How to deal with rapid growth and aggressive expansion when your development team is not big enough?

Executive Summary

BlaBlaCar wanted to expand quickly to 27 markets around the globe but needed to extend their development teams to achieve this goal. While building their second development center in Warsaw, Christian Jennewein, Head of Engineering at BlaBlaCar decided to turn to XSolve to save on time. XSolve provided a self-organizing remote development team, which became a seamless part of the BlaBlaCar operation for a year and a half. BlaBlaCar continued to recruit, train and build their in-house Warsaw team while successfully gaining dominance in the targeted markets.

BlaBlaCar wished to share their carpooling journey with us, and we gladly joined this ride. XSolve was compatible with BlaBlaCar not only in the aspect of technology but also in terms of organizational culture, values, and cooperation practice.

Christian Jennewein

Head of Engineering at BlaBlaCar


BlaBlaCar, a unicorn startup from Paris, is one of the most successful tech companies in Europe, connecting drivers who have empty seats in their cars with passengers who want to travel to the same destination.

The client is experiencing a rapid growth and their in-house team is not enough.

• BlaBlaCar approached XSolve, looking for help with their next stage of rapid growth.

• They wanted to expand quickly into 27 markets around the world, gaining a competitive advantage over other travel/carpooling app contenders.

• BlaBlaCar needed an agile, self-organizing development team to start working on the new features necessary to make the app truly competitive.

• BlaBlaCar chose Warsaw as their second development hub. They knew that it would take time build their new Poland-based development team: time to recruit, time to onboard and train, time to form a high-performing team with all the skills necessary.

• Despite substantial financial resources, time was the one thing they didn’t have if they wanted to become the leading provider in their chosen geographical regions.

• While recruiting the developers for their Warsaw office, they decided to turn to outsourcing in order not to waste time.
