure | Lviv, Dnipro |
Each track connects to something already happening in the real world. The market for smart-city platforms is growing fast, expected to jump from $24.5 billion to $39.5 billion by 2030. Resilient infrastructure is not just theory either. In March 2026, a drone from Russian airspace hit a power station in Auvere, Estonia.
That's exactly why this track exists.
Crisis communication is growing fast too. The market for mass alert systems is set to grow from about $10 billion to $26 billion by 2026.
Health resilience got tested for real during the April 2025 blackout in Spain and Portugal. Doctors in Lisbon had to write prescriptions by hand, because the power, phones, and internet all went out at once.
Teams need at least three people, and organizers are explicitly looking beyond developers, into design, health, logistics, and defence backgrounds too. Applications close September 10, and you can apply directly here.
How Wooxy Supports Crisis Communication
Leading a track for two city governments isn't like walking a business through a demo. What City Resilience Hack needs, messaging that's fast, trustworthy, and impossible to fake, is basically what wooxy already does every day. Just with much higher stakes.
We already send across five channels from one account, so an urgent alert never gets stuck waiting behind a routine update. It's the same setup governments increasingly rely on to reach citizens. Every message authenticates itself first, and access is locked down by role. Unglamorous stuff, but it's exactly what matters the one time a message absolutely has to be real.
What we're most curious to bring into the room is AMI, our built-in AI. It turns a real event into an automated message in seconds, the same instinct a city needs when minutes decide who gets help on time.
How Governments Can Communicate With Citizens
Crisis communication is one end of the spectrum. On the other end sit the small, routine notices cities send constantly:
- Road closures and detours
- Utility shutoffs and boil-water advisories
- Transit delays and rerouted lines
- New service announcements and policy changes
All of them are just as easy to get wrong as a crisis alert, just with lower stakes per message and higher volume overall.
A resident who isn't warned before something changes finds out the hard way, then calls the city to ask why. New Yorkers alone contacted 311 more than 37 million times last fiscal year across calls, the app, and texts, a lot of it just people asking what's going on.
Did you know? The 311 mobile app channel grew 17% year over year, while text contacts actually dropped 12% over the same period. People reach for whatever channel answers fastest, and a city that doesn't send the answer first loses that race by default.
We put together a simple two-message SMS workflow as one example of how this gets automated:
- Alert fires the moment a status changes in the city's own system, no manual sending
- Confirmation fires off a second trigger once the situation resolves
- Segment filtered down to only the residents it actually affects, whether that's one street or a whole utility zone
The road closure example is just that, an example. The same trigger-and-segment pattern works for a water shutoff, a transit disruption, or any other routine notice a department sends on repeat.
Wooxy Hachaton Experience
Outside the hackathon room, this kind of building isn't new for us either. This isn't wooxy's first hackathon, and it clearly won't be the last. In June, we hosted two events during New York Tech Week 2026 at Pace University's Seidenberg School. An AI-retention workshop, and a hackathon built around the future of customer retention.
We walked in expecting a solid turnout. We walked out already talking about the next one. Watching founders, developers, and product people turn a rough idea into something real, in one weekend, is genuinely addictive.
We want more of that, not less. City Resilience Hack is exactly the kind of room we wanted to be back in.
Did you know? GroupMe, the group-messaging app Skype later acquired, was born at a TechCrunch Disrupt hackathon in New York. It's proof that a good weekend, a real problem, and the right room can genuinely build something that lasts.

What We Built at City Resilience Hack 2026
We came to City Resilience Hack with one question. What happens when the alert reaches an entire district, but the actual problem is on one street?
Over two intensive days in Tallinn, we tested that question with city representatives and crisis-response professionals. Cybersecurity experts, defence experts, and mentors from Tallinn, Helsinki, Valencia, and the other participating cities all weighed in too. The concept changed a lot.
Those conversations sharpened what actually matters in city communication:
- Target the right residents instead of alerting an entire district
- Use the channels people already check: email, SMS, push, Telegram, and Viber
- Send the message while it's still useful, not after the moment has passed
- Keep every alert relevant to the exact location and situation
- Make the whole flow work before, during, and after an incident, not just in the moment
We also realized this problem goes far beyond major emergencies. A blocked street, a water outage, a transit disruption, a local safety issue, they all boil down to the same challenge. How does a city get the right information to exactly the people who need it?
That question became our biggest takeaway from the two days. The feedback we got pushed our original idea into something sharper: targeted, multichannel communication between cities and the people living in them.
Huge thanks to Tehnopol, the city mentors, and everyone we met over those two days. They pushed the idea further than we expected. The hackathon is over, but the work on the concept isn't. We're continuing to build on it from here.
What Comes Next?
City Resilience Hack 2026 gave us something more useful than a finished answer: a clearer understanding of the problem and a much stronger direction for solving it.
We’re continuing to explore how Wooxy can help cities communicate with residents faster, more precisely and through the channels that work best for them.
Tallinn was an important step in that process — and definitely not the last one.
We’ll keep sharing what we learn as the idea develops.
