About us

Our vision is to see tech city ecosystems driven sustainably, economically and inclusively to solve the grand challenges of our time. 

Founded by George Johnston and building ventures alongside world-class co-founders, we acknowledge that one company alone cannot create real impact.

Tech City Ventures is a growing collective of firms, each with its value proposition, dedicated to fostering city tech ecosystems. 

In little under 4 years we have developed a team of 50+ talented individuals who have worked with over 30+ clients, 200+ high growth scale ups, 300+ executives and delivered many successful private-public sector partnerships.

  TCV is focused on two key goals.

Goal 1

To help our cities sit at the heart of technology ecosystems

Goal 2

To build and scale solutions inclusively and collaboratively

Together we collectively offer the skills and tools to take ideas to impact and help solve the grand challenges of our time.
