Now the cofounder and CEO of Glovo, an app-based on demand courier service, manages 1,500 employees in 26 countries, half of them in his hometown Barcelona where the company has its headquarters.
"I was looking for another rhythm," the slim former aeronautical engineer, who comes from a family of entrepreneurs, told AFP, explaining he found the aeronautics industry "a bit slow".
At the entrance to Glovo's headquarters there are several yellow backpacks used by the firm's 50,000 drivers to deliver restaurant meals by bicycle or motorcycle to people's homes in 288 cities around the world as well as diapers, medicine, flowers and other goods.
Because unlike its rivals Deliveroo and UberEats, Glovo does not just deliver food. "Order what you want," the app tells its customers.
Glovo is on track to rack up 250 million euros ($277 million) in sales this year, Pierre said, a 200 percent jump over 2018 when sales already recorded a 350 percent jump over the previous year.
Since it was founded in 2015 the company has raised 460 million euros from investors, and it recently achieved the status of a "unicorn" - a start-up valued over $1 billion.
"It makes you dizzy, it's a lot of pressure, but at the same time we make the most of it because we know that it is unique to live this," said Pierre at Glovo's headquarters which features beanbags and table football for employees.
Glovo is already making money in Spain, Italy and Portugal and Pierre expects the company as a whole will be profitable "within 18 months".
The company's strategy involves focusing on areas where it faces less competition than in western Europe such as Latin America, Ukraine, Morocco and the Ivory Coast.
It wants to speed up delivery times using algorithms cooked up by hundreds of engineers and to do this Glovo plans to hire 300 new staff for its IT team in 2020.
"We have to choose a machine learning model that is able to estimate how long an order is gonna take to prepare and then only tell the courier to arrive at the location as quickly as possible, at the same time as when the order is ready to be picked up," said Mustafa Sezgin, the head of the company's IT division.
