We know how trading really works, and how it should.
Our consultants have worked both sides of an energy trading floor: the trading operation that takes the position, and the systems behind it. That is why a project does not open with three months of us learning your business.

Who we are
Consultants with a background in trading and software engineering.
In an industry where speed, precision and insight define success, too many commodity trading firms are held back by outdated systems. We know how trading really works, and how it should work.
We believe technology should be a competitive edge, not a bottleneck. We build the trading tools decisions rest on: forecasts, signals and data checks, so trading teams can make better decisions, faster. Every tool is traceable and built to evolve, so decisions rest on numbers they can stand behind.
Rossby is not just about systems. It is about people: consultants who have worked both sides, the trade and the code, in a culture that values autonomy, growth and excellence.
Who we work with
Built for firms that trade financial and physical markets.
We are not a generalist software house. Our clients are the supply, trading and risk teams of energy majors, utilities, commodity houses, banks and funds. They trade markets where storage, delivery and logistics are part of the trade, and off-the-shelf tools rarely keep up. Pick a market to see which kinds of firm trade it.

Areas of expertise
We know the trade, end to end.
Our depth is in how a commodity trading firm works, not in one vendor or language. We work across every stage of the trading lifecycle, in whichever technology that stage already runs on.
