What will it take to switch.

Why does he need anyone to switch? This competitor has just launched their product. That means they have very few users and almost no brand recognition. 99.9% of the world will have no idea who launched first and won't care.

You don't need to convince anyone to switch from your competitor's product. You just need to convince people to use your product, which is a problem you already had. In that sense, the launch of a competing product shouldn't affect your roadmap at all.

Longer term, you should be worried about the huge imbalance in resources. That's solvable, though: if you get any traction with your product you can raise funds and hire a team.
