Crowdsourcing
Crowdsourcing (not to be confused with crowdfunding) refers to obtaining input into a task or project by enlisting a large number of people, generally for free. For example, asking a Reddit sub for an opinion on a rapid prototype rather than paying for a focus group.
Gamification
Through gamification, a startup can add a game-layer to a product or service that encourages users (via Motivation Theory) to take a specific action in exchange for a reward.
Lean Startup
A method used to validate a business concept quickly and cheaply when founding a new company or introducing a new product.
Value Proposition
A startup’s value proposition (also expressed as Unique Selling Point/USP) is what makes the business uniquely attractive to customers and investors.
