A web agency in the Territoire de Belfort.
Appup is an independent studio based in Morvillars, between Belfort, Montbéliard and the Swiss border, with a single goal: to create tools that truly help businesses grow.
Our story: custom tools that serve businesses
We founded Appup on a simple conviction: every business deserves digital tools worthy of its ambitions. Not patched-together solutions, not generic templates, real products, custom-built, made to last.
We've worked with craftspeople, SMEs, startups and independent professionals, in the Territoire de Belfort, the Pays de Montbéliard, the Swiss Jura and far beyond. Every time, the finding is the same: when the tool is well made, the business grows.
13 years of experience later, we remain a tight-knit, curious and demanding team. AI, new stacks, best practices: we train continuously to offer you the very best.
Our values
Not words on a poster. Principles we apply to every project.
Quality above all
We never ship something we're not proud of. Every project gets the same care, from a showcase site to a complex platform.
Transparency
No jargon, no surprises. We communicate clearly about timelines, costs and technical decisions. You always know where we stand.
Long-term partnership
Our relationship doesn't end at delivery. We support our clients over time, evolve their tools and stay available.
Our approach
What sets us apart is how we work, not just what we deliver.
We understand before we code
Every project starts with a thorough scoping phase. We seek to understand your business, your users and your real goals, not just your specifications.
Advice, not just execution
Our role isn't limited to building what we're asked. We bring our expertise to question, propose and optimise every decision.
We build to last
Clean architecture, maintainable code, careful documentation. What we deliver must be able to evolve in two years without a full rebuild.
We work together
No black box. You're involved at every key step. We ship often, validate together and adjust in real time.
A team of enthusiasts
Developers, designers, consultants, each an expert in their field, all aligned on the same goal: your success.
At Appup, we believe the best products come from collaboration between people who trust each other and speak frankly. No rigid hierarchy, no bureaucratic process: experts working together, with passion and rigour.
We also share our know-how
Beyond development, we offer web training for all levels, for companies, teams and individuals.
All levels
From complete beginner to seasoned developer, our programmes adapt to your starting level.
Practitioner trainers
Our trainers work on real projects every day. They teach what they practise.
On-site or remote
Sessions on-site or by video call, depending on your preferences.
Tailored content
Every programme is tailored to your specific goals, no generic content.
