You know what the software should do. We build it so you can sell it.

We're a customized software development company for domain experts with validated concepts — logistics, finance, construction, healthcare, legal, manufacturing. You've spent years seeing the gap no SaaS product fills. We take that knowledge and build it into a commercialisation-ready product with production architecture, multi-user backend, and billing your customers can actually use. If you're building a SaaS company from scratch, see our SaaS development service instead.

The domain expert with a product to build.

5–20 years in an industry where the software that exists is built for the average case — and your case isn't average. You've seen the gap. You've validated the concept, possibly prototyped with AI tools. Now you need a technical partner to build it into something you can sell or license to other businesses in your industry.

This is not for founders who haven't built anything yet — that's the SaaS development service. This is for people who know their industry's problem better than any developer ever will, and want a technical partner who can take that knowledge and build it into software they can actually sell.

Already committed

Validated the concept, invested time prototyping. No 'should we build this?' conversation needed.

Understands the problem deeply

Faster discovery, clearer scope. Domain experts produce better specs than funded founders without industry experience.

Commercial model is clear

Building to sell or license. The buyer, the pricing logic, and the value proposition are already defined.

Can evaluate quality

Recognises a thoughtful architecture proposal. Knows when a technical decision doesn't make sense for their domain.

Short engagement cycle

The Phase 1 assessment produces a fixed-price proposal. Most clients move directly from assessment to build.

Industries where domain experts identify the gaps.

The pattern is consistent: a specialist in a specific industry sees a workflow, a calculation, or a decision process that no horizontal SaaS product handles correctly for their context. These are the sectors we see it most often.

Logistics & Supply Chain

Route optimisation, load planning, carrier selection, and freight visibility tools that no generic TMS handles for specialised freight types.

Finance & Lending

Custom underwriting workflows, deal structuring tools, and portfolio management systems for lenders whose criteria don't fit off-the-shelf platforms.

Construction & Real Estate

Estimating, project costing, subcontractor management, and compliance tools built around how specific construction types actually work.

Healthcare & Clinical

Practice management, clinical workflow, and patient engagement tools for specialised practices where generic EMR platforms add friction rather than remove it.

Legal & Compliance

Matter management, document automation, and compliance tracking systems for practices or compliance functions with non-standard workflows.

Manufacturing & Operations

Job costing, quality management, production scheduling, and supplier tracking tools built for specific manufacturing processes and materials.

If your industry isn't listed, the same pattern applies — we've worked with domain experts across other verticals. The question is whether the software gap you've identified is specific enough to your sector that no existing tool will ever fill it correctly.

What's missing between a working prototype and a sellable product.

AI coding tools — Loveable, Bolt.new, Cursor, v0 — have lowered the barrier to validation, not to building a sellable product. A prototype built with these tools typically has six critical gaps. Every one of them has to be solved before a customer can use it.

What a prototype has

What a sellable product needs

Data architecture

Single user, flat data structure — works for the builder, not for customer B's data next to customer A's

Multi-tenant schema with proper data isolation — each customer's data is completely separate

User management

One login, one session — no concept of teams, roles, or permissions

User accounts with roles (admin, manager, operator), invitations, and access control by feature

Module structure

Everything hardcoded — no way to enable/disable features per customer or per plan

Configurable modules tied to subscription tier or customer settings

Deployment

Runs on the builder's machine or a single cloud instance — no way to onboard another customer

Containerised, cloud-deployed, with dev/staging/production environments and CI/CD

Security

No input validation, no rate limiting, no secrets management — acceptable for a demo

CSRF protection, input sanitisation, rate limiting, encrypted secrets, dependency auditing

Billing and subscription

No billing — assumes free access or manual invoicing

Subscription or licence management integrated with Stripe or equivalent — automated billing from day one

Phase 1 maps exactly which of these gaps your prototype has — and what it would take to fill each one.

Book the Product Assessment

Built a prototype with AI tools but can't get it to production? The assessment takes 3–5 days.

Book an assessment

Two phases. The first one de-risks the second.

Every product build starts with a Product Feasibility Assessment. That assessment produces the fixed-scope specification for the build — no surprises, no scope creep, no hourly billing.

Product Feasibility Assessment

We review your concept or existing prototype, assess what needs to be built vs rebuilt, define the MVP scope, and produce an architecture document. You understand exactly what you're committing to before the build starts.

Duration3–5 business days

OutputFeasibility report + architecture spec + fixed-price proposal

ObligationNone — the spec is yours, whoever builds it

Product Build

Fixed-price build based on the Phase 1 specification. Production-grade architecture, multi-tenant, billing integrated, admin console included. Shipped in fortnightly releases — working software every two weeks.

