Software development in Vienna: web apps and platforms built for long-term operation
Custom software for companies, associations and media. Ahoi Kapptn! develops web apps and platforms with a dedicated team, from the first decision through to ongoing operations.
We combine software development and web development in Vienna with responsibility for the finished product. For the Vienna-based ÖFB (Austrian Football Association), we developed ÖFB TV into the central streaming platform of Austrian football: new UX/UI, a scalable stack and a smooth migration from the previous provider.

Software development in Vienna for your organization
We develop custom software that maps your processes and connects your existing systems. Whether it's a customer portal, an internal application or a media platform, what matters is which task your users can reliably get done with it.
For companies and associations in Vienna, this often means bringing business units, IT and external partners together in one product. Together we clarify what data is needed, who makes the decisions and which features should go live first. The result is a scope you can actually implement.
Custom software in Vienna, agreed in person
Our Vienna office is at Diefenbachgasse 54A/16, 1150 Wien, in Rudolfsheim-Fünfhaus (15th district), and has been open since 2026. You can discuss requirements on-site and work with our team in Vienna, in Linz and remotely. Find out more about our location at Ahoi Kapptn! in Vienna.
Ahoi Kapptn! brings 13+ years of experience, 20+ people on the team and 40+ completed projects. Product design, web development and backend work in the same dedicated team, from the first sketch through to operations.
Web development in Vienna: web apps, backends and integrations
We develop web apps for organizations that want to bring content, business logic and existing systems together in one usable application.
Web apps in Vienna
We use Next.js to build applications that run in the browser. We use Payload CMS when your team should manage content itself and needs a suitable editorial system.
Backends and APIs
We develop the business logic behind your application and the APIs for data exchange. Scaling, documented interfaces and monitoring are part of the planning, so growing usage is accounted for in operation.
Integrating existing systems
A middleware layer bundles interfaces and translates data between systems. This lets your web app, existing databases and external services work together, instead of the same information being entered several times.
Four projects that show what we deliver
ÖFB TV, StadiumADS, Just Jobs and SAP show our work on streaming, platform processes and interactive web interfaces. The tasks differ, but in each case our responsibility ranged from concept to technical implementation.
ÖFB TV: streaming and media platform
The ÖFB needed a central platform for live matches, highlights and replays. We renewed the UX/UI, implemented a scalable stack and supported the move from the previous provider. Single sign-on connects the offerings for fans. The platform reaches more than one million streaming minutes per month and has been in continuous use since its launch in August 2025.
StadiumADS: presenting advertising space in the browser
StadiumADS makes stadium and jersey advertising space presentable in interactive 3D. We were responsible for the architecture, frontend and API structure. We integrated the 3D models supplied by the client into the web experience and optimized them. Clubs can present sponsorship space interactively and send it directly to potential partners.
Just Jobs: from staffing needs to working hours
For Just Jobs, we built the app and web platform for flexible work in Austria. Companies request staff for hospitality, promotions and events digitally, manage assignments and confirm working hours. The workflow connects companies and workers in one shared process.
SAP: explaining complex content interactively
The SAP Interactive Experience combines classic web elements with video, animation and interaction. We developed a React-based website that conveys content about the world of Industry 4.0 visually. The modular architecture allows additional topics and animations to be added without a complete redesign.
Platforms in continuous operation
Streaming, a marketing platform and a job platform.
How scope, timeline and budget become predictable
You start with a free, no-obligation intro call and, after a compact discovery phase, receive a solid plan. We discuss your goal, users, existing systems and open questions before we define the implementation.
The discovery is fixed-price. It clarifies scope, timeline and budget before any code is written. This lets you decide internally what to commission and which dependencies need to be resolved first.
We bill development as a monthly team retainer. Each month's costs are fixed in advance, while the scope stays flexible. The same experienced team supports your product through development and optimization.
If your project also needs mobile use or AI, we include those requirements in the planning. Find out more under app development in Vienna and AI for organizations in Vienna.
Operations, maintenance and security are part of the product
We support your software after launch and plan operations, maintenance and security requirements from the start. Monitoring, updates and further development need clear responsibilities, so your organization has a point of contact when problems come up.
We clarify which services, response times and responsibilities you need for your application. At Ahoi Kapptn!, Simon Kapl, COO and co-founder, is responsible for delivery and operations. Find out more about our services under security and maintenance.
For data protection and access control, we take into account roles and permissions, audit logs and options for EU hosting or on-premise. We clarify data flows and GDPR requirements within the project. Our ISO 27001 certification is in preparation. You can find the principles of our information security management at Information security at Ahoi Kapptn!.
Frequently asked questions about your software project
The price depends on scope, interfaces and operating requirements. After the free intro call, a compact, fixed-price discovery establishes the plan for timeline and budget. Implementation runs as a monthly team retainer with monthly costs known in advance.
A reliable timeline emerges during discovery, once features and dependencies are clear. Existing systems, data migration and approvals affect the schedule. Together we decide which scope should go live first.
We clarify data flows, access rights and GDPR requirements within the project and consider EU hosting or on-premise as options. Roles, permissions and audit logs support controlled handling of data. At Ahoi Kapptn!, ISO 27001 certification is in preparation.
Ahoi Kapptn! continues to support products after launch. The dedicated project team stays involved from the first sketch through to operations. We agree on the scope of maintenance, monitoring and further development, as well as responsibilities, to suit your needs.
