SaaS Platform Engineering

SaaS platforms fail at predictable points. The architecture that carries the first hundred customers rarely carries the first ten thousand, and the decisions that cause the failure are usually made early, when they seem inconsequential. We build platforms where the expensive decisions are made deliberately rather than discovered under load.

The decisions that are costly to reverse

• Tenancy model — shared or isolated data per customer, which determines your compliance story, cost per tenant and migration options
• Data model — the schema everything else depends on, and the hardest thing to change once customers hold data in it
• Authentication and permissions — enterprise buyers require SSO and granular roles, and retrofitting a permission model touches every feature
• Service boundaries — where the system splits, which governs how independently teams can work later

Most of these are invisible while a product is small and become the constraint the moment it is not.

Microservices when they are warranted

Splitting a system into services solves organisational scaling problems — letting teams deploy independently — at the cost of substantial operational complexity. For a small team, that trade is usually bad. A well-structured monolith with clean internal boundaries ships faster and can be decomposed later along those boundaries.

We start from your team size and growth expectations rather than from an architectural preference, and will recommend the simpler system when it fits.

Built for what enterprise buyers ask for

The features that unblock enterprise deals — SSO, audit logs, role-based access, data residency, uptime guarantees — are architectural. Designing for them early costs relatively little; adding them under deal pressure means rebuilding the parts that touch identity and data.
