Everything a startup needs, in the order it actually needs it

Five engagements, each shaped for a different moment in a product's life. Most founders start with one and grow into the next — nobody gets sold the whole ladder on day one.

Discovery & Product Definition

The cheapest phase of any startup is the one before the first line of code — and the one founders are most tempted to skip. We turn a described idea into a defined product: what it does, who it is for, what result would prove it works, and what it will take to build. You leave with a plan you could hand to any competent team, including one that is not us.

  • Hypothesis and success metricThe one number that tells you whether to keep going
  • Scope — and the cut listWhat ships first, what waits, and the reasoning behind both
  • System architectureData model, stack choice, and the integrations you cannot avoid
  • Clickable prototypeSomething real to put in front of users and investors

MVP Development

An MVP is not a smaller version of the finished product. It is the shortest honest route to finding out whether anyone wants it. We build one core loop, wire analytics in from the first commit, and put it in front of real users in production — not behind a staging link and a demo call.

Everything that turns a product into a business — billing, permissions, admin tooling — waits until there is evidence the product itself works. That restraint is the point, and it is usually the part founders thank us for later.

Build an MVP
In the first release
  • The core user journey, end to end
  • Only the authentication you actually need
  • Product analytics, wired in from day one
  • A real production deployment
  • A channel to collect what users tell you
Deliberately deferred
  • Billing and subscriptions
  • Roles, permissions, teams
  • Admin panels and back-office tools
  • A second platform
  • Optimisation for traffic you do not have
When payments belong in the MVP after all

If your hypothesis is that people will pay — a subscription app, a paid-from-day-one SaaS — then the paywall is the experiment, and shipping without it proves nothing. We establish which case you are in during discovery, before a single sprint is planned.

Scale-Up Engineering

Users showed up and the metric moved. Now the product has to become a business: take money, support teams, survive a traffic spike, and — the part that quietly decides everything — keep shipping changes without breaking what already works. This is a continuous engagement rather than a project with an end date; we work as your product team.

  • Payments, subscriptions, billingStripe, StoreKit, Google Billing, RevenueCat — plus the pricing logic behind them
  • Roles, permissions, admin toolingTeam accounts, back-office, support tooling your operators can use
  • Integrations and APIsPublic APIs, webhooks, and the third-party services your customers ask for
  • Reliability and deliveryPerformance work, monitoring, a test suite that earns its keep, and a release nobody has to brace for

Rescue & Rebuild

An agency went quiet mid-project. A technical co-founder left. An MVP that was never meant to outlive its own experiment is now carrying paying customers, and every release is a held breath. We take over codebases we did not write: first making them safe to operate, then rebuilding only the parts genuinely standing between you and your next release.

  • Audit firstAn honest read on the code, the infrastructure, and what it will cost to keep
  • Stabilise before refactoringCrashes, outages and data loss first; tests around what must not break; architecture last
  • Rebuild incrementallyMigrations that ship in pieces, with the product live throughout
  • Documented handoverIf you are hiring in-house, we hand over something a new team can actually run

Fractional CTO & Tech Due Diligence

Some decisions are too expensive to get wrong and too rare to justify a full-time hire — choosing a stack, judging a vendor's proposal, deciding whether to rebuild, hiring your first engineers. We bring that judgement in part-time, and run the same review for investors sizing up a target.

  • Technical strategy and roadmapSequencing the build so it matches your funding and hiring plan
  • Due diligenceCode, architecture, and delivery risk — written up plainly, for founders or investors
  • Hiring and team setupRole definitions, technical interviews, and onboarding your first engineers
  • Architecture reviewA second opinion before you commit to a decision that is hard to reverse

How we build

How fast can you change your mind?

It is the question that decides whether a startup survives its own learning. Testing a hypothesis is only as fast as fixing the thing you tested it with — so every engagement above rests on the same engineering habits, whatever the stage.

Tests where they pay for themselves

Not a coverage number to put in a report. Tests on the paths that would cost you customers if they quietly broke — so today's change does not become next week's incident, and nobody is afraid to touch the code.

A deploy nobody dreads

One command, automatic rollback, and a release you can run without booking a meeting about it first. Fear of deploying is the most expensive tax a small team pays, and it compounds quietly.

A build you can click every week

Weekly demos on something real, not a slide about progress. Your feedback lands while it is still cheap to act on, instead of arriving when everything is already built around the wrong assumption.

Technology

The stack is a means, not a menu

We pick technology to fit the product and the team that will inherit it — not the other way round. Here is what we work in most.

Mobile

Swift, Kotlin, React Native. App Store and Google Play submission and release management.

Web

React, Next.js, TypeScript. Dashboards, SaaS front-ends, and marketing sites that load fast.

Backend

Node.js, Python, Go. PostgreSQL, Redis, REST and GraphQL APIs with auth and rate limiting.

Delivery & testing

AWS, GCP, Docker, GitHub Actions. Automated test suites, staged rollouts, and alerting someone actually reads.

Payments

Stripe, StoreKit 2, Google Billing, RevenueCat — subscriptions, trials, and the edge cases behind them.

Analytics

Amplitude, Mixpanel, PostHog. Funnels, retention cohorts, and experiments you can act on.

Not sure which one you need?
