THE FOUNDATION BENEATH IT

Scope the first version. Keep a path to the next.

A useful product.
A deliberate scope.

An MVP should solve a real problem from beginning to end. Separate what delivers that outcome from what can wait for evidence.

BUILD THE CORE

What lets a customer succeed?

Define the smallest complete journey that delivers the product’s main value.

  • One clear audience and problem
  • The essential user workflow
  • Appropriate access and data controls
  • A way to collect useful feedback
EARN THE NEXT RELEASE

What can real use help decide?

Keep a visible backlog without turning every future possibility into a launch requirement.

  • Additional personas and use cases
  • Advanced reporting and customisation
  • More integrations and pricing tiers
  • Expansion based on actual demand

The platform behind the product.

These are design decisions to make together, not a feature list every SaaS needs. The first release should include the foundations your business model actually requires.

Accounts & access

Sign-up, authentication, onboarding and roles matched to the way people use the product.

Teams & workspaces

Organisation structures and data boundaries where the product serves multiple customer teams.

Subscriptions & billing

Payment integration, plans and subscription lifecycle handling where your commercial model needs them.

Admin & support tools

The operational controls your team needs to help customers and manage the service.

Data & reliability

Appropriate storage, backups, monitoring and performance considerations for the agreed requirements.

Integrations & APIs

Connect external services without losing sight of access, vendor costs and failure handling.

From access to the business behind it.

Delivered platforms with gated experiences, payments and operational workflows — useful building blocks when planning a SaaS product.

Have a question specific to your project? Let’s talk it through.

Tell us about your project
01Can you help if we only have an idea?

Yes. We can start by clarifying the audience, problem and core workflow, then use discovery and prototyping to define a buildable first release. Customer demand and product-market fit still need to be validated with your audience.

02Can you take over an existing SaaS product?

We can assess the codebase, architecture, hosting and product backlog before proposing changes. The review helps identify technical constraints and whether incremental improvements are practical.

03Do you build subscriptions and multi-tenant platforms?

We can include subscriptions, teams and tenant-aware data access where required. Billing rules, permissions, isolation requirements and plan changes need to be designed explicitly rather than assumed.

04How do you keep an MVP within budget?

We agree the core user outcome, prioritise features and define acceptance criteria before development. New requirements are assessed against the agreed scope, budget and release priorities.

05Will the product scale as we grow?

Architecture should reflect expected usage and realistic growth scenarios. We can plan monitoring, performance testing and capacity changes, but no architecture removes every future scaling decision or cost.

06Who owns the product and source code?

Ownership, source-code access, intellectual property and third-party licences are defined in the project agreement. We also agree hosting access, documentation and responsibilities after launch.

Where is your product today?

An idea, a prototype or an existing platform — we’ll start from the stage you’re at.
