Do I need to sell the project myself as a referrer?

No. A simple referral can be just an introduction. Own The Conversation can then explain the Digital Twin, run the walkthrough and manage the opportunity directly. The referral model is meant to stay simple: introduce the opportunity, let the product speak for itself, and move qualified leads into a proper walkthrough. In other words, the goal is to give the client a controlled first AI layer instead of leaving the whole topic vague and undefined.
