Hi, I'm Jack, a London-based product design & development freelancer and solo founder. Building human-first intelligence products for the synthetic age.
Designing and building products that feel human first. Not just built. Not just tools. But turning complex ideas into culturally aware, contextually adaptive, and emotionally engaging products that feel alive for the machine-human world.
Mass
My mum thinks it's cool. My friends think it's meh. Getting human opinion is hard. It's time-consuming, expensive, and I'm not sure I can trust the result. That's why I built Mass, a platform to deploy hundreds of synthetic human personas that think, reason, and respond like my target audience. They're brutally honest and unfiltered, giving me a real sense of what my target audience wants in minutes, not months. And at a fraction of the cost. Understand perspectives, validate messaging, explore positioning, and more before committing to the real human research.

Over the last 20 years, I've been fortunate to work with global brands including Google, IBM, Air New Zealand, Kpler, EE, News UK, Tesco, and The Economist, as well as leading digital agencies and startups across the UK, Middle East, and Oceania. Now I'm building my own products and helping others build theirs.
If you're looking for a product design & development freelancer, I'm your human. Either hands-on or as a consultant, I can help you build your product.
If you'd like to collaborate, discuss strategy, or explore how I can help, please get in touch with me at jack@thingsthat.com.
