Important Role

A chief technology officer (CTO) is one of the most important roles in any tech company. Sometimes the head of engineering, at other times not, the CTO has to be an excellent engineer while also possessing the required skills to communicate complicated technical issues to people from non-technical backgrounds, C-suite executives, for instance.

They must be experts in company policy and procedures and have enough intuition to know which direction the company needs to head.

For a quantum technology company — one of the hardest of deep tech niches — this is more important than ever. Skills in communication, leadership, finance and business development must meld with the technical side of things to create the required dynamism necessary for a successful company.

Realizing it’s usually the CEOs and presidents who get to bask in all the limelight, TQD thought it time to mention those CTOs in the deep and dirty trenches, the people who — in essence — make the startups and companies tick on a day to day basis.

One thing to note, however, is that as usual, this list is non-exhaustive. I have only mentioned those enterprises that actually have the title of CTO as a position in their corporate structure.

Semantics & Diversity Issues

Companies like Google, IBM and other big players, as well as dozens and dozens of QC startups, do — for whatever reason — use different titles such as chief scientific officer (CSO) or chief innovation officer (CIO) etc when applied to positions when the role is similar to that of a CTO in their respective organizations, but semantics aside, the list has been collated to highlight those important people in their CTO roles rather than to cause injury to those not included.

One major disappointment in compiling this list has been the lack of diversity — as expected, white men abound. Women, well, that’s an embarrassing shame, with Elena Blokhina and Prineha Narang being the only representatives on the list.
