Which of these sounds like you?
We build for businesses that want to move fast.
Tell us where you fit and we'll show you how we can help.
A business nobody can find online
Your site looks fine but isn’t bringing in what you need. You want one built to rank on Google and be cited by AI assistants from the start.
A founder whose MVP won’t scale
You built it with a no-code tool like Lovable or Bubble, or with a freelancer. It works, and now it is buckling under real users.
A company selling in more than one language
You are expanding past a single market and need a site or app that handles the second language properly.
An early-stage startup
You need to ship a first app fast, without cutting quality, to show users or investors.
A field-service or trades business
You're losing hours to paperwork and phone-chasing and want a simple but powerful app that pays for itself.
A premium or client-facing brand
You want a website and an app that feel as considered as the brand behind them, handled discreetly and GDPR-ready from the start.

What clients & partners say
We were drowning in paperwork and WhatsApp groups with no realtime overview: time and expenses on paper, then re-typed back at the office. Aussi Logique built us an app that fits exactly how we work on site, and it's cut our project managers' admin time by around half. Andrew understood our trade, not just the technology, and more importantly; he is always able to put himself in our shoes and is really easy to communicate with!
Our old site didn't come close to reflecting the standard of our work. Aussi Logique redesigned it into something genuinely premium (clean, fast and beautiful on a phone) and it's bringing in better enquiries. They understood that for us, presentation is everything.
Before, we were almost invisible on Google. Aussi Logique rebuilt our website to be fast, clean and properly optimised from the ground up, and we now show up for the searches that actually bring us work.
Love your work Aussi Logique! Now we finally have a professional webpage - such an improvement over the previous one.
I've worked alongside Andrew for many years and have consistently been impressed by his judgment, technical leadership, and ability to make clear, confident decisions. He communicates requirements effectively, provides strong direction, and keeps projects moving forward without unnecessary delays. From a supplier's perspective, that clarity makes a huge difference. Andrew is someone I would trust to lead a complex build and deliver the right outcome.
Good to know
Common questions
How much does a website or an app cost?
It depends on scope, but websites start around €2,500, a focused "app in a week" MVP around €4,500 and a full product around €15k. Because we build with AI assistance, we deliver faster and for less than a traditional London or Paris agency. We always give a clear, fixed-price estimate before any work starts.
Do you build apps as well as websites?
Yes. Alongside websites with SEO built in from the ground up, we build mobile and web apps and the cloud backends behind them. Same AI-accelerated approach, same craft, and the same engineers.
How long does it take?
A focused MVP typically takes 4–8 weeks as a fixed-scope sprint. Larger products are phased. We share a realistic timeline up front and keep you updated throughout. No surprises.
Where are you based, and do you work remotely?
We’re based in Grasse, near Monaco, and we also meet clients in person in Sydney. We travel to London often and work with clients there remotely, such as The Landscape Gardener, a London landscaper. Clients elsewhere in Europe, including the Netherlands, work with us by video.
Is what you build GDPR-compliant and secure?
Yes. We build with a security-first, GDPR-aware architecture from day one; compliance is designed in, not bolted on. This matters especially for wealth, healthcare and professional-services clients handling sensitive data.
Can you handle design as well as development?
Yes. UX and UI design are core strengths. We make sure what we build is genuinely intuitive, because an app people find confusing is an app they won’t use.
