Independent products. Selective partnerships.

Cyrillian builds software we want to exist.

Games, systems for financial markets, apps, AI systems, and tools that do not fit cleanly into a category. We build our own products, and sometimes work with clients or partners when the work is worth doing. We fight for the user.

Expertise map

Built across hard domains.

The work moves between reasoning, markets, AI, workflow software, scientific systems, and games. Some areas are shipped proof. Some are technical range. Some are where we are deliberately leaning next.

How we work

Empathy is a product constraint.

We do not hide hard problems behind soft interfaces. We build the right interface to make hard problems easier.

Problem

Work in messy domains

Markets, games, scientific systems, and AI products all punish generic interfaces.

Model

Keep the work visible

Show state, assumptions, and intermediate results where they matter.

Judgment

Respect the operator

Leave judgment with the person using the tool. Automation should support the decision, not swallow it.

Action

Ship useful tools

The product is done when it helps someone take the next step.
