Built by founders, for founders

Or: why pay for SaaS when open source exists?

The Founder

Romain's been playing with code since he was 12. Fast forward through a Telecom Engineering degree, architecting high-availability telco on-premise systems, digitalizing venture capital investments, co-founding a cloud based B2B Telecom Platform as a Service called Cantoo. The pattern? Every founder pays $200+/month for Zapier, HubSpot, Calendly, Notion, when open-source alternatives exist and work just as well. But nobody wants to deal with hosting them. So Kamina exists, we host the OSS tools, you stop paying SaaS subscriptions.

Our Mission

Here's the deal: you're paying $200-500/month for SaaS tools when open-source alternatives exist. Activepieces instead of Zapier. Twenty instead of HubSpot. Cal.com instead of Calendly. Same features, lower cost. We host them, you own the data. Simple.

Why Kamina?

OSS, Not SaaS

Open-source tools work. They're just annoying to host yourself. We handle the hosting so you get the benefits without the headaches.

You Actually Own It

Your data, your instance. Export whenever, migrate whenever. We're hosting it for you, not locking you in.

Stop Paying Per-User Fees

Zapier charges per task. HubSpot charges per contact. We charge one flat fee. Use it however you want.

Way Cheaper Than SaaS

€70/month for Founder Stack vs $200-500/month for Zapier + HubSpot + Calendly + Notion separately. Do the math.

Ready to stop fighting your infrastructure?

Start with Activepieces automation or wait for Founder Stack. Either way, less time on DevOps, more time shipping.
