If I were a VC I would invest huge in Mexico City talent development. Far more under-trained talent there and same time zone so remote from MC is temporally seamless.
From my experience, it's actually kind of easy to find English speakers here. That's why a lot of US-based tech companies are opening up teams here or recruiting people from here. The government's uncertainty has not affected business for this particular case.
Border town developer here. Indeed, there's a ton of talent in Mexico's border towns (specially in Mexicali and Tijuana), highly qualified and with decent bilingual skills.
