The situation
Continuum Digital Twin is Common Ground's own case study in what it takes to build an advanced digital twin: a person's voice, their credibility record, their wins, who they are, their professional profiles, their work history, their opinions, and a vault for what they choose to keep. It is a standalone internal process, running now, and it doubles as a case study because Common Ground is its own testing ground for work like this: build it on the firm's own people first, then decide what travels to a client.
The corpus behind it is per person: texts, email and voice recordings, running to millions of words once a full pass is done. Jesse's is the first full corpus: 38,494 texts, 34,025 sent emails back to 2007, 11,673 raw dictations and 5,480 spoken turns from recordings, about 3.4 million words total. Alex, Jimmy and Robbie each have a starter voice file built from their own messages to Jesse; their own full passes are still pending.
Two parts of the line are written up in full in Common Ground's systems room. A voice engine, built first for a partner's own drafts, checks its output against a counted fingerprint of that partner's real writing. A credibility register, built first to stop the firm's own claims from drifting across its own public pages, tracks every claim with a status and a source. Both live in Common Ground's systems room, and this room links out to both rather than repeating their detail.
The lab started narrower than a checklist. In June 2026 the working concept was one idea: estate planning moves money on a schedule and moves none of a person's judgment, so the founder built a capture stack on his own life to test whether that gap could be closed. That concept is still active, and it is the origin story below. The rest of this room is the wider question it grew into: what does an advanced digital twin need, item by item, and in what order do you build it.
A digital twin has to sound like the person, say only what it can back up, and know what stays private versus what can go public. Most attempts at this skip straight to a demo and never test any of it against a real person's own record, so the gaps only show up after the twin is already talking to someone.
Turned the internal build into a checklist of every input a real twin needs and a workflow for building one, in the order Common Ground ran it: capture, mine, structure, verify, voice-test, publish rules. Each item was tested on the firm's own people and its own public record before it went anywhere near a client.
Every input on the checklist was built and run on the firm's own people first. The voice engine is checked by a blind test the person takes cold, the credibility register gives every claim a status and a source, and the June 2026 concept that started the lab is still running.
