The Startup Hack
Think like a founder. Not just a hacker.
This is not your usual hackathon, and we're not just looking for the best coders. We're looking for founders.
Spend 24 hours solving real challenges from Helsinki's startup scene. And if you're already building something of your own? Antler will be there — book a slot, show them what you've got.
What makes this different? You will:
Work on real startup challenges (in teams of up to three)
Get direct access to founders as mentors
Learn how startups think, build, and prioritize
Create something that could go beyond the hackathon
This is your chance to experience what it's like to build inside a startup: fast-paced, ambitious, and focused on real impact.
Two ways to participate
🏢 Startup Challenges Pick a challenge from one of our challenge providers and build a real solution for their problem in 24 hours.
Challenge Providers:
CasvuAI
TaruTech
Trainer (Aalto Founder School)
