It's actually very difficult for African founders to build products that do well in the U.S. We have seen many African founders try to pivot to target the U.S market, and almost all have failed. Why is this, and what are the strategies we can use to enter this market?
First of all, the African market is quite different in that there are lots of gaps to fill. So our product building is on easy mode - almost anything you build will sell, because a) there is little competition at a good price b) you can clearly identify the gaps. The issue is not really selling, it's about how much you can make from the product - it turns out there is a hard cap for almost any idea.
When entering the U.S market, this isn't there. The U.S Americans are innovative, they are smart, they have capital and they know how to build. As a market, it's also not stagnant, people are coming from all over the world and they have different perspectives and so they fill different economic gaps.
This means that the obvious ideas have been tested and someone has filled it, or there is actually no gap there. The non-obvious ideas require domain expertise, and if you are not in America, working within a particular field, it will be hard for you to acquire this expertise.
So how do we solve this? The answer is not to invent anything based on "research", but rather, find someone who has a pressing need. The easiest way to do this is to look on upwork and such platforms - browse through hundreds of listings and try to really get the underlying problem. Avoid problems where the person is guessing at the market, and look for problems where the person is i n an industry and needs something solved.
Once you have identified a few niches, try to find someone in that industry to work with. Without a "deployment partner", you can forget it. You need someone to do on-field testing. Give away equity, do what you need to get this person to co-build with.
After that, niche down on solving ONE persons problem really well. Do not solve theoretical problem, just focus on building something that guy in that industry cannot live without. Once done, try to find a second person and solve for the nuance of what they need. Keep doing this till you are at 10 people, only then do you generalise.
The market is so big that even at 300 customers, you can charge enough and make a pretty good living.
An example: I once built software for a guy who made an app for ringing church bells. The app could be configured to ring church bells at a particular time on a particular schedule, etc. Small idea - but in the U.S it made the guy a millionaire.
The moral of the story: you don't know any industry over there, and you must find a partner who knows this industry. Without this, you are wasting your time.
