Your experienced product design and development team
After initially focusing on designing and building MVPs for early-stage startups, over the past 10 years we’ve grown to work with larger companies like Tysers, Humn and PwC’s innovation team. We deliver new products and features, or, work as an embedded team improving existing software, making sure it delivers what users actually need.
We’re all about making the digital world easy to navigate, building interfaces that are intuitive to use, maintain and allow people to get the job done. We’re a small, highly effective team all based in and around (occasionally) sunny London who love things design and tech related.

Our values are the core of everything we do
We’re problem solvers
We make products that solve real business problems. They look great doing it too, but function comes first.
We put people first
People are at the core of everything, whether they’re a user of your product or a member of our team.
We take pride in our work
We pay attention to the details, and make sure things are done right, not just done.
We’re open and honest
We’re honest about our opinions, and transparent in how we work. We value fairness, clarity and integrity.
We protect the planet
The planet is burning and we have a duty to protect it. We work to reduce the environmental impact of our business. You can too using the Inktrap Sustainability Toolkit.
Our experience
Having worked on well over 100 products in the past 10 years, we have a broad range of experience across industries and technologies. We’ve designed risk insight platforms for startups, built membership platforms, created learning tools for multinational corporations and everything in-between.
We take pride in our ability to really understand the goals of our stakeholders and the users of their products which leads to a better solution in less time, using our tried and tested process we can apply to any brief.

Creating an industry news app for tax professionals
The indirect tax team at PwC wanted to provide a better way to keep clients up-to-date with the latest sector news and changes. Due to the ever changing nature of local tax rates, by creating a mobile focused news app their clients could be alerted to updates in real time. We worked with their business team to turn this vision into a straightforward feature set, then with their development team to support the design’s implementation.

to design the first version, followed by 14 incremental updates

providing an intuitive user experience with native Android and iOS apps


By configuring jurisdictions and sectors of interest, users can set up a curated stream of relevant news, only receiving updates which are important to them.

We also designed a dashboard tool for tracking tax changes over time using embedded BI analytics, including advanced user access configuration.
Making personal investing interesting and accessible for Tillit
We designed a new web app for Tillit (formerly VINCO), which allows individuals to invest in funds handpicked by trusted experts. Our work included hosting UX workshops, conducting user interviews and tests plus creating UI prototypes.

Fuelling victory with data-driven design to improve racing performance
Teaming up with Toyota Connected, the innovation arm of Toyota, we redefined the data experience for their Gazoo Rally team. We designed intuitive tablet and mobile prototypes that enabled real-time tracking of critical race data including vehicle data and driver performance for team owners and drivers.
Collaborating closely with their internal product manager, we transformed complex requirements into an intuitive, user-friendly interface, providing the team with a powerful toolset to ensure peak performance.
2 weeks
including wireframing, user-testing, UI design and prototyping
2 prototypes
across mobile and tablet prototypes for team owners and drivers

In order to ensure the effectiveness of the final designs, the wireframes were tested with the Toyota race team in Finland, validating requirements and optimising performance

Our team developed comprehensive prototypes for both mobile and tablet interfaces, catering to the data tracking needs of both team owners and drivers
Helping therapists reduce the time they spend on clinic updates
Harley Therapy connects therapists and clients via an online platform. They approached us to design a new mobile web app to help therapists manage their practice and complete clinic updates at the end of each session.
We worked closely with the therapists to understand their needs and typical workflow. Our solution included contextual questions to enable users to manage booking and scheduling for clients, as well as less common cases like no-shows, holidays and late cancellations.
After our initial sprint we continued working with the Harley Therapy team on their client experience, increasing conversion rates in their booking flow by over 300%.
10 days
to create and test an initial prototype of the mobile web app
3 sprints
to improve the therapist and client experiences


The web app includes a dashboard of upcoming appointments, notifications, and payout information

We mapped out the different scenarios that a therapist could face when completing a clinic update
Designing a learning app to train financial professionals
Having created an MVP validating the customer interest and technical viability for a spaced learning app, the Learning Lab team needed a fresh design to be rolled out across web, iOS and Android apps. We worked with them on a product mission to revamp the UX and UI, create a coherent design system across the whole product ecosystem, suitable for white-labelling with a broad range of their partners.
6 months
supporting their business and development teams
4 products
across Android, iOS and web, plus a course builder & admin tool


Spaced learning requires daily quizzes to be completed to reinforce previous lessons. This required a mobile-first approach and native iOS & Android apps

Learning Lab can only be effective if it contains quality content. We designed a Learning Management System to make it easy to create, assign and update courses & users
