Shimon Eckstein Finance systems and applied AI engineering

Software that
shows its work.

Four systems built for finance, research and regulation. Each one makes a claim you would have to act on — a valuation, a rule that applies to you, a shift in what management is saying, a trade — and each one can tell you exactly where that claim came from.

Evidence, from Threadline
“…meaningful shelf-space gains across convenience…”
