Designed. Engineered.
Delivered.

Engineering-led product development from early research through to manufacture.

We take responsibility for delivery with experienced, hands-on leadership throughout.

Our founders led the Dyson Airwrap, Dyson Cordless Vacuum Platform, and Elvie Breast Pumps — and have delivered products across consumer electronics, medical devices, connected products, and wearables.

“We work with founders, product leads, and engineering teams who need senior capability without agency overhead. If you want to work directly with experienced engineers who stay hands-on throughout — we’re a great match.”

Our Core Values

We translate user insight into clear, purposeful design that resonates with real users.

Designed for people

Robust engineering underpins every project, ensuring performance, quality, and long-term reliability.

Engineered to perform

We design with production in mind from day one, reducing surprises as you move toward manufacture.

Optimised for Manufacture

We embed inclusive and sustainable thinking to support long-term value, not short-term fixes.

Responsible by Design

What we’re known for

We bring a broad skillset and are known for our ability to take ownership and move projects forward with confidence.

End-to-end delivery

We’ve taken products through global launch and mass manufacture before — and we take the same ownership on every project we work on.

Senior, hands-on involvement

You work directly with Dan and Chris throughout. We don’t hand projects down to junior teams.

Comfortable with complexity

Electro-mechanical products, embedded electronics, regulated medical devices, and connected products are our day-to-day.

Friendly approach

We work the way that suits you — embedded in your team, leading independently, or somewhere in between.
