SaaS
Software delivered as a multi-tenant web service on a subscription — the dominant business model for B2B software.
Definition
Software as a Service is the model where customers access an app over the internet on a per-seat or usage-based subscription rather than installing it locally. The vendor handles hosting, updates, and uptime. Almost all the tools cited in modern automation work — Notion, Slack, HubSpot, Linear, GitHub — are SaaS, and their APIs are the surface area automation tools integrate with.
