The goal of this final paper is to show the process of product development from concept to realization on the example of the Klu software, a SaaS business case. As a business case, the Klu product was chosen, which goes through all the key stages of development, from the initial idea to commercialization. The paper analyzes each step in the product development process, including idea generation, testing, concept and design development, marketing strategies, market testing, and the final product launch. The Klu product is particularly interesting because it fits flexibility and accessibility, and SaaS is a good example of how software can be successfully developed and launched through this model. In the first stage of development, generating ideas, the possibilities and needs of the market are considered, and Klu was developed with the aim of solving specific business challenges. This is followed by a phase of testing and comparing ideas, where the potential of each idea is evaluated. The development of the concept and design of Klu includes the design of the product and its identity, with a focus on user experience and functionality. At this stage, it is extremely important to match the needs of users with technological solutions. Product testing is essential to understand market reactions and adjust the product before its launch. Klu was tested on a small group of users to get feed back and implement the necessary benefits. Launching on the Product Hunt platform, known for promoting new software products, was a key step for Klu. The results show that the key to Klu's success was the careful planning of each step of development, with a focus on market needs and an effective marketing strategy. The paper provides insights into the complexity and importance of each step in the product development process and highlights the importance of adaptability, user experience and modern commercialization.
