But first what is a UX UI Development Agency?

A UX/UI development agency is a team of experts who work collaboratively to create exceptional digital experiences that satisfy user needs and enhance the overall performance of websites, applications, and other digital products. Their primary focus is on the user interface (UI) and user experience (UX) design, which includes every aspect of the digital experience, from the look and feel of the interface to the overall usability of the product. At its core, a UX/UI development agency helps businesses and organizations create digital products that meet the needs of their target audience while providing an intuitive and enjoyable experience. They combine creativity, technical expertise, and a deep understanding of human behavior to design and build digital products that are both functional and aesthetically pleasing. Ultimately, a UX/UI development agency aims to create digital products that not only meet the needs of users but also drive business success.

How we do it


How we do it


At 89Ninety, our UX/UI agency based in Belfast and London, we believe in creating experiences that delight users. We understand that building a website is more than just developing software – it’s about designing an interface that is intuitive and easy to use. Our team of expert developers and designers work closely with you to understand your business goals and target audience, ensuring that every detail of your website is customised to your brand and user needs.

We approach each project with careful planning and collaboration to ensure that your website not only looks great but functions seamlessly. From the initial design to the final launch, we continually monitor and optimise your website to ensure it remains relevant and user-friendly.

At 89Ninety, we are dedicated to staying ahead of the curve in the constantly evolving world of UX/UI design. We believe that every project is an opportunity to push boundaries and exceed expectations. Our team is committed to delivering high-quality, user-friendly websites that drive growth and success for our clients.

Our Approach to UX/UI Planning


Research and Discovery: In this phase, 89Ninety’s team of experienced UX/UI designers conduct extensive research to gain a deep understanding of your business needs and the goals of your mobile app development project. We start by analysing your target audience, industry trends, and competitor offerings to create a comprehensive plan to set you apart. Our team employs various research techniques and methods, including user interviews, surveys, user journey mapping, and other user-centred design processes, to gather valuable insights that inform the project strategy.

Our Approach to UX/UI design


Design and Prototyping: Using the insights gained in the research phase, we create a design strategy for your mobile app that incorporates your brand identity and meets your specific requirements. We leverage the latest design trends, usability principles, and best practices to ensure that the app is user-friendly, intuitive, and visually appealing. Our design team creates wireframes and prototypes that provide a glimpse of the final product, allowing you to provide feedback and make changes early in the development process.

Our Approach to UX/UI development


Development and Testing: After finalising the design and prototype, we begin the mobile app development phase. Our team of developers builds the app using the latest technology, ensuring it is responsive, scalable, and optimised for performance. We take care of all aspects of the development process, including front-end and back-end development, API integrations, and third-party services. Throughout the development process, we conduct rigorous testing to identify and resolve any bugs or issues.

Our Approach to UX/UI Opimisation


Launch and Optimisation: Once the app is ready, we deploy it to the app stores and ensure that it meets all the guidelines and standards for a successful launch. We also offer post-launch support, monitoring and analysing app usage data to identify areas for improvement and optimisation. We aim to help you achieve your desired outcomes and continuously improve your development project to deliver the best user experience possible.

At 89Ninety, we pride ourselves on delivering mobile app development services that exceed expectations. From research to launch and beyond, we work closely with our clients to deliver outstanding results that meet their unique business needs.

Frequently Asked Questions

At 89Ninety, we strive for transparency and honesty in all our interactions. We believe that working with a Creative Digital Marketing agency should be simple and straightforward, leaving you feeling confident in our process.

To help you better understand our services, pricing, and expectations, we’ve compiled this list of frequently asked questions. If you have any additional inquiries, please don’t hesitate to reach out to us. We’re here to make your experience with us as smooth and informative as possible.

As an agency, 89Ninety has been delivering our expert Creative Digital Marketing services since 2014 from our base in Belfast. Expanding our reach across Northern Ireland, the UK, and the United States. 

At 89Ninety, we’re a full-service digital marketing agency. Our services include Experience, Digital Marketing, Public Relations, Creative, and Strategy.

We offer customisable packages to suit the unique needs of your business. Our services can be used independently or combined for a comprehensive, integrated approach.

89Ninety, through the experience of working with a varied clientele, offers three distinct project models. 

These are Project-Based, Retainer, and A La Carte.

Project Based: At 89Ninety, our approach to individual projects is rooted in clearly defined scope and requirements. We use an iterative process that focuses on achieving specific goals, and we work closely with you to make informed decisions and distill your objectives. We support you every step of the way, using proven processes and transparent pricing to help you achieve your goals.

Our project-based arrangements are designed to deliver mutual gains, and many of our clients choose to continue working with us on a retainer basis after their initial projects are complete.


