Who You Work with on Your Software Project

Cardiff founders, product managers and CTOs in the startup and scale-up scene work with a small named team. Here is how that relationship runs from week to week.

Your Lead, Your Contact

One person leads your project and picks up when you ring. QA specialists, UX designers and engineers back that lead up, so a scale-up in Cardiff gets extra hands without a long recruitment drive.

Communication You Can Follow

We can meet over video, or face to face if you arrange it. Between meetings you get brief written notes on what was decided, what changed and what we are waiting on, so no one has to rely on recall.

Alongside Your Developers

Your product owner, IT team, in-house developers and current supplier all stay in the picture. Good documentation and an orderly handover leave your own staff firmly in charge.

Build, Buy or Modernise? A Plain-English Guide

Custom code is only one option, and sometimes the wrong one. We walk Cardiff clients through four routes before recommending any.
Route

Buy Off the Shelf

Selection advice and integration
Pick it when
Your workflow is common enough that staff can bend to the product.
Trade-off
Limited fit and ongoing licence costs.
Route

Configure a Platform

Configuration and extensions
Pick it when
A platform covers the bulk of it and you need a few changes.
Trade-off
Platform limits and vendor dependence.
Route

Build Custom

Full custom build
Pick it when
How you work sets you apart, or no product on the shelf matches it.
Trade-off
Takes more work at the start, but the direction is yours.
Route

Modernise What You Have

Application modernisation
Pick it when
The software still runs, yet it drags, exposes risk or resists every change.
Trade-off
An audit comes first, and delivery usually runs in stages.
Unsure where you land? A brief discovery session normally makes the choice clear.

Security and Quality Checks Built Into Every Build

Our practices take their lead from the NCSC’s eight secure development principles. Day to day, these are the habits that show it.

What Shapes the Cost of Custom Software

Price depends on scope and risk, which is why we leave figures off this page. Six things move the cost most, and one call settles each of them.

Scope and Users

↑ Costs more when
investors, clients and staff each need distinct roles and views
↓ Costs less when
one core workflow makes up a lean first release

Integrations

↑ Costs more when
it connects to banking, lab or legacy records systems
↓ Costs less when
the systems you connect publish clear API documentation

Data Migration

↑ Costs more when
years of records across spreadsheets and old databases move over
↓ Costs less when
only a small, clean set of records moves across

Architecture

↑ Costs more when
it processes events in real time or serves many tenants
↓ Costs less when
demand stays light and the design stays plain

Security and Compliance

↑ Costs more when
it handles financial, medical or security data under audit
↓ Costs less when
only low-risk data stays inside the business

Support After Launch

↑ Costs more when
you need monitoring around the clock with fast response
↓ Costs less when
office-hours cover will do

Hire Software Developers

Choose by your stage. A startup’s first release suits a fixed price build, a scale-up adding capacity suits dedicated developers, and a business replacing an old system suits time and material.

Fixed Price Build

Everything is priced and scheduled up front. Good when the brief and budget are settled.
Suits

Time and Material

You are billed for time spent, and you reorder priorities every sprint. Fits products that are still taking shape.
Suits

Dedicated Developers

An embedded group of developers, with QA and design support as needed, using your sprint rhythm and tooling. Made for long roadmaps.

How to Choose a Software Development Company

Proposals on paper are hard to tell apart. These seven questions show how a team behaves after kickoff.
01

What Will Be in My Hands at Handover?

Listen for
The code itself, written guides, environments and deployment steps
02

Who Owns the Intellectual Property?

Listen for
You do, with ownership written into your contract.
03

Who Exactly Will Be Writing Code for Us?

Listen for
Named people with stated roles, not a general mention of the team.
04

What If a Previous Supplier Left the Build Half Done?

Listen for
We audit the code and designs, report what is sound and agree a recovery plan in writing before any new work starts.
05

How Do You Test and Release?

Listen for
Automated testing, a staging site and a way to roll back
06

Are You Able to Work Alongside Our Product Owner and Developers?

Listen for
Yes. Expect shared tooling, attendance at your stand-ups, priorities set by your product owner and code reviews that both sides can see.
07

Will You Advise Against Building?

Listen for
Yes, and the alternative of buying or configuring gets a fair hearing

How We Run a Software Project

There are six stages, and each leaves you with something to review. How long they take depends on the size of the job.
01

Discovery

Around a week of workshops on users, workflows and constraints.
02

Scoping and Architecture

One to two weeks to deliver a written scope, technical approach and quote.
03

Design and Prototype

About two weeks to create clickable screens real users can test.
04

Sprint Builds

Work runs in short sprints, and every one finishes by showing you working software.
05

Evaluation and QA

Testing takes around four weeks and checks that features work, performance holds up and security stands firm.
06

Launch and Iterate

We release, monitor the live system and plan what to improve next.
Each stage ends with something you can review.

The Villas Mooloolaba

Hospitality / Boutique Vacation Rental
The Villas Mooloolaba does the hard part well – four unique two-bedroom villas around a shared pool on Queensland’s Sunshine Coast. The website wasn’t carrying its weight: competing against hotel chains and OTA listings meant direct booking had to feel just as easy, and guests couldn’t easily compare all four villas.
