Money, Pricing & Model

What's the difference between SaaS, marketplace, and transactional business models?

A starting point

SaaS = you rent software for recurring fees (predictable, high margin, sticky). Marketplace = you connect buyers and sellers and take a cut (huge upside, brutal cold-start problem). Transactional = you make money per transaction or unit sold (simple, but you re-earn every customer each time). Pick the one whose hardest problem you're actually excited to solve.
