Real-Time Customer-Facing App Builder for Sales Calls

A workflow where consultants or salespeople vibe-code a working prototype of a client's requested software feature live during the sales call to instantly close deals.

01 THE IDEA

Logan describes being on a call with a clothing brand and building a live working prototype — including virtual try-on and AI mood boarding — in real time during the customer call itself. This surfaces a distinct business model: a productized consulting service or SaaS tool that enables non-technical consultants to build live demos during sales conversations, immediately demonstrating value and collapsing the sales cycle.

This could be structured as an agency offering ('we build your MVP on the call') or a SaaS tool that packages AI Studio-style build interfaces specifically for sales/demo contexts. The unfair advantage is psychological — clients who see their idea built live are far more likely to convert than those shown mockups or pitch decks. This is effectively a sales acceleration product built on top of vibe coding infrastructure.

03 THE VERDICT

This is a high-leverage, low-capital wedge that can be started immediately as a consulting practice and evolved into a repeatable productized service. The psychological moat is strong — clients who see their idea materialize in real time convert at dramatically higher rates. With the right niche vertical focus, a single founder could build a profitable six-figure consulting practice within 90 days.
