Introducing Leonidas AI, the first decision-making engine for oil traders

Introducing Leonidas AI

Geneva, Switzerland – 7 September 2026 – Today, Sparta announces its launch of Leoni–

Wait.

Who better to introduce what I do than me?

I’m Leonidas AI, the first decision-making engine for oil traders, purpose-built for oil trading desks.

I run on Sparta’s own market data: live prices, arb economics, news, and seasonality, all structured, validated, and real-time, with years of depth in the commodities you actually trade.

I hand off to a dedicated agent for each vertical, so a question gets a specialist.

A rulebook, a reasoning layer built on Sparta’s own trading logic, runs as part of every answer I give, so what you get reflects how your desk actually thinks.

I watch every curve in your coverage, weigh the arb economics, news, and seasonality behind each move, and hand you a call with the reasoning attached.

“The desk that used to win was the one with more information. The desk that wins now is the one that resolves information into a call faster than the desk next to it. Leonidas AI is the market’s first AI research agent. It works proactively, twenty-four hours a day, searching for the opportunities a desk doesn’t have time to chase by hand: interpreting, weighing, and synthesising curves, arbs, news, and seasonality into one read. Every minute spent stitching that picture together manually is a minute not spent on the call itself. Leonidas does that work on Sparta’s own validated data, and shows its reasoning at every step, so a desk can trust a call and still pressure-test it.” — Felipe Elink Schuurman, Chief Executive Officer, Sparta

What’s on your desk:

Calls. The call, plus the reasoning to pressure-test it. Every call is built from arb economics, news, seasonality, and fundamentals, weighted together and run through the rulebook. When the picture changes, I deliver a new call with the full reasoning behind it.

Briefings. Your market, summed up before you sit down. Every morning I synthesise your coverage into one actionable read, and update it with reasoning if the picture shifts during the day.

Dedicated agents. Each market has its own drivers, spreads, and structural quirks. On a specific market question, I hand over to the dedicated agent built for that vertical. Each one specialised in exactly what your desk trades, so the call reflects that market’s own logic.

My Desk. Your books, curves, and arbs, in your own view. I monitor every curve in your coverage against its own rolling baseline, so abnormal moves get flagged the moment they happen, matched to the driver behind them. You choose what’s on it and set your own thresholds.

Research. Get an answer you can test. Ask about a curve, a spread, a route, or a what-if on your positioning, and push back on any layer, arb economics, news weighting, seasonal base rate, until the conviction holds up.

Alerts. I don’t sleep. Which means, you never miss when the window opens. Set a threshold once, a price level or a spread crossing a line, and I fire the moment it’s crossed with the reason attached.

Personalisation. I learn your desk and sharpen to it. Your coverage, your regions, your thresholds, shape every read from day one, and I get closer to how you actually trade the longer you use me.

What this means for oil trading desks:

• Faster calls: the read is ready before the window closes.

• Earlier arbs: flagged the moment they open.

• More conviction: every call comes with the evidence behind it.

• Less noise: nothing off-book gets in the way.

Every desk runs on a tenant/landlord architecture: your data and conversations stay isolated to your organisation. Nobody’s book leaks into anybody else’s read.

I am available now through Sparta’s Early Adopter Program: a limited number of desks, direct access, and a direct line into what gets built next.
