I'm a product and design lead who cares about doing work which leaves the planet better than I found it.


2017 – present

Senior Product Manager, Unmade

Unmade aims to shift the fashion industry by allowing brands and their consumers to create and purchase exactly what is wanted before it’s made, reducing waste and creating an efficient, digital-first fashion supply chain from design to manufacture.

I am responsible for making sure we make the right product decisions to meet the needs of our B2B customers, which include many of the world’s biggest fashion brands and groups, and to ensure that Unmade creates a forward-looking, robust and market-driven Saas product to allow the company to scale sustainably and keep innovating.

I've helped to build and maintain an enthusiastic, transparent and focussed product practice and culture; led transformative product initiatives to sustainably scale our product and service offering; and worked closely with business development to take the product to market and bring industry & customer insights into the product strategy.

2014 – 2017

Head of Product Design, Mastered

My leadership-level role at this startup, who offer an education and networking platform for emerging fashion talent, involved bringing together content, marketing and product to create a user-centric experience that delivered measurable ROI to our customers while enabling rapid growth through refining and scaling the services offered.

Driven by customer insights and needs, I conceived, implemented and measured product and service improvements to increase customer retention, engagement and NPS, such as delivering personalised mentoring and written feedback to students at scale, as well as iterating on the sales funnel and marketing materials to increase conversion.

I managed a small design team, collaborated with a cross-functional leadership team to set and deliver against company OKRs, and reported metrics & results to senior leadership.

2012 – 2013

Lead Designer, Sidekick Studios

At product studio Sidekick, we helped large organisations get ideas off the ground. I worked within small multidisciplinary teams to concept, design, test and ship new products to fix internal or customer problems for clients including Cancer Research UK, Comic Relief and Red Bull, and gave those orgs the skills and tools to continue iterating and learning.

2011 – 2013

Product Design Consultant / Contractor

While freelance, I offered a variety of product and design services for clients including Adaptive Lab, V&A Museum, Code Club and Provenance. Projects included a data visualisation dashboard, story-driven product demos, and an internal intranet system.

2009 – 2011

Designer, Poke London

As a UX/UI designer, I delivered innovative digital experiences and products for clients including Orange, Skype and Manchester City Football Club.



I #weeknote and sporadically jot down other notes on product practice and startup culture on Medium. I have an even more sporadically updated travel-ish blog here.


The last few books I have enjoyed: How To Own The Room; Spineless; How to Change Your Mind. Find me on Goodreads here.
