Services · Create

New products, designed and engineered to survive contact with real users.

Most new digital products fail on the things nobody scoped: the states between the happy paths, the content nobody wrote, the permissions model bolted on at the end. We design and build the whole system — including the unglamorous parts — so your first release can carry real users, real money and real scrutiny.

Problems we hear

If you recognise any of these, this is the right page

  • We have a strong idea but no shared definition of what the first release actually is.
  • We have designs, but nobody can tell us what they will cost to build or how long they will take.
  • Our last agency delivered screens, not a working product.
  • We need to show something credible to a board, an investor or a funder within a quarter.
  • We need the product to be accessible, secure and compliant from launch, not retrofitted.

Outcomes

What you should have at the end

A defined first release
A written, prioritised scope with explicit exclusions — so the conversation about cost is about facts rather than optimism.
A product in production
Deployed to a real environment on real infrastructure, with monitoring, backups and a rollback path from day one.
A design system you own
Tokens, components and usage rules, documented so a future team — ours or yours — can extend it without guessing.
Evidence for the next decision
Instrumented journeys and outcome measures, so the roadmap after launch is driven by usage rather than opinion.

Capabilities

What Create covers

Each of these is a distinct piece of work with its own deliverables. They combine into engagements rather than being sold separately.

01

Product strategy and discovery

Decide what to build, and what deliberately not to build, before spending on engineering.

The problem

Teams commit budget to a feature list before anyone has tested whether the underlying problem is real or whether the proposed solution addresses it.

What the work involves

We run structured discovery: stakeholder and user interviews, a review of the systems and data you already have, competitor and comparator analysis, and options modelling. We convert findings into a prioritised capability map split across MVP, Release 1 and Later, each with assumptions and evidence attached. Where evidence is thin we say so and propose the cheapest way to get it.

Typical deliverables

  • Discovery report with sourced findings
  • Prioritised capability map (MVP / Release 1 / Later)
  • Assumption and risk register
  • Costed delivery options with trade-offs
02

User research and service design

Understand the whole service, not just the screens.

The problem

Digital products frequently fail at the seams — the offline step, the call centre, the letter, the third-party handoff — which never appear in a wireframe.

What the work involves

We map the end-to-end service including the parts that are not software: the back-office process, the phone call, the paper form, the partner integration. We run interviews and usability testing with representative users, including users with access needs and low-bandwidth conditions where relevant to your audience.

Typical deliverables

  • Service blueprint covering front-stage and back-stage
  • User research findings with recordings and quotations
  • Journey maps with pain points and opportunities
  • Accessibility and inclusion findings
03

UX/UI and design systems

Interface design that specifies every state, not just the demo state.

The problem

Design handovers that cover only the ideal path force engineers to invent the loading, empty, error and permission-denied behaviour — inconsistently.

What the work involves

We design the full state matrix for every significant component, define the responsive behaviour from 320px upwards, and specify keyboard, focus and screen-reader behaviour. The output is a design system with tokens and documented components rather than a set of static frames.

Typical deliverables

  • Design system: tokens, components, usage rules
  • Full state coverage: loading, empty, populated, error, permission-denied
  • Responsive specifications across five breakpoints
  • Accessibility annotations to WCAG 2.2 AA
04

Corporate and product websites

Marketing sites that are fast, editable and actually convert.

The problem

Brand-led websites are often beautiful and unusable: slow, inaccessible, impossible for the marketing team to edit, and disconnected from the sales process.

What the work involves

We build content-managed sites on modern rendering architectures with performance budgets enforced in CI. Content editors get structured editing with draft, review and publish states. Conversion paths connect to your CRM so enquiries are routed and measured rather than emailed into a shared inbox.

Typical deliverables

  • Content-managed site with editorial workflow
  • Performance budgets enforced in the build pipeline
  • Structured data, metadata and redirect management
  • CRM-connected conversion paths with analytics
05

SaaS, portals, marketplaces and platforms

Multi-tenant, authenticated products where isolation and permissions are the hard part.

The problem

The difficulty in a platform is rarely the feature list. It is tenancy, permissions, billing edge cases, and making sure one customer can never see another customer’s data through any route.

What the work involves

We design the tenancy and permission model first and enforce it in the database as well as the interface, so a bug in the application layer cannot become a data breach. We test isolation positively and negatively for every role, across the API, search, exports, realtime channels, file storage and error messages.

Typical deliverables

  • Tenancy and permission model with a written role matrix
  • Database-level access policies with automated positive and negative tests
  • Billing, subscription and entitlement handling
  • Admin, moderation and support tooling
06

Native and cross-platform mobile apps

Apps built for real devices, real networks and real store review.

The problem

Mobile projects underestimate the operational surface: store review, privacy disclosures, device fragmentation, offline behaviour and release management.

