What should I collect first to start a walkthrough?

Gather the client’s basics: their products or services, the most common customer questions, approved content you can reuse, and the website URL plus branding. These materials let you map what the AI would need to understand the business and where gaps exist. Also confirm the intended partner role (referral, resale, or white-label) and the scope of the walkthrough. With those in place, you can conduct a focused demonstration that uses actual pages and signals (discovery, retrieval, and referrals) to illustrate how a Digital Twin could help.
