Custom Software Development
We help funded teams move from roadmap to reality with embedded product teams and delivery leadership that scales with you.
Who is this for?
You have the idea. The backing. The urgency.
But no internal team — or no time to lead one.
You’re expected to deliver a working product. But too often you’re stuck managing contractors, writing specs or firefighting delivery issues that shouldn’t be yours.
We help companies like yours move from roadmap to reality — with structure, speed, and software that’s built to evolve.
What we deliver in software
MVPs that Create Traction
We guide founders and product leaders from sketch to stable MVP — quickly. Our early-stage work blends lean delivery with production-ready architecture, designed to validate with users, impress investors, and support structured growth.
Cross-Platform Digital Experiences
We build polished, responsive platforms that work across devices and roles. From onboarding flows to admin tools, our design and engineering teams prioritise clarity, usability, and performance — across web and mobile.
Smart Integrations & Workflow Automation
We integrate what matters — whether that’s CRMs, payment providers, ID checks, or internal APIs. We design platforms with future integrations in mind, using modular, API-first approaches that reduce friction and unlock scale.
AI & Data-Driven Features
We enable smart functionality — not just model outputs. Our team delivers real-time analytics, AI-assisted interfaces, and machine learning integrations that enhance decision-making and automate workflows across sectors.
Embedded, Flexible Delivery Teams
Our teams feel like your own — whether we’re self-managed or working under your leadership. From engineering and QA to UX and product strategy, we scale with your roadmap, risk profile, and hiring gaps.
Quality, Compliance & Confidence
Performance, accessibility, and auditability are built into our process — not patched later. We embed QA, documentation, and compliance thinking from day one, ensuring every release meets your standards and your sector’s.

The Preux Product Development Lifecycle
1. Discovery & Scoping
2–3 weeks
We begin with alignment. Through collaborative workshops and technical mapping, we define your platform’s purpose, scope, user roles, and delivery risks. Whether you’re planning multilingual publishing tools, HIPAA-compliant workflows, PCI DSS-ready fintech platforms, or investor-facing dashboards, we bring clarity to complexity and turn goals into a structured delivery plan.
Architecture & UX Design
2–4 weeks
We design for the real world — for clinicians, editors, traders, and internal operators alike. This phase covers system architecture, wireframes, and user journey mapping. We create intuitive flows that respect regulatory context — from FCA-aligned UX and GDPR-conscious design to role-based permissions and localisation. The outcome: clickable prototypes and documentation that’s ready for build.
3. Core Build (MVP or V1)
2–4 months
With clear scope and structure, we execute fast—but without cutting corners. Using proven frameworks and optionally low-code tools, we deliver your first usable product with working authentication, core workflows, and clean UI aligned to your brand and user context. From clinician portals to media templates or financial dashboards, we launch real products, not static prototypes. Built for real users, not just investor decks.
4. Iterative Rollouts & Feedback Loops
Ongoing (monthly sprints)
We launch, learn, and refine. Once live, our embedded teams work in agile sprints — continuously improving based on user feedback, platform data, and evolving compliance. This phase often sees features like multi-role access, content tooling, payments, permissions, KYC/AML processes, analytics, and syndication logic come to life. Every release is designed to move the product forward without compromising system stability.
5. Growth & Scale Support
3–6+ months
We adapt as you grow. Whether that means scaling cloud infrastructure, adding integrations (like EHRs, CDNs, or analytics platforms), or phasing in QA, DevOps, and business analysts, we adjust the team to match your stage — not the other way around.
6. Long-Term Partnership & Innovation
Ongoing
Preux often becomes a long-term product partner, not just a delivery vendor. We embed with your team to support roadmaps, technical strategy, and innovation. Whether you’re expanding across regions, investor milestones, or user types — we stay aligned, stay consistent, and stay accountable.

We specialise in complex, multi-user platforms — often with compliance, custom flows, and deep integrations. That includes marketplaces, admin portals, onboarding flows, SaaS dashboards, workflow automation, and AI-enabled features. Everything we build is structured for scale, not just speed.
There are three primary ways to work with Preux:
We can deliver a full build on our infrastructure (Custom Software)
Embed a remote team into your organisation (Embedded Teams)
Or support you with strategic input (Advisory).
We help you choose the right structure based on your goals, stage, and internal capabilities.
We often begin before the brief is fully formed — helping you clarify what to build, in what order, and why. We shape the scope with you, prioritise features, design key flows, and guide you towards a structure that’s technically feasible and commercially valuable.
Every project is different, but most teams include engineers, a product manager, QA, and UX. For more complex builds, we may add DevOps, business analysts, or regulatory consultants. You won’t get anonymous contractors — you’ll meet and work with the people delivering.
Yes. We support early-stage founders launching MVPs, as well as growth-stage companies replacing underperforming delivery. We also work with established brands who need a trusted build partner for specific projects.
We do this often. Whether you need to augment with one or two key roles, or want a complete delivery squad to operate under your leadership, we adapt. Our teams integrate smoothly into your workflows, tools, and communication rhythms.
We start with a discovery and planning phase, clarifying scope, dependencies, and decision points. We don’t give artificial deadlines — we give structured plans, weekly visibility, and clearly phased delivery. Our goal is not just to move fast — but to move well.
Yes. We’ve delivered platforms with HIPAA, GDPR, and KYC requirements — including audit logs, access controls, encrypted data handling, and consent flows. We design infrastructure and user flows with compliance in mind from day one.
We usually work on fixed monthly rates per role. You get experienced people, hand-picked for your project, working full-time or part-time. Transparent. Predictable. Aligned. There are cases where we offer a fixed price or other structures, though it can demand a longer stage of planning and roadmapping.
You can continue building with us long-term, bring some roles in-house, or retain us for strategic oversight. We’re not locked into a single model — we adapt as your product and team evolve.
