Follow one customer

One customer, from trial to renewal.

Pick a step to see the parts of a SaaS that customers never notice until they break.

Customer lifecycle

Step 1 of 4

They sign up

A new workspace is created in seconds, with their data kept separate from everyone else's.

  • They sign up
  • The team joins
  • They pay
  • You support them

Signs you need us

When your product needs a real platform.

Sound familiar? Book a call
  1. 01

    Customers need their own workspace

    A single shared login or database no longer works.

  2. 02

    Billing is done by hand

    Invoices and plan changes eat into your week.

  3. 03

    Support needs an engineer

    Simple customer questions turn into database lookups.

  4. 04

    Larger clients ask hard questions

    Roles, audit logs and security reviews start blocking deals.

  5. 05

    Your prototype will not stretch

    What worked for ten users slows down at a hundred.

What we build

The parts every SaaS needs.

Cheap to build early, expensive to add later.

Which start fits?

SaaS starter kit or a custom build?

A starter kit can save weeks if your product fits its assumptions.

How we work

From first version to a SaaS that scales.

Six steps, the same on every project. AI-assisted workflows speed up the build, an engineer reviews every change, and at each step there’s something you can check for yourself.

Security built in from the first sprint, not added at the end.

“Good software takes work off your plate. We build what you need, show you as we go, and tell you straight when something isn’t worth building.”
Ali Raza, Co Founder

  1. Step 01

    Discovery and scope

    We start with what you are really building, not just a list of features. Goals, users, limits and edge cases are agreed before anyone writes code.

    Scope agreed before we build

    A written scope and milestone plan for you to approve.

  2. Step 02

    Architecture and planning

    We map the system before the build: how the parts connect, where the data goes and which APIs it needs. Fewer surprises, and no big rewrites halfway through.

    A plan you can read

    The architecture and milestones, in plain words.

  3. Step 03

    Build in short sprints

    We work in short cycles with something usable at the end of each one. You see progress the whole way, so problems get fixed while they are small.

    Working software, not status reports

    Real features you can try at each milestone.

  4. Step 04

    Testing

    Every release is tested the way people will really use it. Integration bugs and slow spots show up before your users find them.

    Releases you can trust

    Test plans and automated checks on every release.

  5. Step 05

    Release

    Only stable builds go live. We release step by step, so a problem is caught early and can be rolled back quickly.

    You own what we build

    The code, cloud and app store accounts are yours.

  6. Step 06

    Handover or keep building

    Once it is live, you choose: a full handover with documentation, or we keep building with the same team and the same rhythm.

    We stay after launch

    Support and new features, or a documented handover.

Before you commit

Know what to build first.

Tell us about your product and customers. We will tell you what can wait.
