Arpit Gupta, Naveen Sharma, and Vikram Deswal co-founded the mobile payment app UnDosTres in Mexico City in 2015. In the past, Gupta had worked at Paytm, an India-based payment app valued at over $1 billion. In Mexico, the co-founders hoped to recreate Paytm's success. The co-founders quickly learned that in Mexico, the Paytm playbook could only get them so far. To grow UnDosTres, they needed to think fast and adapt to Mexico's unique business environment.
