      # Hi, I'm Michael
      <Spacer />
      I co-founded <a class="hover:underline" href="https://snips.ai" target="_blank">Snips</a>, building privacy-respecting voice recognition technology. We got acquired by Sonos in November 2019. Prior to that, I created <a class="hover:underline" href="https://www.youtube.com/watch?v=q3OuCR0EpGo" target="_blank">8pen</a>, a new way to write on mobile devices which draws inspiration from handwriting.

        Whenever we have an idea or want to take a note, we reach out for pen and paper. It is often the fastest and easiest way take a note. We enjoy handwriting, because it is natural. So one may ask: *is there a natural way to write on small devices?*
