Why we exist

A startup is one of the most powerful ways to solve a real problem at scale.

However, great ideas rarely become great companies. Most ideas die before they are ever tested, and many that get built fail because they never become something people truly need, choose, and pay for.

That’s the gap we close. We know what it takes to turn an idea into reality and revenue, and we put that playbook in the hands of exceptional builders.

Kiuas aims to build world-defining companies from Finland.

FAQ

What is Kiuas?

Kiuas is a founder collective for ambitious builders turning ideas into high-growth companies. We work with a small group of founders and help them go from an early idea to landing customers and growing.

Is it really free?

Yes. No fees, no equity, no strings. We can offer this thanks to partners who share our mission of building more significant companies from Finland.

Who is it for?

Founders at the idea or early-stage who want to build something big. You might still be validating your idea, developing an MVP, or starting to gain traction. We care about drive, agency, and a willingness to test and learn more than your background or experience.

Is Kiuas an accelerator?

No. There’s no fixed cohort, no set curriculum, and no demo day. We work with each founder based on where they are and keep them moving toward customers and growth.

Do I need a team or a co-founder?

No. You can come as an individual with an idea, or as a team already building. What matters is the ambition and the work, not the setup.

Do I need to be based in Otaniemi?

No. There’s a workspace and community in Otaniemi if you want it, but we work in a flexible, hybrid way, so being at the office every day isn’t a requirement.

How do I join?
