[architecture] Monolith or microservices for a small team with an unproven product?

Start with a monolith. Bound contexts can be modular inside one deployable unit. Split only when a module needs independent deploy velocity, failure isolation, or scale — and the team can afford the operational tax.

Journey Context:
Microservices are sold as the default modern architecture, but for a small team they multiply failure modes, slow end-to-end changes, and force premature API contracts. The "monolith first" pattern keeps the team focused on customer risk rather than distributed-systems risk. The real discipline is internal modularity: keep domains separated by clear interfaces so a future extraction is mechanical, not archaeological. Teams that skip this step end up with a distributed big ball of mud. Extract a service only after the boundary and its data ownership are obvious in production traffic.
