Hi, My name is Kyle! 👋🏼

I wear many hats (including the one in my profile picture). Most recently, I've become an early stage venture investor with a focus on deep tech — frontier technology and emerging scientific breakthroughs ready to change the world.

I invest alongside Rand Hindi and contribute to his publication, Deep Tech Deals, if you're interested in our thesis, I recommend subscribing there too.

This newsletter serves as a catch-all for my creative output. You can expect to find:

  • Articles on the Tech Ecosystem, deep-dives on startups or macro trends I find compelling

  • Interviews with founders and investors across Europe (Podcast)

  • Reflections on my journey into venture capital and more specifically what I discover in the realm of deep tech

  • Announcements and updates for events I host or attend, namely, my monthly tech/vc community dinners

👉🏼 More musings from me on Twitter & LinkedIn

For my Anglophone audience, the roi in Startup ROI is a pun.

  1. Return on Investment

  2. Noun. roi m (plural rois, feminine reine) king.

Follow along as I meander my way through the European tech and investing ecosystem ⤵️
