Compass Labs CEO Elisabeth Duijnstee walks through how fintechs and neobanks can embed DeFi products — stablecoin yield, crypto-backed loans, and tokenized stocks — through a single non-custodial API. The briefing includes a live build in Compass Studio of a white-label USDC savings account on Base, a $5 deposit into a Gauntlet USDC Prime vault, and a tour of position reporting, segregated sub-accounts for crypto-backed credit, and an LLM-friendly docs surface designed for coding agents like Claude Code.

Toby Rush

Ideem CEO Toby Rush walks through how modern cryptography can deliver invisible possession-factor authentication for banks, neobanks, and agentic-commerce flows. The briefing covers Ideem's FIDO + multi-party-computation "chip in software" model, device-plus-passkey binding on the same challenge, and a live Android demo of app-to-app bridging where a merchant webview verifies trust with a previously enrolled Yes Bank app via a silent push and an encrypted local channel — with no human in the loop.
