## What it does

Scalar Field is building an agentic trading desk: one place to research an investment idea, backtest a strategy, monitor events and turn it into a live portfolio. Its distinctive technical claim is that the reasoning layer and execution layer are separate. An LLM can interpret filings or develop a thesis, while a deterministic event-driven strategy watches markets and handles execution without calling a model on every price change. The [YC profile](https://www.ycombinator.com/companies/scalar-field) describes that architecture and the current supported venues.

The fit is a quantitative researcher, trading team or technically capable investor who wants agent workflows around market data without stitching together data vendors, compute, broker APIs and portfolio state. Scalar Field currently names Robinhood, Public.com, Polymarket, Jupiter DEX and Alpaca, and says paper trading is available through Alpaca and Polymarket. That makes the first evaluation concrete: start in paper mode, inspect the data and risk
