Curious how a cleaning company (Hogaru) basically identical to Homejoy that shut down and failed can simply focus on another market (country) and still get into YC? If it doesn't work in the US (arguably the best market in the world), what conditions make it more likely to succeed in South America? FYI, I spent 2 months in Chile as a digital nomad, and quite honestly most people in South America don't have a lot of disposable income. House cleaning is definitely a luxury item there, way less common than the US. There is also a German startup Helpling doing the exact thing for the German market (which in my opinion is a better market). https://www.helpling.de https://www.helpling.de
