Scalability
How easily a business can grow without its costs and complexity growing at the same rate.
Example
A maths-help app can teach ten extra students with almost no extra work. A maths tutor cannot. The app is scalable. The tutor is not. Both are useful businesses; only one can serve a million customers without a million tutors.
How it fits in
A scalable business serves the tenth customer at almost the same cost as the hundredth. Software is famously scalable. Restaurants are famously not. Most businesses sit somewhere between. The point of asking 'is this scalable?' is to see whether early profits will survive growth or be eaten by it. Scalability is one of the main things investors look for when picking which businesses to back.
