If your product is something that market already demands, one idea is to set up a site and run a small ad campaign. "How to Kill a Startup Idea with Google Keyword Planner and AdWords: A Case Study" https://www.psl.com/feed-posts/psl-studio-kill-xylo https://www.psl.com/feed-posts/psl-studio-kill-xylo Earlier HN discussion: https://news.ycombinator.com/item?id=22110004 https://news.ycombinator.com/item?id=22110004 I also recommend Rob Walling's book Start Small Stay Small. https://startupbook.net/ https://startupbook.net/ The book is mostly a practical marketing guide written for developers who are trying to bootstrap a business.

Then, before building product, run experiment to validate or reject your product idea based on market demand & estimated conversion.
