YieldStack's answer:

GEX Horizon's answer
GEX Horizon was built out of frustration with the status quo in options analytics.

We believed that every trader deserves to see where the dealers are positioned — in real-time, without a paywall. So we built the WebSocket infrastructure, the real-time GEX computation engine, and the intuitive dashboards that make institutional-grade options market microstructure data accessible to everyone. The result is GEX Horizon — free, real-time, and built for the traders who need it most.
YieldStack's answer:
Rommin Adl and Daniel Chesney founded YieldStack to simplify commercial real estate financing. The platform brings deal preparation, lender matching, offer comparison, and closing coordination into one workflow, combining AI-assisted analysis with human brokerage expertise.
