What's Start hack?

For a day and a half, the brightest builders, coders and designers come together to push limits, crack real-world challenges, and bring bold ideas to life. It’s where tech meets business, where creativity meets execution, and where you find teammates who can turn a crazy late-night idea into something that actually works by sunrise. You’ll code, pitch, prototype, fail fast, fix faster — and in the end, show a jury what happens when sharp minds don’t sleep for 36 hours.

You should join if you want to test yourself against the toughest problems, learn from people who are just as ambitious (and maybe as stubborn) as you, and walk away with new skills, new friends, and maybe even the spark for your next startup. If you’ve been waiting for the perfect excuse to go all-in, this is it. Bring your laptop, your energy, your brain — and nothing else. The rest? We’ll hack it.
