Uber Freight co-founders Charlie Bergevin and Brian Cristol have left for Turvo, a venture-funded collaborative logistics platform. : Last year, Charlie Bergevin and Brian Cristol, co-founders of Uber’s trucking logistics business Uber Freight, heard Reid Hoffman say Turvo had some of the best technology he had ever seen. Frustrated with the direction Uber Freight had taken, they called up Turvo’s founder and chief executive officer Eric Gilmore. It wasn’t long before offers were on the table and now, they’ve joined Turvo full-time. Cristol as head of enterprise partnerships and Bergevin as an enterprise partnerships executive.
