Why Antiphono

What sets us apart

  1. 01

    In it for the long run

    Our longest client relationship is eight years old and still going. Month twelve should beat month one, so we write everything down as we go.

  2. 02

    We've sat on your side of the table

    Ben ran product and design at the Seven Network and Pacific Magazines. We know what a roadmap, a board and a launch date feel like.

  3. 03

    Early to AI, and open about it

    We've spent the past two years building AI into how we research, design and build, and we'll show you exactly where it's used and who checks it.

  4. 04

    Part of your team, not down the hall

    We join your stand-ups, work in your tools or ours, and leave everything with you.

Testimonials

In their words

“Ben is without a doubt one of the most talented UX and product design leaders I’ve ever had the pleasure to work with. So when we started to think about reimagining the FW UX I knew he would bring the expertise and engagement style the team needed.”
Mel Lee, Head of Product, Future WomenMel LeeHead of Product, Future Women
“When AI changed how we approach design, Ben embraced the challenge with real enthusiasm and showed immediate expertise. He helped us move faster without losing the care and craft our users expect. I couldn’t recommend Ben more highly.”
Ali Linz, Co-Founder, GroupTogetherAli LinzCo-Founder, GroupTogether
“Ben is an incredible design partner who transformed our digital presence at FW. He helped define our digital brand and built our design system from the ground up, creating a cohesive look and feel across all digital touch-points from websites to emails. His work elevated not just how our products looked, but how easily customers could use them and how well they performed, including improving our sales funnels and conversion.”
Lucy Hoult, Head of Product, Future WomenLucy HoultHead of Product, Future Women
“Ben came recommended to us, and he more than lived up to it. We brought him in to help with the UI and UX of the Quartile 5 platform, taking a complex engineering assurance product and making it clear and usable.”
David Winsor, Founder, Quartile 5David WinsorFounder, Quartile 5
“Ben is continuously incredible to work with, a top tier talent and I would recommend him and his team to anyone looking for exceptional UX design and research. I can’t wait for the next project we do together!”
Mel Lee, Head of Product, Future WomenMel LeeHead of Product, Future Women
“Ben is our one and only UX designer for our 5 million user brand, and he’s made that role his own. Although he’s freelance, he’s never felt external. He’s dedicated, fully part of the team, and knows our brand and product as deeply as any of us.”
Ali Linz, Co-Founder, GroupTogetherAli LinzCo-Founder, GroupTogether
“Ben built strong relationships and became a trusted, influential partner to stakeholders at every level of the business. He also worked brilliantly with our engineering team, bringing a deep technical understanding to his design work. He could get to the heart of a complex problem, apply thoughtful design thinking and deliver a practical, effective solution at pace. That combination was invaluable in our fast-moving scale-up environment.”
Lucy Hoult, Head of Product, Future WomenLucy HoultHead of Product, Future Women
“It was a highly collaborative process, and the product is better for it. Ben also thought a few steps ahead to make sure it wasn’t only suitable now, but the future too. I’d recommend Antiphono to anyone building a product that needs to work for real users.”
David Winsor, Founder, Quartile 5David WinsorFounder, Quartile 5
“Ben is a wonderful person as well as a great professional. I wouldn’t hesitate to recommend him and hope we can work together again in the future.”

“I worked with Ben to develop a new brand identity and design system for my strategy consultancy and newsletter. I was impressed by his ability to grasp my underlying vision and translate it into a timeless, distinctive visual direction. He is highly collaborative and thoughtful in the way he works, and skilled at bridging commercial objectives with strong design principles. This made him an invaluable partner throughout the process. I can’t recommend him highly enough.”
Alexi Gunner, Founder, Idle GazeAlexi GunnerFounder, Idle Gaze
“We needed to design an accessible and engaging experience for users with low digital literacy and Ben’s approach was thoughtful and deeply rooted in experience - and translated into a significant engagement uplift and our FW jobs academy members experiencing our programme the way it was intended.”
Mel Lee, Head of Product, Future WomenMel LeeHead of Product, Future Women
“There’s no ego with Ben. He takes ideas and feedback openly and turns them into better work, which makes him a delight to collaborate with. He has owned our UX research process from start to finish, from running the research to analysing the findings and turning them into clear design decisions.”
Ali Linz, Co-Founder, GroupTogetherAli LinzCo-Founder, GroupTogether
“He was always looking ahead, exploring how AI and emerging tools could improve the way we worked. I really valued his curiosity, adaptability and the care he brought to our partnership.”
Lucy Hoult, Head of Product, Future WomenLucy HoultHead of Product, Future Women
“What stood out most was how well he listened to understand each unique use case, user and problem we were trying to solve. He always had good insights and suggestions, however never came in locked into a particular path which allowed the product to grow. He would lay out a range of options, talk through the trade-offs with us, and collaboratively worked through the problem until we found what best fit.”
David Winsor, Founder, Quartile 5David WinsorFounder, Quartile 5
“Ben is a digital rockstar gun. Hire him!”

He takes the initiative and brings ideas to life in a way that helps everyone get on the same page and make decisions faster. He also works closely with our technical teams to make sure his designs will work with our technology, which gives us confidence in what we’re agreeing to.”

Beliefs

What we believe

Your judgement built something good enough to raise money. After the raise, the cost of a wrong call goes up, and evidence needs to sit alongside instinct.

AI tools can produce a convincing interface in minutes. They can't tell you which one your users need, or whether it worked. That's where we spend our time.

Most teams we meet have analytics installed and dashboards nobody acts on. We start with the decision you need to make, then find the evidence for it.

When a variant takes hours rather than weeks to make, picking one idea and hoping is no longer the cautious option. We test, and let your users decide.

We design and build with your components, to your conventions, so what ships is what was designed.

Decisions and research belong where the next person can find them, which is why the project record stays with you.
