Our product design process for London businesses

Here’s how we help ambitious London businesses turn early-stage ideas into market-ready products, with clear commercial direction from day one.

Commercial alignment

Before we sketch a single concept, we take the time to understand your business, your market, and what success actually looks like. This means defining your commercial objectives and long-term vision alongside the functional aspects of the product itself.

This commercial alignment is fundamental to our process, helping us spot opportunities, focus design direction, and speed up decision-making.

Design, development & detail

Next, we develop concepts with commercial viability front of mind, including target cost, assembly approach, and manufacturing constraints.

These concepts are then refined into manufacturable product designs. Our engineering team resolve technical challenges as they arise, ensuring each design is fully buildable without compromising the features that give your product its competitive edge.

Delivery

The final phase focuses on taking your product seamlessly into production.

We remain involved beyond design delivery to support real-world implementation. This includes helping select manufacturing partners, overseeing prototype development, and resolving production challenges so your product successfully reaches the production line.

FAQs

Are we able to work with London-based businesses remotely?

Yes, and we’ve been doing so successfully for many years. Our process is designed for seamless collaboration with remote and hybrid teams, using on-site visits where they add value, video calls, structured reviews, and clear documentation to keep projects moving efficiently.

Do you need to visit our site in person?

Not always, and many projects are delivered entirely remotely. However, we are happy to visit your site and meet in person where this adds value, and clients are always welcome to visit our office in the north.

Why do London-based clients choose us over other agencies?

Clients typically choose us for our combination of senior expertise, industry knowledge focus, and track record of commercial results. We’re outcomes driven, and our process is designed to deliver commercially viable products efficiently, without the overheads of a large city-based agency.

How do you reduce the risk of expensive mistakes or redesigns later in the process?

We focus heavily on commercial and manufacturing alignment before we begin our design process. Identifying all relevant costs, constraints, and opportunities at the start reduces the risk of late-stage changes and redesigns.

How do you handle intellectual property protection?

For both SMEs and larger organisations, protecting intellectual property is critical. We build IP considerations into our process from day one, ensuring secure handling of information and clear documentation of design development at every stage. We can also support design registration processes and collaborate directly with your patent attorneys to help reinforce and strengthen your overall IP position.

What's your approach to managing project costs?

We understand that budgets need to deliver returns. Rather than just quoting a price, we help you understand where your budget will have the most impact. For example, investing more in early research might save significant costs in manufacturing. We provide clear cost breakdowns and help you make informed decisions about where to invest for the best commercial outcomes.

Can you work alongside our existing development team?

If your business has internal capabilities but needs specialist support at critical stages, we can help. We're experienced in integrating with in-house teams, whether that's providing specific technical expertise or adding capacity during peak periods. We adapt our involvement to complement your existing resources.
