While reading some stuff recently I’ve found an article by Steve Blank (the author of The Four Steps to the Epiphany), a huge list of tools that are helpful for any entrepreneur. Obviously, not all of them, but you will surely find out one tool that is interesting for you.
The categories are: Startup Tools, Founding/Running a Startup Advice, Market Research, China Market. Or, subcategories: Getting Started, Tools from Others, Groups, Find a Co-Founder, Business Model Canvas/Customer Development Tools, Business Models, Customer Development, Customer Discovery Checklist, Founder Stories, Website Domain Names… and about 30 more.
Finally, here is the link, stop complaining :) It’s one big list, just know this. And, more important, it’s written in 2009 (base on the comments), so if some tools are not available, do not kill the messenger.
