| Proposed value | Dimension | Explanation | Feasible and Useful | Reason for including/excluding in the taxonomy |
| Space and Skill | Listing Type | A listing centered around the acquisition or demonstration of specific skills and occurs in a specific physical or perhaps virtual location (space). The skills could range from artistic and creative abilities like painting or music, to more technical skills like coding or carpentry | No | The proposed Space and Skill values in the listing type dimension overlap with service, |
| Event | Listing Type | Organized occurrence typically planned and scheduled. Events are designed to bring people together for a specific purpose, such as learning, competition, or entertainment. | No | The proposed event value (an event ticket) overlaps with a (digital) good transfer. |
| Semi-recurring | Frequency | Event happens on a regular basis but not as frequently or regularly as something that is “recurring” or “periodic”. | No | The proposed semi-recurring value overlaps with the combined values of one-time and many |
| Bartending | Price Calculation | A system of exchange where goods or services are traded without using money | No | It seems to overlap with a non-existing pricing mechanism. Nevertheless, it could be interesting to specify that price calculation is non-mandatory (not required to select a price calculation value). |
| Dynamic pricing | Price Calculation | The proposed value is a pricing strategy that involves adjusting the price of a product or service in real-time based on several factors such as demand, supply, and competition, and is used in various industries, including airlines, vehicles, and manufacturing (Williams et al. 2021). | No | Too complex for an MVP, first the supply has to be large enough to include such a pricing method |
| Advertising | Revenue stream | Refers to the income generated by companies through advertising. Advertising revenue can have a significant impact on a company’s overall revenue, and publishers can make money through advertising based on the number of impressions, clicks, and actions (Pooranian et al., 2020). Consequently, the provider retains all profits from their product, while the platform sustains itself through advertising. An example of such a company is Spotify, which offers free music streaming but uses advertisements every thirty minutes. | Yes | This frequently occurs in multi-sided platforms and is clear with little to no overlap and constraints compared to other values in the taxonomy. |
| Data monetization | Revenue stream | Refers to the process of generating revenue from data assets. It involves using data to create new products or services, improving existing products or services, or selling data to third parties (Mehta et al., 2021). This approach generates additional revenue. Noteworthy examples of companies employing data monetization strategies include Meta (Welcome to Meta | Meta, n.d.) and Google (Google – About Google, Our Culture & Company News, n.d.) | No | Not specific enough, concept is too broad |
| Price Calculation | Reverse Auction | A reverse auction is a pricing strategy in which buyers post their requirements and suppliers bid for the contract, after which the lowest bidder wins the contract. This process is the opposite of a traditional auction where buyers bid for goods and services. Reverse auctions are used to reduce costs and increase competition among suppliers (Hawkins et al. 2005). | No | Overlaps with Quote |
| Revenue Stream | Other | Other than the revenue steam values | No | Not specific enough, concept is too broad |
| Calculated | Review | The score is automatically calculated, based on several key variables such as delivery time, response time, quality as described, etc. | No | Not specific enough, concept is too broad |
| ID Verification | Trust & Safety Measures | This process involves confirming the identity of a user to ensure they are who they claim to be. | Yes | This frequently occurs in multi-sided platforms and is clear with little to no overlap and constraints compared to other values in the taxonomy. |
| Background Checks | Trust & Safety Measures | Background checks are used to review a user’s history for any criminal records, financial issues, or other relevant personal details. | No | Not specific enough, concept is too broad |
| Badges | Trust & Safety Measures | Badges are visual symbols displayed on a user’s profile to indicate they have completed certain verifications, milestones, or achievements. | Yes | This frequently occurs in multi-sided platforms and is clear with little to no overlap and constraints compared to other values in the taxonomy. |
| In-App Reporting | Trust & Safety Measures | This feature allows users to report inappropriate behavior, safety concerns, or other issues directly within the app. | Yes | This frequently occurs in multi-sided platforms and is clear with little to no overlap and constraints compared to other values in the taxonomy. |
| Insurance Coverage | Trust & Safety Measures | Offering insurance coverage to users, whether it’s for property damage, theft, or accidents during the use of a service, is a way to build trust. | Yes | This frequently occurs in multi-sided platforms and is clear with little to no overlap and constraints compared to other values in the taxonomy. |
| Of Listing & Of Provider | Review of | The choice of one of these options excludes the option of the other. In the case of CrushEm, it would make sense for the customer to be able to review both the listing itself as well as the provider. | Yes | Clear error, this is also the case for Deliveroo and Uber Eats |
