About Curson Capital

Curson Capital is a systematic trading technology company based in Kraków, Poland, founded in July 2024 by Hieronim Kubica and Michał Szarek. We build, own and operate one platform, Curson, and we run its daily process ourselves.

We are a product company, not a services company. We do not take on client projects, consulting or agency work; we do not give investment advice; and we do not manage money for anyone else. The whole firm is the platform and the two people who build it.

The founders

Two people, two clear areas of ownership, and a rule that every change touching the investment process is reviewed by the other one.

Hieronim Kubica, PhD

Co-founder and CEO. Owns research, modelling and portfolio construction.

Hieronim trained as a mathematician and completed a doctorate before deciding that the questions he wanted to work on lived closer to data than to theorems. He moved into programming, then into machine learning, and has since worked in data science and machine-learning engineering roles across banking, insurance and industrial manufacturing, including the kind of production MLOps work where a model that is not monitored is a model that is not trusted.

At Curson Capital he owns the research side of the platform: the feature families, the forecasting models and their evaluation, and the rules that turn forecasts into a portfolio. He reviews every change that touches trading logic before it merges, and he set the standard the platform is held to: a model earns its place by beating the one in production on data neither has seen, and a signal that cannot show a lift is removed rather than kept because it sounds plausible.

Michał Szarek

Co-founder and COO. Owns infrastructure, implementation and operations.

Michał is an engineer who likes to know how things work at every layer, from the machine up to the model. He wanted to be a security researcher, was pulled into big data instead, and built his career across engineering roles in the banking sector, large-scale data platforms and MLOps, alongside independent software work. He builds systems end to end and keeps them running.

At Curson Capital he owns the platform's foundation: the Google Cloud environment and its infrastructure as code, the continuous-integration and deployment pipelines shared by every service, the brokerage integration and the execution stage that places the orders, and the monitoring that watches the daily cycle and wakes a human when it goes quiet.

Why the firm exists

The idea we started with in 2024, and what we have learned since.

Systematic investing has historically belonged to institutions. The data, the research infrastructure and the engineering discipline needed to run a strategy every day without a human in the loop are expensive, and individual investors have mostly been offered generic products instead. We started Curson Capital because we believed a small, well-engineered team could build that capability from scratch, hold it to institutional standards, and eventually make its output available to people who are not institutions.

Two years in, the belief we hold most firmly is a narrower one: the value is in the discipline, not in any single model. A platform that fails to flat when its data is incomplete, that reconciles with the broker before every trade, that records every decision with the version of everything that produced it, and that removes a feature the moment it stops earning its place, is worth more than a clever signal that nobody can audit. That is the platform we have built, and it is why we run the full cycle every day before we stake capital on it.

We publish what we ship, including the things we tried and dropped, on the news page.

How we work

The rules the process is held to. They are written down and enforced automatically, not remembered.

Every trading rule is testable on its own. The decisions live in small, isolated pieces of code that can be replayed from stored inputs, so a rule can be proven before it ever meets the market.

Each stage owns its own work. Stages hand each other finished results through explicit, versioned contracts rather than reaching into one another, so one can be replaced without disturbing the rest.

Design before build for anything non-trivial. A written design precedes an implementation, is reviewed by the other founder, and the work ends with a review of what was learned.

Everything is code and everything is reviewed. The infrastructure, the schedules and the dashboards are all in version control and applied automatically after review. There is no manual path to production.

Honest reporting. Failures raise an alert rather than being absorbed. Experiments that do not work are written up and closed, including on the public log. This site follows the same rule: what is running says running, what is planned says planned, and no performance figure appears anywhere.
