Eternity Cat

We build and run software products

Our products

Three live, one on the way. We own each one, so we keep building it after launch.

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.

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 kept improving client products for years after release — our own get the same treatment.

Where we came from

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

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.”

Minimo

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

Andrea, Founder

“Ilya built the first version of Minimo. Three years in, he's still the developer I call when we hit something our in-house developers can't solve quickly.”

GirlfriendGPT

AI companion platform: character chat, voice, image and video generation, social features. Hundreds of daily active users.

Enias, Founder

“Ilya is amazing!”

B6 Cloud

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

Founder

Ilya Evseev

Ilya spent a decade shipping software for other companies: founding engineer at B6 Cloud, then senior engineer at a UK-regulated brokerage. In 2025 he started Eternity Cat to build his own products — most of his time now goes into Hinode.
