In 2017, management at Shift, an online marketplace that uses a "high touch," concierge approach to buy and sell used cars, was formulating plans for the San Francisco-based startup's next phase of expansion. One option was to preserve Shift's current business model and grow through geographic expansion. Another option was to decentralize more tasks to sellers and/or buyers, for example, management of inspections and repairs. While decentralizing tasks would reduce Shift's labor per transaction and thereby improve the venture's unit economics and its scalability, Shift might risk undermining users' trust by handing off responsibility for critical tasks.
