Collaborative Product Development.

Sometimes you don't need to outsource a product. You need the right expertise inside the team that's already building it.

Arch works collaboratively with in-house product and technology teams, adding specialist capability where and when it's needed. We can strengthen development capacity, bring in UX expertise, help untangle an established codebase, tackle a critical product challenge or provide a multidisciplinary team around a particular phase of delivery.

This isn't about handing over a brief and waiting for the result. And it isn't body shopping.

Our people become part of the way your team works. We share environments, priorities and objectives, bringing an external perspective while staying close enough to your organisation to make informed decisions quickly.

You keep the context. We bring the additional firepower.

We've worked alongside established product, design and engineering teams across organisations of different sizes and sectors.

With Nimbus Disability, that has meant understanding and evolving a complex ecosystem of interconnected, business-critical technology alongside its existing developers.

For BoilerJuice, our developers worked closely with an established product manager, designer and QA team to deliver a new mobile experience integrated with its existing infrastructure.

And for Super Benji, a focused two-week collaboration gave its development team a set of prioritised, development-ready UX improvements without interrupting the wider product roadmap.

Different teams need different things from an external partner. That's the point.

What is collaborative product development?

Collaborative product development is an approach where external product, design or engineering specialists work directly alongside an organisation's existing team rather than delivering a project entirely separately.

Arch can add specific expertise or broader product capability while working within existing roadmaps, workflows and technology environments.

Is this the same as staff augmentation?

No. Our approach isn't based on supplying developers to fill individual roles.

Arch brings the wider capability and experience of a digital product studio into the engagement. Depending on the challenge, that can include product strategy, UX/UI, frontend and backend engineering, mobile development and specialist technical expertise.

Can Arch work with our existing developers?

Yes. We regularly collaborate directly with existing development, product, design and QA teams.

We can work within established development environments and delivery processes, helping increase capacity or bring specialist expertise to particular parts of the roadmap.

Can you work on an existing product or codebase?

Yes. You don't need to be starting a new product.

We can work with established products, including complex and long-running systems. We begin by understanding the existing technology, dependencies and business context before recommending significant changes.

Can Arch provide UX or design support to our development team?

Yes. Specialist UX and UI support can be provided as part of a wider engagement or around a specific challenge.

For Super Benji, Arch delivered an intensive two-week collaborative UX sprint that resulted in development-ready designs for its existing developers.

Do you offer short-term product or development support?

Yes. The engagement can be shaped around the problem.

That could mean a focused sprint around a defined UX or technical challenge, additional capability during a critical delivery phase, or an ongoing partnership supporting a longer product roadmap.

Can you help upskill our internal team?

Yes. Because our teams work collaboratively, knowledge transfer can be built directly into delivery.

Where developing a particular internal capability is important, we can place additional emphasis on documentation, shared working, technical knowledge transfer and practical upskilling.

Why work with Arch alongside an internal team?

Arch has been designing and developing digital products since 2005, giving organisations access to experience across product strategy, UX/UI, mobile and web development, backend engineering and emerging technology.

Rather than simply adding headcount, we bring additional perspectives and specialist capability to the team you already have, helping you move faster while keeping the product knowledge and expertise inside your organisation.
