Welcome Pickups is a taxi service for travelers that handles 1500 rides a day across 50 destinations. To increase revenue, I was making continuous data-driven improvements to its booking site, which was the main source of customers. After around 20 experiments and a complete redesign, the conversion rate and revenue increased by a double-digit percentage, while support costs dropped by a similar amount. A key factor in these results was close collaboration with product managers, developers, and support agents to identify problems, develop ideas, run experiments, and ultimately deliver the final product.
