About me

I am an investor, technologist and former research scientist. I work with companies that solve challenging and valuable problems using breakthrough technologies including, but not limited to, artificial intelligence.

I was previously a Partner at Playfair Capital, where I sourced, led and managed venture investments in 33 technology companies across the US and Europe including Mapillary, Numerai, Ravelin, Dojo, Lystable, Gluru, Onfleet, Festicket, Trouva, Appear Here, Starship Technologies, Thought Machine and Jukedeck. I was responsible for setting our investment strategy, diligence and operating process, brand positioning, portfolio community relations and the firm's marketing.

I led our thesis of investing in artificial intelligence and other breakthrough technologies that solve valuable problems to create category leading companies. I set up the annual Research and Applied AI Summit in 2015 and have run it twice with 300 attendees and 12 speakers in 2015 and 2016. I also co-run the London.AI meetup. Both forums unite leading academics, entrepreneurs, engineers, investors and thought leaders working in the field to accelerate the future of AI.

Prior to Playfair, I earned an M.Phil and Ph.D. in computational and experimental cancer research as a Gates and Dr. Herchel Smith Scholar at the University of Cambridge, and a BA in biology from Williams College. I've published research that leverages both experimental and computational approaches to understand how we might stem the fatal spread of cancer around the body.

Thoughts on technology, VC and company building

I write and speak about about market trends in the technology and venture capital industry, new companies I invest in and learnings as and when they happen. Here are some highlights:

  • Artificial intelligence and machine learning
  • Health and life sciences

  • Investing and building a company

    I also tweet sometimes from @nathanbenaich.