At 89Ninety, we offer monthly, bi-yearly, or yearly retainers for all of our services. This allows us to become an extension of your team and work closely with you over the long term. Our structured, timely execution and regular updates will keep you informed and involved, and our services can be tailored to fit your unique needs and goals.

Experience has taught us that retainers are most effective when they’re used to provide ongoing support after completing individual projects.

A La Carte:

At 89Ninety, we understand that flexibility is key to building strong, lasting relationships with our clients. That’s why we’re happy to provide specific services and deliver individual components that support your brand and products, even if they’re not part of a larger scope of work.

Our one-off services are contract-free and hassle-free, and there are no strings attached.

Contact our offices in Belfast and London to learn more about how we can help your business succeed with our tailored, flexible services.

At 89Ninety, we believe in transparency and honesty in all our pricing. The monthly retainer covers all our services, with the exception of biddable media spend on platforms such as Google Ads, Microsoft Ads, and Facebook Ads. This spend will be billed separately to our management fee, so you’ll always know exactly what you’re paying for. We want to make sure you have all the information you need to make informed decisions about your digital marketing strategy.

“When comparing prices from different digital marketing agencies, it’s important to consider the level of service and expertise included. A lower price may not necessarily equate to a lower level of service. Make sure to carefully review the deliverables included in the quotes you receive, and don’t be afraid to ask questions.

At 89Ninety, we pride ourselves on our transparency and honesty. We’ll always be upfront about the services and results you can expect from us. In our experience, it takes a significant amount of time and effort to achieve the best results, so be wary of agencies that quote significantly lower prices without explaining the potential trade-offs in service or performance. We want to ensure that our clients receive the highest level of service and the best possible results.”

At 89Ninety, you’ll have a dedicated team member who will act as your main point of contact and manage your account on a day-to-day basis. In addition, you may also work with one of our client strategy experts who will help develop your overall digital marketing strategy.

Depending on the project, various specialists from our team may also be involved, working on specific areas such as PPC, social media, or content marketing. We’re always transparent about who is working on your account and the roles they play, and all of our experts are 89Ninety employees. This allows us to provide a seamless and cohesive service that is tailored to your unique needs and goals.

At 89Ninety, we are a digital marketing agency with our main office in Belfast and a satellite office in London. We serve clients across the UK and location is not a barrier to working with us. While we value the opportunity to meet with our local clients in person, we also arrange regular calls and meetings with clients located further away. We believe that open and frequent communication is key to the success of any project, and we’re always happy to travel to meet with our clients for in-person meetings on a quarterly or bi-annual basis. We’re committed to providing the same high level of service and support to all of our clients, regardless of their location.

At 89Ninety, we take the time to thoroughly understand your business and its needs. We believe that this is essential in developing an effective digital marketing strategy.

To gain insight into your business and industry, we conduct interviews with you and your team, conduct research on your industry, analyse internal and external data, listen to your audience on social media, and study your competitors’ online presence. If you’re a local client, we’re also able to spend time working from your office each month to better understand your business operations.

All of this information helps us gain a comprehensive understanding of your business and its unique challenges and opportunities. We believe that this level of knowledge is crucial in developing a successful digital marketing plan that delivers results.

When you start working with us, our Belfast or London team will schedule a kick-off meeting with you and your team. This meeting allows us to gather all the information we need to create a comprehensive, 6-month digital marketing strategy. The strategy will outline the specific actions we plan to take and the dates you can expect to see results.

We believe in keeping our clients informed and involved, so we review and refresh the strategy every 6 months (or more frequently if needed) to ensure that you’re always aware of what’s happening and when you can expect to see progress. Our goal is to provide a clear, transparent plan that helps you track our progress and understand the value of our work.

At 89Ninety, our content marketing team is comprised of highly skilled writers who are dedicated to creating engaging and effective content. Before writing, we conduct thorough research using tools such as Answer the Public, Ahrefs, Google Trends, SEMRush, and Buzzsumo. We also incorporate input from you to ensure that our content aligns with your business goals and targets the right audiences.

We believe that marketing content often performs better when it’s written in a clear, jargon-free style that is accessible to a wider audience. We’re happy to provide examples of the content we’ve produced for our clients, both at our offices in Belfast and London. Contact us to learn more about how our content marketing services can help your business succeed online.

The time it takes to see results from our digital marketing efforts will vary depending on factors such as the channels we use, your competition, your budget, and the state of your website before we begin working with you.

However, as a general rule, you can expect to see an improvement in your online visibility and key metrics within the first three months of our work together. This is because the first three months are typically focused on developing a solid digital strategy and laying the groundwork for a successful long-term project.

Projects that incorporate PPC and biddable media tend to see results more quickly, as these channels can generate qualified web traffic almost immediately. Contact our offices in Belfast and London to learn more about how we can help you achieve your digital marketing goals.
