Founders don't fail from a lack of ideas—they fail from a lack of momentum/

// 01 — Who it's for

You've built something real.
Now let's scale it.

Katalyst is not for idea-stage founders. It's for teams who have shipped, have customers, and are ready to grow fast under structured accountability.

i.

Launched MVP

A real product in market — not a prototype or a concept deck.

ii.

Early validation

Customers, pilots, or meaningful usage data — some signal that it works.

iii.

Committed team

Founders full-time on the company — no side projects.

Built inside the walls of Lappeenranta Fortress — a place that has stood for centuries, now home to companies that will define the next ones.
