Why 72 Days?

In under 3 months, you can turn an idea into a real product and start gathering valuable insights from actual users. We focus on delivering something functional and meaningful, so you can learn, iterate, and grow with confidence.

A clear path from idea to app store

We know that building an app isn't just about writing code—it's about turning your vision into something real. From day one, we help you map out the journey, from discovery and planning to development, launch, and beyond. Rely on our experience to get there on time, with the right foundations in place.

Number 72

Human-centric development

Technology should serve people, not the other way around. We're not here to blindly churn out code—we're here to deeply understand your business and your users, their needs, and how your app can make their lives better. That means thoughtful decision-making, real conversations, and solutions that actually solve problems.

Why us

Aligning strategy and technology

Your business strategy should drive your technology choices, not the other way around. We help you make smart, sustainable decisions—whether that's choosing the right architecture, prioritising features, or knowing when to say no to something costly that won't move the needle.

Built fast, designed to last

Speed matters, but so does sustainability. We move quickly to get a working product in users' hands, but we're careful about which corners we cut. Our goal is to build with strong foundations and create software that's lean, adaptable, and ready to grow with you.

Scales with money on one side, app stores on the other

Your product and tech partner

We don't just build and bail. We're invested in making sure you're equipped to own and evolve your app long after launch. Whether that means knowledge sharing or ongoing support, we're here to help you succeed for the long run.

Made my app come to life! Russ and Chris guided me through the entire process and took the time to understand the vision to deliver on value. Their knowledge and experience is phenomenal. Thank you

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.
