I believe that more than 50% of a SaaS success is in its marketing effort and marketing is very language/culture sensitive. Therefore, it is very reasonable that internationalization shouldn’t be a concern for bootstrapped SaaS businesses. @robwalling was very clear with this point in Microconf 2013 when he said "Don’t internationalize until you max out English / your native market.” I don’t see most bootstrapped SaaS maxing their native markets and internationalization is today a de facto non-issue.
But I still see a missing opportunity here.
With DotNetInvoice and HitTail, @robwalling (sorry man, but you have all the good examples) demonstrated one can be very successful buying a code and being really good in marketing it. Why the same can not be true with licensing?
Licensing is a very standard practice in the conventional software world. I can speak for myself that I would be interested in exploring some SaaS products in the brazilian market. Not all products would suit this case, but I can see many that would work. Still, I don’t know any example of someone licensing a SaaS.
Last weekend, I was talking with @SteveMcLeod about this. Maybe there were too many caipirinhas involved, but we didn’t find any good reason why this is not possible. What you fellow bootstrappers think?
