OpenCorporates is looking for a CTO

Are you a CTO, or do you think you could be one? Are you  looking for a new challenge? Would you like to work in a entreprenurial, fast-growing startup environment which benefits from a proven business model, solid revenues and no debt?

This is an exciting opportunity be a leader within an open data company with a mission to change the world and a compelling commercial proposition.

OpenCorporates is a visionary business mapping the world’s corporate information and uniquely making this available freely as open data. Our innovative commercial model and the considerable social impact of our mission have attracted diverse global customers including the World Bank, the US Treasury, and LinkedIn. Our data is commercially used to support compliance, KYC and business intelligence in scores of  global businesses and by thousands of users of our open service.

Our tiny team has accomplished a huge amount: we’ve mapped over 90 million corporate entities, 21 million business licences, and hundreds of thousands of corporate networks. We measure our considerable social impact annually, and we facilitate use of our data in a wide range of research projects. In recognition of our work, this year we won the Open Data Institute’s Best Open Data Business award.

We are looking for an energetic, UK-based CTO with an entrepreneurial background, who wants to help take OpenCorporates to the next level.

Salary and Benefits

  • Flexible working conditions – both working hours and location
  • Opportunity to co-create a plan to underpin the next phase of our growth and further define our brand and culture
  • £90,000 salary
