Zubale, founded in Mexico City by two HBS grads, just raised $4.4 million to put locals to work over their phones

One that stood out to us at the time was Zubale, a Mexico City-based outfit whose founders were looking to connect big corporations with Latin Americans eager to address tasks on their behalf. A person could conduct on-the-ground market research for a brand, for example, then earn mobile phone credits or other redeemable digital rewards. First, according to Zubale co-founder Allison Campbell, the retail industry across Latin America is generating $2 trillion per year, but companies are also shelling out $40 billion on "super painful and high spend" that includes employees who complete in-store tasks like stocking shelves, checking prices and building displays.
