Before using and reading the method, take an oath - "I will not use this as spam, I will conduct interviews, not run around random contacts like a traveling salesman and push my product."

The method is especially suitable for technology startups. Open the specialized Google search for articles and patents and use your imagination in searching - enter your product, area of work, problem, equipment names your product works with, etc. The main thing is to try to work narrowly, not just enter "Oil production". Collect relevant articles, go to them and look at the authors and the organization on behalf of which the article was published. Write to the author that you saw the article and want to get feedback on your product that works in the same industry.

What this gives - a large pool of contacts, experts from scientific circles who will give feedback on your product both in terms of applicability and from a scientific point of view on technologies. They will share with you contacts of many people from the industry working in this field.
