It very much depends on what the start up is. You need to know your customers, what they want/need and how much they are willing to pay. You also need to know your competition and what they are doing, and how much they charge. Then you need to make sure that you make your potential customers aware of your business with your unique proposition. The strategy and tools you use to create awareness of your business depends on your customers. You can measure the number of actual and potential customers, and you can calculate the cost of your promotional strategies. At first, they are not likely to create profit but if you manage to create good word of mouth, good reviews and satisfied customers you should soon move from investment to break-even to profit.

Methodological pluralism, or the use of multiple methods in research, can be a useful approach when investigating complex and interdisciplinary topics such as law and philosophy. By using a variety of methods, researchers can gain a more comprehensive understanding of the subject matter and potentially uncover new insights and perspectives.

In your case, exploring the possibility of a method for elaborating a radical thinking of law and the consequences of the existence or not of a research method can benefit from methodological pluralism. This approach can involve using a range of research methods, such as qualitative interviews, case studies, and critical analysis of existing literature, to answer your research questions from multiple angles and perspectives.

However, it is important to consider the potential challenges and limitations of using multiple methods, such as the increased time and resources required, and the potential for conflicting or inconclusive results. To address these challenges, it may be useful to carefully select and integrate the methods used and to critically reflect on the strengths and weaknesses of each approach.

Overall, methodological pluralism can be a valuable approach to consider when conducting interdisciplinary research and investigating complex and multifaceted topics such as law and philosophy.