What the work involves

We choose native or cross-platform based on your actual requirements — hardware access, performance profile, team composition, release cadence — and say why. We build for intermittent connectivity where your users need it, and we handle the store submission process including data-safety disclosures and account-deletion requirements.

Typical deliverables

  • iOS and Android applications with automated build and release pipelines
  • Offline and low-bandwidth behaviour where the audience requires it
  • Store listings, privacy disclosures and data-safety declarations
  • Crash reporting, analytics and staged rollout configuration

Engagement models

How we can work together

Fixed-price discovery

A defined discovery engagement with a fixed fee and a fixed set of outputs. It exists to make the next decision affordable and well-informed.

Best for: A new idea where scope and cost are genuinely unknown.

Fixed-scope milestones

Delivery broken into milestones with agreed acceptance criteria and payment on acceptance. Change is handled through a written change-request process.

Best for: A well-defined first release following discovery, with procurement that needs certainty.

Dedicated squad

A cross-functional team assigned to you for a fixed period at a fixed monthly rate, working to a prioritised backlog you control.

Best for: Continuing product development where priorities will legitimately change.

Delivery process

How the work runs

  1. 01

    Explore

    Frame the problem and agree whether we are the right team.

  2. 02

    Shape

    Paid discovery producing scope, architecture and a costed plan.

  3. 03

    Design

    Flows, states, content and a design system, tested with users.

  4. 04

    Build

    Two-week increments, each demonstrable and deployable.

  5. 05

    Validate

    UAT, accessibility, performance and security evidence.

  6. 06

    Launch

    Rehearsed cutover, monitoring, training and hypercare.

Technology approach

What we build with, and why

Web
TypeScript throughout. React with a server-first rendering model (Next.js App Router or equivalent), chosen for cacheability and time-to-first-byte rather than fashion.
Mobile
Swift and Kotlin where hardware access or performance demands it; React Native or Flutter where a shared codebase genuinely reduces total cost. We record the reasoning in an ADR.
Backend and data
Postgres by default. Managed services over self-hosted unless there is a specific reason. Event-driven patterns only where the coupling cost is justified.
Hosting
Vercel, Azure, AWS or Google Cloud, selected against your existing estate, data-residency requirements and the team who will own it after us.

Security and quality

Non-negotiables

  • Accessibility is designed in against WCAG 2.2 AA and tested with a keyboard and a screen reader, not only an automated scanner.
  • Performance budgets are agreed at design time and enforced in the build pipeline, so regressions fail the build rather than the launch.
  • Every significant module ships with loading, empty, error, permission-denied and success states.
  • Security review happens during design, not as a pre-launch gate that nobody has time to act on.
  • Anything we cannot verify does not get published as a claim.

Investment

Starting points

Indicative bands, not quotations. What moves a project within — or outside — these ranges is scope, integration count, data quality and regulatory context.

Idea Clarity Workshop

£1,500 – £3,500

A focused session that produces a Project Canvas and a delivery recommendation.

Product Discovery Sprint

£6,000 – £12,000

Two to four weeks of evidence-gathering, scope definition and costed options.

Focused MVP

£35,000 – £75,000

A first release built to production standard, typically 8–16 weeks.

Authenticated platform

£50,000 – £150,000+

Multi-tenant products with roles, permissions, billing and admin tooling.

All published figures are indicative and exclude tax, cloud and model usage, third-party licences and app-store fees. A price becomes an offer only when a person at NELLA Labs confirms it in writing.

Frequently asked questions

Can you give a fixed price before discovery?

Rarely, and we would be doing you a disservice if we did. A fixed price quoted against an unexamined brief is either padded to cover our risk or accurate only until the first real requirement surfaces. We quote discovery fixed, then quote delivery fixed against the scope discovery produced. If your procurement genuinely requires a single fixed figure up front, tell us and we will discuss how to structure it honestly.

Who owns the code and the designs?

You own the bespoke deliverables built for you — source code, designs and documentation — on payment. We retain ownership of pre-existing frameworks, reusable components and accelerators we bring with us, and grant you a perpetual licence to use them within the delivered product. This is written into the contract rather than assumed.

What if we already have designs?

We will review them and tell you honestly what is buildable as drawn and what is missing — usually the state coverage, the responsive behaviour and the accessibility specification. Sometimes the right answer is to build from what you have; sometimes it is to keep the visual direction and rebuild the specification underneath it.

How do you handle changes to scope during a fixed-scope project?

Through a written change request that states the scope, timeline and cost impact, which you approve or decline before we act on it. Changes appear in your client portal with their impact visible. We do not absorb changes silently and then discover a schedule problem later.

Will we be able to maintain this after you leave?

That is an explicit design goal. We use mainstream technology, document architecture decisions with their reasoning, write runbooks, and run a handover with your team. If you would rather we kept running it, that is what the Operate service is for — but it should be a choice, not a dependency we engineered.
