Websites & platforms
Present your business, sell a service or equip your teams: we design the journeys, CMS and features you need. A brochure website keeps a scope suited to its purpose.
Websites, apps and platforms.
From start to finish.
We design and develop your website, app or platform. From the first user journey to production, we move quickly in short cycles, whether building from scratch or improving an existing product.
Our approach
Move fast. Build to last.
We agree on a useful first release, develop in short cycles and show you the progress. You can test, decide and adjust before launch.
Website development in detail02
Mobile apps
iOS and Android apps designed for everyday use: sign-up, navigation, payments or notifications. We handle development, testing and preparation for app store submission.
03
Back-end, AI & integrations
Connected accounts, data and tools: we develop the APIs and integrations you need. AI becomes part of useful workflows, with defined access and human approval for sensitive actions.

Expansion
Rebuilding a European Aerospace & Defence fund's website
Expansion is an early-stage fund supporting European Aerospace & Defence entrepreneurs, from pre-seed to Series B, with a clear ambition: support European technological sovereignty. The website needed to make this positioning immediately clear to founders, investors, industrial partners and institutions, while showcasing a portfolio spanning satellites, space data, in-orbit services, secure communications, defence AI and autonomous systems. The work involved rebuilding the entire website to give the fund a more authoritative, clear and operational digital presence, presenting its investment thesis, team, portfolio, news and company submission journey.

WhyNotYou
Creating an AI platform to rethink job searching
WhyNotYou is a platform designed to rethink job searching through a simpler, more direct and enjoyable approach than traditional journeys. ligne8 Studio supported the entire product: a mobile app for discovering opportunities, creating a profile, applying more easily and enjoying a smoother experience than on traditional platforms; an employer back office for posting jobs, managing applications, reviewing candidate profiles and managing a presence on the platform; and AI integrated into the product to improve the user experience, from profile creation assistance to surfacing relevant opportunities, analysing applications and improving interactions between candidates and employers. The aim was to create a complete product that is useful for candidates and easy for employers to use. Two months after launch, the app had reached the App Store Top 15, only a few places behind LinkedIn.

Vito
Building a complete platform for chess and backgammon communities
Vito is a complete product for organising and playing chess and backgammon in person. The work spans several surfaces: a mobile app to find nearby opponents, join clubs and venues, create quick games, enter tournaments and track scores, ratings and history; a Firebase back end for authentication, data, notifications, payments, rankings and sensitive workflows; a Next.js back office to manage operations; and a public website with product pages, deep links and universal links. The challenge was to build an ambitious, social and operational product foundation combining geolocation, messaging, groups, tournaments, Stripe payments, community content, notifications and AI-assisted board analysis.

Stanton Wallace
Rebuilding a Talent Management consultancy's website
Stanton Wallace, an independent French consultancy in Talent Management and Strategic Intelligence, needed a website reflecting its demanding positioning: reveal the strength of talent, inform decisions and support leaders in sensitive situations. The work involved completely rebuilding its corporate website to create a premium, clear and credible digital presence around four core areas: Executive Search, Decision Intelligence, Collective Intelligence and Convergence. The challenge was to create an elegant, readable and reassuring institutional experience, with enough editorial depth to convey the firm's distinctive methods, evidence and human approach to strategy.

Our method
Short cycles
all the way to a working product.
Versions to test, regular demos and approval at each milestone. Speed comes from a clear scope and decisions made at the right time.
Define the first release
We review your existing systems, use cases and access. Together, we choose the priority journeys and acceptance criteria.
Build and test together
You get working versions throughout development. We test key journeys and incorporate your feedback within the agreed scope.
Launch and hand over
After acceptance testing, we prepare the launch on your accounts, documentation and onboarding. We agree on support and future improvements together.
FAQ
What types of products do you develop?
We work on brochure websites and their CMS, iOS and Android mobile apps, web platforms, SaaS, back offices and internal tools. Pages, features and integrations are chosen for each project, with or without AI.
Which technology stack do you use?
We choose technologies based on use cases, existing systems and maintenance: React and Next.js for the web, React Native and Expo for mobile, Node.js or Python on the server, and Firebase or Supabase for data and access. CMS, cloud and AI services are selected for each project. You do not need to choose these tools before our first conversation.
Can you take an MVP through to production?
Yes. We start with a first version focused on essential journeys, then develop it further. Testing, access and production deployment are prepared from this first release; subsequent features are prioritised with you.
Can you take over an existing website or app?
Yes. We can review an existing codebase, identify technical debt, stabilise critical journeys, improve the architecture and resume development without necessarily starting from scratch.
How do you deliver quickly without sacrificing quality?
We focus the first release on essential uses and provide regular demos. Key journey testing and your approval are part of every delivery. Timing depends on features, content, access and integrations: a brochure website and a connected app do not follow the same schedule.
What happens after launch?
We deliver the agreed code, access and documentation on your accounts and help your team get started. You can continue with us or hand the project over. Support, fixes and new features have a defined scope; hosting, licences and AI usage remain separate costs. On-call cover or guaranteed availability require a specific agreement.
