A proof of concept is a demonstration of the feasibility of an idea. It allows you to test on a small scale whether an AI app development works as planned before making larger investments in a full-fledged product. This is often necessary to convince investors.
Java is a mature, high-performance technology, and the Vaadin framework enables the rapid development of modern web UIs. We have many years of experience with this tech stack, resulting in a reliable, high-quality solution.
It depends on your use case. Options include existing AI services (such as OpenAI GPT for natural language processing) or machine learning frameworks (e.g., TensorFlow) for custom models. We select the solution that best fits your project.
At the beginning of the project, we work closely with you to clearly define requirements and goals. During implementation, we keep you informed with regular updates and gather feedback to ensure the outcome meets your expectations.
Yes, that's possible. We plan the software architecture from the outset to ensure further development is feasible. After the PoC is completed, the project can be gradually expanded into a productive solution using the insights gained. APX-PS GmbH can take over the implementation and, in this case, will credit the PoC costs toward the final product.
You'll receive the complete source code, documentation, and a working prototype. If you'd like to subsequently implement the app in production, we're ready to support you. We'll take care of the setup, and you only pay the monthly hosting fees for as long as you want to present the web app live.
