Service
SaaS Product Development
Building a product other businesses pay to use — and the operational groundwork that makes that sustainable.
What this service is
SaaS product development is building software delivered to many customers from shared infrastructure. What separates it from a one-off application is everything around the features: tenant isolation, self-service onboarding, subscription billing, per-tenant configuration, usage metering, and the ability to ship updates without coordinating with every customer.
The problem
What usually brings people here
A successful project, asked for by others
You built something internally or for one client, and other businesses now want it. Turning that into a product is a different engineering problem.
Tenancy decided too late
Retrofitting tenant isolation onto a single-customer application is one of the most expensive mistakes in this category.
Onboarding that needs you
Every new customer requires manual setup, so growth is capped by your own calendar.
No usage visibility
You cannot see which accounts are active or what they use, so you can neither price nor support the product well.
Capabilities
What we do
- Multi-tenant architecture and tenant isolation
- Authentication, roles and organisation management
- Subscription billing and payment integration
- Self-service onboarding and provisioning
- Usage metering and analytics
- API design for customer integrations

Use cases
Typical engagements
Productising internal software
Taking a system built for one business and turning it into something several can use safely and separately.
A new product from scratch
Architecture, build and launch groundwork for a first version aimed at real paying customers rather than a demo.
Scaling an early product
An existing SaaS straining under customer growth, needing isolation, performance and operability work.
Delivery
How the work runs
- 01
Discovery & requirements
We map how the work actually flows today — the systems, the spreadsheets, the manual handoffs — and agree what success looks like in measurable terms.
- 02
Solution architecture
Data model, service boundaries, integration points and hosting. You get the shape of the system before anyone writes production code.
- 03
UX & technical design
Screens and flows for the people who will use it daily, reviewed against the architecture so the design is buildable as drawn.
- 04
Development & integration
Built in increments you can see and use. Integrations are wired early, because that is where most projects actually go wrong.
- 05
Testing & quality assurance
Automated tests around the logic that matters, plus migration rehearsals against real data shapes before anything goes near production.
- 06
Deployment & onboarding
Release pipeline, environment configuration, data migration and training for the teams who have to live with the system.
- 07
Support & continuous improvement
Monitoring, fixes and the next increment. Software that is used changes; the engagement allows for that.

Before you commit
What to weigh up
Decide the tenancy model early — shared schema, schema per tenant, or database per tenant — because changing it later touches everything. Build the operational surface alongside the features: without usage data and support tooling, you cannot run the product even if it works.
Questions
Frequently asked
- What architecture should a new SaaS use?
- It depends on the isolation your customers require and the data volumes expected. Shared-schema is cheapest and scales furthest; database-per-tenant gives the strongest isolation and the heaviest operational load. The decision belongs in week one, not month six.
- Can you turn our internal system into a product?
- Often, yes. The work is usually tenancy, onboarding, billing and configurability rather than the core features, which already exist. We assess what carries over before proposing a path.
- Do you handle billing integration?
- Yes — subscription plans, trials, upgrades and the webhook handling that keeps billing state and application state consistent, which is where most implementations break.
- How do you approach a first version?
- Narrow the scope to the workflow that justifies the purchase, build that properly, and launch to real users. Breadth added before anyone has paid is usually breadth built on a guess.
Our own products
Software we built on this
AI Interview Platform
Structured, evidence-based hiring decisions — without handing the decision to a model.
AI Demo Agent
Every interested prospect sees a real demo the same day, without waiting for a solutions engineer.
We use this capability on our own products, not only on client work. If one of them already does what you need, it will be cheaper than building it.

Software built around how your business actually works, rather than bending the business to fit a package.
Cloud & DevOps
Deployment pipelines, infrastructure and observability so releases are routine rather than an event.
API & System Integration
Connecting the systems you already run so data moves between them reliably instead of by spreadsheet.
