Both SaaS products and custom software can create meaningful value. The right choice depends on who has the problem, how repeatable it is, and where your advantage comes from.
Choose SaaS for a shared, repeatable problem
A SaaS product makes sense when many customers have a similar need and can succeed with a common core workflow. It requires ongoing product, support, and distribution work.
Choose custom software for operational advantage
Custom software fits when your processes, data, or integrations are specific enough that generic tools create friction.
Start with the smallest useful system
Begin with the riskiest assumption and the smallest complete workflow. A focused first release creates better evidence than an oversized specification.
