02 · Web & Product Build

From first version to a product that can scale.

Custom SaaS builds with clean architecture and real security from the start — so the product you launch is the product you can grow.

Why it matters

Where this usually goes wrong — and what we do instead.

The leak

What it costs you today

The expensive SaaS mistake is shipping an MVP that cannot survive its own success. Auth, tenancy, billing and permissions get bolted on later, and the rewrite costs more than the first build.

The rebuild

How we approach it

We define the data model, tenancy and permissions boundary up front, then ship the smallest version that proves the product. Boring, well-understood architecture is a feature.

What you get

Everything included in SaaS Application Development.

Scoped before the work starts, delivered in a measured sprint, and handed over documented — so nothing depends on us being in the room.

01

Architecture & data model

Tenancy, permissions and data boundaries decided before the first screen is built.

02

MVP scope definition

The smallest version that proves the product, agreed in writing to keep the build honest.

03

Application build

Typed, tested, component-based implementation your team can extend.

04

Authentication & authorisation

Roles, sessions and access rules implemented as first-class concerns.

05

Billing & subscription plumbing

Plans, limits and entitlement checks wired in from the start.

06

Observability

Logging, error tracking and performance monitoring before real users arrive.

How it runs

Four stages. Measured from day one.

The same operating rhythm on every engagement, so you always know what is happening and what comes next.

01

Define the boundary

Data model, tenancy, roles and the scope of v1, all agreed in writing.

02

Build the core

Ship the thinnest end-to-end slice that a real user can complete.

03

Harden

Security, error handling, tests and monitoring brought up to production standard.

04

Extend

Add capability against real usage, on architecture designed to absorb it.

Proof

Track record across every engagement.

Every engagement is measured from day one. These figures are across the whole practice rather than a single campaign picked to flatter.

01How long does an MVP take?

It depends entirely on the scope boundary, which is why we define it in writing first. A tight first version that proves the core loop is the goal — not a broad feature list shipped late.

02Do you take over existing codebases?

Sometimes. We review the architecture first and give an honest assessment: extend it if the foundation is sound, rebuild the specific part that is the constraint if it is not.

03How does an engagement start?

Always with the free 30-minute growth audit. We map traffic, offer, page and follow-up, then name the single biggest constraint. You leave with a clear next move whether or not we end up working together.

04What does it cost?

Three documented models: task-based from $5/hour with no minimum commitment, a Growth Sprint from $1.5k per sprint (typically 4–8 weeks), and a Growth Partner retainer from $2.5k per month, cancellable after 90 days.

05What do you need from me?

Access to the accounts and analytics, one decision-maker who can approve work, and a short weekly review. Everything else — build, production, reporting — stays on our side.
