Every day, Global University Venturing rounds up the smaller investments from across the university innovation ecosystem in its deal net.

Voyant Photonics, a US-based miniaturised lidar sensor developer exploiting Columbia University research, has obtained $4.3m in a round backed by the US Department of Defense’s Advanced Research Projects Agency, Contour Venture Partners and LDV Capital. Spun out of Columbia University’s Lipson Nanophotonics Group, Voyant Photonics aims to commercialise a chip-based lidar sensor – a laser-powered detection system based on similar principles to radar – that would be small enough to hold on one fingertip. Voyant’s approach relies on a technique…
