Ziqitza Healthcare Ltd is an ambulance service provider in India that was invested in by Acumen over five years ago. It has since grown from 9 ambulances in Mumbai to over 1,000 ambulances serving 2.5 million callers across 5 states.

This case study will walk through how Ziqitza used a Lean Data approach to gather new customer insights without disrupting operations or hiring external surveyors.
