Ep#73: The Digital Twin for Work — What Founders Don’t Understand with David Shim
from Startups Decoded · host andy walsh
Most companies believe they run on strategy. They actually run on conversations, and those conversations vanish the moment the call ends.David Shim watched this happen from the inside while running Foursquare, sitting in meetings where half the room was camera off, on mute, essentially absent. He called it Ghost Mode. That observation became the founding insight for Read AI, and it’s a sharper diagnosis of organizational dysfunction than most founders ever put into words.What David built isn’t just a note-taker. It’s a system of action, one that captures decisions, tracks follow-through, and over time builds a working model of how you think and operate. The digital twin concept he walks through here is the logical endpoint of that: an AI that knows your priorities, your patterns, and your blind spots, and starts filling the gaps before you even notice them.For founders, the practical takeaway is immediate. Every conversation your team has is institutional memory, and right now most of it is leaking out of your company every single day. This episode is about what it looks like when you actually stop that.EPISODE OUTLINE1. From stock ticker to stockbroker at 17 2. Placed, Snap, and the location data bet 3.
