SaaS case studies: revenue and exits
SaaS (Software as a Service) is software sold as a monthly or annual subscription. Small Start records the revenue, ARR, sale prices and acquisition channels of SaaS businesses run by individuals and small teams, each with a source.
Recurring revenue makes SaaS numbers look stable. The archive also holds the other side: an MRR that decayed 90% through neglect, and a deal that died after six months of due diligence.
