Product-led Development
Apps and Bespoke Software
We help founders, startups and small businesses build rock-solid apps and made-to-measure software to solve real problems
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.
Who we help - and how

How we help
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
“It was a pleasure working with someone of such high intellect, yet more importantly someone who was so humble in displaying it. As founders we were comfortable knowing that finally our React Native apps were in highly capable hands.”
“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.”
“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. They were both 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.”
