About
A boutique studio that builds beautiful, dependable websites and apps.
We design and build websites and apps, powered by AI, that bring in customers, save time and grow revenue. Built through close collaboration, with a human-centred focus.
Who we are
Small studio. Serious capability.
Aussi Logique is a boutique website and app studio based in Grasse, near Monaco, and we also meet clients in Sydney. We’re small on purpose, so you work directly with the people building your website or app. For larger phases we draw on an established network of trusted specialists, and you keep one accountable point of contact throughout.
Behind that is 25 years of software, and it began a long way from marketing websites. Our founder started in Sydney, in defence with CSC, moved to Vancouver for aerospace with Hughes Aircraft, then came back to Sydney for finance: banking technology at Sandstone, then software architect at JP Morgan Chase on their investment portfolio systems. He went on to spend more than a decade at Allianz, leading delivery teams of up to 2,500 people across more than 50 countries, and now advises payments and fintech ventures on architecture and scale.
The through-line is software where failure is expensive. That is where our phased approach comes from: ship the core thing first, prove it works with real users, then build on it, because in aerospace, defence and investment banking you do not get to launch everything at once and hope. It is also why taking over a prototype that has outgrown itself is work we know well.
The name isn't an accident. "Aussi" is French for "also", but to an Australian ear it sounds like home. "Logique" is logic, and it gives us our tagline: The Logical Choice. The studio's founder has spent decades building software across Australia and Europe, and that duality is baked into how we work: global range, boutique accountability, always in English. If you're reading this from Australia, Aussi Logique is a registered Australian business, we quote in AUD and we can meet you in person in Sydney; see apps and websites for Australian businesses.

Andrew Mitchell
Founder & CTO
Andrew leads every build hands-on. He has spent 25 years in software that has to work: defence at CSC & Boeing in Sydney, aerospace at Hughes Aircraft in Vancouver, then back in Sydney for lending & banking technology at Sandstone and as software architect at JP Morgan Chase on investment portfolio systems, then more than a decade at Allianz leading global delivery teams across multiple scale agile front end and payment systems. He has advised multiple fintech ventures on architecture and how to scale. That background is why we build in phases: ship the core thing first, prove it with real users, then build on it in agile increments. He architects the app, the backend and the API, and stays accountable from first sketch to App Store launch via our build and support team. No account managers, no handoffs.
