Team of Two

Chris
Product & AI
With more than 15 years of experience building websites, apps, and digital products, Chris has worked with startups building their first product to established organisations tackling complex technical challenges. He's particularly interested in how AI can be used in practical, meaningful and safe ways to create better products, streamline processes, and help businesses work smarter. Away from the keyboard, you'll usually find him running, cycling, strength training, or being kept on his toes by his two young kids.

Russ
Product & Engineering
Russ has spent more than 25 years helping organisations deliver successful digital projects. Early in his career, he worked with well-known brands including BT, Unilever, and Pret A Manger, leading the delivery of large-scale software initiatives. Today, he enjoys bringing that experience to smaller organisations, helping them make smart technology decisions and deliver projects with confidence. Outside work, Russ has a passion for music and game development, and is currently focused on ensuring his five-year-old daughter becomes a formidable Mario Kart competitor.

Why 72 Days
Small by design. Senior by default.
A lean senior team
You work directly with us when making product and technical decisions - not a layer of account managers and junior developers.
Product-minded delivery
We start with the problem, the users and the business context, then help you decide what to build and what not to build.
React Native expertise
Mobile specialists since the early React Native era, shipping and maintaining real apps to the App Store and Google Play.
Bespoke software & internal tools
Dashboards, portals, workflow tools and internal apps that fit the way a business actually works.
Fast, but sustainable
We move quickly and cut the right corners, without leaving expensive foundations to fix later.
Human communication
Plain English, direct access, and clear explanations of technical decisions for technical and non-technical stakeholders alike.
AI-assisted, human-led
AI allows us to deliver software at a pace that simply wasn't possible a few years ago. At 72 Days it's guided by experienced engineers who know what to build and how to build it well.
Business-first thinking
The best technology choice is the one that serves the business, the users and the current stage of the product.
Who we’ve worked with
Brands we’ve worked with across our careers
“72 Days has been a critical partner to our business over the past few years, and we feel incredibly fortunate to have found them.
As a startup, their flexible model has allowed us to scale our team up and down as needed, helping us deliver against our objectives without significantly increasing our fixed costs. They are genuine mobile and product experts. Their experience has enabled us to develop and launch features more quickly, with fewer issues during QA and, ultimately, happier customers. They are also a pleasure to work with, and our team genuinely values the collaborative relationship we have built with them. We would highly recommend 72 Days to any business looking for an expert, dependable and flexible product development partner.”
“Working with the team has been a fantastic experience from start to finish. As a non-technical team, we needed a partner who could take the time to understand our business and translate our ideas and challenges into a platform that genuinely worked for us.
The consultation process was incredibly valuable. They didn’t just take our requirements at face value — they asked the right questions, really dug into how we operated, and helped us identify and articulate problems that we hadn't fully defined ourselves. From there, they worked collaboratively with us to develop features and solutions that addressed those challenges in a practical, user-friendly way. Throughout the project, Russ and Chris were supportive and patient, making what could have been a daunting technical process feel straightforward and collaborative. We always felt listened to, understood and involved in the decisions being made. The end result is a platform that much better reflects how we work and has made a meaningful difference to our day-to-day operations. 72 Days combined technical expertise with a real understanding of our business, which was invaluable, and I wouldn't hesitate to recommend working with them.”
“As founders we were comfortable knowing that finally our React Native apps were in highly capable hands.
It was a pleasure working with someone of such high intellect, yet more importantly someone who was so humble in displaying it.”
“Chris & Russ are hands down the best external developers we have ever engaged with.
Their technical expertise and experience is phenomenal but it is their understanding of and focus on the customer/user that really sets their work and process apart from the majority of the market. I would highly recommend them (and indeed already have) to anyone that was serious about converting their ideas into reality.”
“They were brilliant to work with, and incredibly knowledgeable, helping us to iterate our product, develop our roadmap and be ready for the next period of growth
It was a huge pleasure to work with Chris & Russ. Having come highly recommended, we reached out to them to provide short term support Hibi at a critical time as we prepared our tech infrastructure for a wider market roll out.”
