ServiceSaaS Product Development

From an idea to a product people pay for

We take SaaS products from the first whiteboard through architecture, build and launch, then keep improving them once real users arrive and start disagreeing with your assumptions.

Who this is for
  • Founders with a validated problem and no engineering team
  • Companies productising an internal tool they already use
  • Businesses replacing a spreadsheet-and-email process with a real product
  • Funded teams who need to reach a launch date without wrecking the codebase
What is included

What you get

Product discovery

We pin down who it is for, what they do today, and the one job the first version must do better. Then we write down what we are deliberately not building.

Architecture that survives

Tenancy model, data model, auth, background work and the integration boundary. These are the decisions that are expensive to reverse, so we make them slowly and write down why.

Build in two-week slices

Something usable at the end of every increment, on a shared board you can read any day. No six-month reveal.

Security and compliance basics

Role-based access, tenant isolation tested rather than assumed, audit trails, encrypted secrets, and a data-retention answer you can give a customer.

Billing and metering

Plans, trials, upgrades, proration, invoices and usage metering. If there are AI features, cost is metered per tenant from day one.

Launch and iterate

Staged rollout, feature flags, onboarding that works without a call, and a weekly loop of watching what users actually do.

How it runs

The engagement, step by step

6 stages. Something usable at the end of each one.

  1. Stage 01

    Discovery

    Two to three weeks. Users, workflows, constraints, competitors, and a costed plan you own regardless of what you do next.

  2. Stage 02

    Foundation

    Environments, CI/CD, auth, tenancy, base data model and the first vertical slice running end to end in production.

  3. Stage 03

    Core build

    Increment by increment against the slice we agreed, with a demo and a re-plan every two weeks.

  4. Stage 04

    Hardening

    Load and failure testing, backup restore rehearsal, observability, security review and a support runbook.

  5. Stage 05

    Launch

    Staged rollout to pilot customers, live monitoring, and a fast-fix rota for the first fortnight.

  6. Stage 06

    Iterate

    Usage review, backlog re-ordering, and the boring reliability work that keeps churn low.

Questions

SaaS Product Development: common questions

For a focused product with a small integration surface, expect twelve to sixteen weeks from discovery to a pilot with real users. Heavier scope, regulated data or several system integrations push it to five or six months. Anyone promising a serious B2B SaaS in four weeks is describing a prototype, not a product.

Let's find out whether we are the right fit.

A first call is with an engineer, not a salesperson. Bring the problem; we will tell you honestly what we think.
