Business Model
What each company does and how it makes money
Marti Technologies is a Turkish urban mobility platform that operates a fleet of shared electric vehicles — primarily e-mopeds, e-bikes, and e-scooters — through a mobile app. It generates revenue primarily from ride fees paid by users for short-distance trips across its vehicle network. The company benefits from first-mover advantage and network density in Turkey's major cities, creating local scale advantages that new entrants struggle to match.
Duolingo operates a freemium language-learning platform that makes acquiring new languages accessible through gamified lessons. It generates revenue primarily through subscription fees for its premium Duolingo Super service — which removes ads and offers additional features — along with advertising and its English proficiency testing product. The company's key advantage is its massive user base and data-driven approach to optimizing engagement, creating network effects that make its platform increasingly effective for learners.
