How we work

We own what we build

Every product on this page is ours. We ship it, run it in production, and answer for it — no client hand-off, no throwing it over the wall.

One small team, full stack

The same people design the product, write the code, and keep the servers up. Web, mobile, infrastructure, and AI.

We ship, then we stay

Launch is the start, not the finish. We keep shipping on each product for years after the first release.

Where we came from

Before our own products, we built software for other companies. One was acquired by Atlassian. That work funds the products above and sharpens how we build them.

B6 Cloud

Productivity platform. Notion-like editor, kanban board, policy management workflows. Acquired by Atlassian.

Denis, Founder

“Eternity Cat was our founding engineering team. Two years later, Atlassian's team went through the codebase during diligence and came back with a short list of nitpicks.”

Minimo

Marketing automation platform. Email builder, visual workflow editor, a dozen of integrations. Hundreds of active users daily.

Andrea, Founder

“Eternity Cat built the first version of Minimo. Three years in, they're still the team I call when we hit something our in-house developers can't solve quickly.”

Mileva

A government-facing platform for Serbia's licensed building managers. They file documents with the state, buy and renew licenses, and pay fees directly through the system.

Milosh, building manager

“Before Mileva, half my week was couriering documents between the ministry, the bank, and twelve buildings. Now I'm running more buildings with less admin.”

Mospromstroy

ERP for a construction company running multi-million-dollar projects. On-time delivery went up 25% after rollout.

Alexey, CTO

“We tracked a 25% lift in on-time delivery after the rollout. On projects this size, that's the difference between a quarter in the black and a quarter in the red.”

GirlfriendGPT

NSFW chat with AI characters, voice, image and video generation, social features. Thousands of fans.

Enias, Founder

“Eternity Cat are amazing!”
