Quick answer

What is vertical SaaS?

Vertical SaaS is software built for one industry, such as clinics, schools, construction firms or logistics operators, rather than for every business. It wins by modelling industry workflows, regulations and integrations that horizontal tools ignore. Stack18 builds vertical SaaS products with founders who know the industry, from discovery and MVP to multi-tenant scale and embedded payments.