Duration12–36 weeks depending on scope

PricingFixed-scope, priced from Phase 1 specification

BillingFixed scope — no hourly billing, no scope surprises

How an engagement works

Product Feasibility Assessment

3–5 days. We review your concept or prototype, define MVP scope, assess architecture requirements, and produce a written specification.

Fixed-price build proposal

The assessment output is a detailed fixed-price proposal. You know the full scope and timeline before committing to the build.

Phased build — fortnightly releases

Working software every two weeks. You see progress and can make informed decisions based on what you're seeing.

Commercialisation-ready deployment

Multi-tenant, billing integrated, admin console, production environments. Built to work for your fiftieth customer the same as your first.

Handoff and ongoing development

Full documentation, code walkthrough, IP transfer. Most clients continue with a monthly retainer — the team that built it keeps developing it.

Start the conversation

What every product build includes.

Every engagement covers what a product needs to be commercially viable — not a minimal build that requires a second round of work before you can onboard a customer.

Multi-tenant backend

Proper data isolation between customers
Database schema designed for a product, not a single user
Scalable from customer 1 to customer 100 without architecture changes

User management

Account creation, email verification, password management
Roles and permissions — admin, manager, operator
Team invitations and access control by feature or module

Module architecture

Features configurable by subscription tier or customer settings
Enable/disable modules per customer
Clean separation so new modules can be added without breaking existing ones

Billing and subscription

Stripe or equivalent — automated billing from day one
Subscription plans, free trials, and plan upgrades
Licence management for B2B licensing models

Deployment infrastructure

Containerised — Docker, cloud-deployed (AWS, GCP, Vercel, or Render)
Dev, staging, and production environments
CI/CD pipeline — automated testing and deployment

Admin console

Customer management dashboard
Usage monitoring and account controls
Support tooling — impersonate, reset, audit logs

What you get at handoff. And what happens next.

Most domain experts building a product have been burned once — by an agency that held the code hostage, by a developer who left and took the knowledge with them, by a system no one else understood. We structure every engagement so you're not dependent on us to keep the product running or developing.

If you want to continue with us after the build — most clients do — you have a team that already knows the codebase. If you want to bring the work in-house or move to another partner, you have everything you need to do that on day one of handoff.

Talk about your product

Full source code transfer

Every line of code, every configuration file, every migration script. Transferred to your repository on completion — not held by us.

Architecture documentation

How the system is structured, why key decisions were made, how to extend it. Written for a developer who's never seen it before.

Local development setup

Step-by-step instructions to run the full stack locally. Any developer you bring in can be productive within a day.

Code walkthrough session

A recorded session walking through the codebase, module by module. Reference material for whoever develops it next.

IP assignment in contract

Full intellectual property assignment is in the contract before any work begins. No licensing, no shared ownership.

Common questions about software product development.

A custom internal tool is built for your operation. A software product is built to sell — which means multi-user access, tenant separation, subscription or licensing logic, and a UX that works for customers who didn't design the system. The architecture is fundamentally different. We scope for commercialisation from the start.

Yes — but we'll audit it first. AI coding tools produce working demos, not production architecture. We review what you've built, identify what's salvageable and what needs rebuilding, and scope the work from there. Most prototypes share the same gaps: no proper data model, no multi-user design, no deployment path. We've seen all of them.

The Product Feasibility Assessment is 3–5 days. A focused MVP — core feature set, one user type, basic subscription — is 12–20 weeks. A full product with multiple modules, user roles, and admin infrastructure is 24–36 weeks.

We push back when the spec won't work. Domain experts know the problem better than any developer. We know what makes software scalable, maintainable, and deployable at cost. The best outcomes come from that combination. We're not a ticket factory.

Multi-tenant architecture (each customer's data is isolated), subscription or licensing billing, user management with roles and permissions, an admin console you can use to support customers, and deployment you control. The product should work for your first customer the same day it works for your fiftieth.

Phase 1 tells you. We assess what to build on and what to rebuild from scratch. You make that decision before committing to Phase 2. If the prototype has core logic worth preserving, we preserve it. If it's scaffolding only, we say so.

No. You bring the domain knowledge. We bring the architecture. Discovery is a conversation, not a technical interview. The best products we've built came from domain experts who could describe the problem in depth — not from people who already knew what stack to use.

Not fundamentally — but it shapes the architecture. Licensed products often need on-premise deployment options, audit exports, and integration with the buyer's existing systems. We design for your go-to-market model in the first scoping call.
