You’ve probably heard the word “hackathon” thrown around in tech circles. But what actually is one? Is it about hacking into systems? Writing code at lightning speed? Or just an espresso-fuelled all-nighter? Let’s clear things up.

At La Fosse Academy, we train the next generation of tech professionals. That means we know what it’s really like to work in the industry – and why hackathons are such a brilliant way to build skills, grow confidence and get stuck into real-world challenges…

..So, what is a hackathon?

A hackathon is an event (like a marathon) where people come together across a set period of time to solve problems using technology. That could mean designing an app, experimenting with data, or building a tool that makes everyday life a little easier.

Despite the misleading name, there’s nothing sinister going on – we’re talking about creativity and coding, not cybercrime.

Hackathons usually take place over one or two days, and they’re known for their fast pace and collaborative energy. You’ll often see people working in teams, bouncing around ideas, and building prototypes, all in the name of innovation.

What happens at a hackathon?

Most hackathons kick off with a challenge or theme, like “design a tool that improves mental wellbeing” or “make public transport better”.

Once the challenge is live, you’ll either join a team, or build one on the day. Then it’s time to brainstorm. Ideas fly around quickly, people sketch out plans, and teams decide what they want to create.

The bulk of the event is focused on building – whether that’s coding, designing, testing, or all three. But, you don’t need to know everything. In fact, most teams are made up of people with a mix of skills and experience, allowing you to both lead and learn during the process.

At the end, there’s usually a chance to present what you’ve created. Some hackathons are competitive, with judges and prizes, while others are more about showcasing what’s possible.

Whatever the format, expect a lot of problem-solving, teamwork, and a good dose of caffeine.

Why do hackathons matter?

Hackathons give people the chance to apply what they’ve learned in a real setting. You’re not just sitting in a classroom or working through theory – you’re delving into a real challenge, learning from others and seeing how your ideas take shape.

For many of our trainees, it’s one of the first times they get to work as part of a tech team. You’ll learn how to listen, share ideas, manage your time, and keep going when things don’t quite go to plan. That experience is invaluable… and a real confidence boost when things go well.

Tech hackathons are also a great place to network, try something new, and get noticed. Many companies use hackathons to spot potential – not just in coding ability, but in problem-solving, collaboration, and attitude.

Who can take part in a hackathon?

Hackathons are open to all, and you don’t need to be a senior developer to get involved. You’ll often find designers, testers, project managers, and people who are simply curious, all working together.

Some events are geared towards professionals, but many are designed specifically for people who are new to the industry. Organisers often provide support and guidance throughout too, so you’re never on your own.

If you’re just getting started in tech (or thinking about it), a hackathon is a brilliant way to put yourself out there and learn ‘on the job’.

Thinking of running a tech hackathon?

You don’t need a huge budget or high-end equipment to run a hackathon. The best ones start with a clear challenge, a group of motivated people, and an open space to try things out.

Hackathons aren’t about slick presentations or perfectly coded apps. They’re about creative thinking, collaboration, and solving problems that matter.

So, whether you’re part of a professional tech team or simply a curious thinker, organising your own hackathon can bring people together and spark fresh ideas.

Ready to get involved?

At La Fosse Academy, hackathons are a core part of how we help people build real industry experience. Our trainees don’t just learn about the latest technologies – they apply them in practical settings, working together to tackle challenges that mirror the reality of working in tech.

We believe that ability comes from everywhere. Our mission is to support people from all backgrounds to build confidence, gain experience and start successful tech careers.

So, if you’re looking for the kind of learning that goes beyond the book, La Fosse Academy is the place to start.
