Market Intelligence

What moved the name, summarised and tied back to the signal — so the rationale and the headline are in the same place.

Why we built it

Between us we have spent most of two decades building the trading platforms that institutions run on — execution systems, client connectivity, recommendation engines. The tooling on that side of the market is very good at telling a professional what is happening and why it matters.

Almost none of that reaches an individual trader. What reaches them instead is a signal with no reasoning attached, or a screener that returns four hundred names and leaves the judgement entirely to them.

Jumerius is the part in between: the setup, the grade, the reasoning behind the grade, and the history to check it against — in one place, in language a person can argue with. We are deliberately not in the advice business. We help users get confidence before executing their trading strategies.

The team

Who is behind Jumerius

Derek Chong

Co-Founder · CEO

Twenty-two years building trading platforms and technology across equities, FX and crypto, in banking, fintech and Web3.

He now builds multi-agent systems for finance and technology, including a twenty-five-agent software organisation that enforces evidence at every handoff — the same discipline that gates what ships in Jumerius.
