Your case sounds ideal for Founders Squad
"Every month, we hold structured, founders-only meetings where we take turns at addressing our most challenging business situations together. We share what we have learned from each other’s priceless experiences. We take the time to dig to the root and identify the right questions – before finding the right solutions and decisions. Together, we help each other in a non-judgmental environment that fosters unparalleled trust and collaboration.
I haven't had the pleasure of attending a meeting yet myself, but it sounds like just the support circle you need
And they happen to meet at the offices of a highly regarded firm, Pamir Law run by Nicolas Chen https://linkedin.com/in/nicholasvchen
(Nick and Pamir were key supporters of my friend Christine Hsu and major stakeholders in ORIENTED after Chris and I went separate ways in 2002. You may already know that Chris and I founded a website called ORIENTED.org in 1998 - she kept the name and I kept the website that I ultimately renamed to Forumosa.com)
And, of course, there is Elias Ek of Enspyre.com - Elias literally wrote the book on starting up in Taiwan http://www.startabusinessintaiwan.tw/
So I would reach out to him for, at least, general advice.
It was Elias who once explained to me that the French Chamber of Commerce http://www.ccift.org.tw/services-in-taiwan/set-up-in-taiwan/ (used to?) specifically focus on small businesses. So, whether or not you are French, it will likely pay off for you to schmooze with some of the people who attend or organize those events
I did a quick search for a MasterMind Group in Taiwan. I only found some posts on Reddit from a year ago of people also looking to form such groups. If you do wind up joining or starting one, please remember to post about it here in Forumosa.
And, finally, if I were in your position in Taipei, I would be on the look out fellow entrepreneurs who set up in any of the incubators or co-working spaces supported by angel investors around the city. I know a few, so PM me if you want me to introduce you -- take note that the guys I know tend to be in IT related fields, not food tech or manufacturing. Nevertheless, it may be useful to network with them, take them out for a cup of coffee in exchange for some war stories.
