KAS Venture Partners
About KAS Venture Partners
KAS Venture Partners is a family office operating as a generalist VC. The firm co-led Hadrian's Series B and has backed companies including Groq, viaPhoton, Boom Supersonic, Recess, Aalo Atomics, Atomic Industries, and many others. We invest across various industries including next-gen manufacturing, AI infrastructure, energy, and logistics, supporting founders through multiple rounds and gravitating toward companies building in the physical world.
KAS Venture Partners is described as the venture vehicle of Kevin Ulrich, co-founder and former CEO of Anchorage Capital Group, a New York alternative credit manager. Crunchbase lists Ulrich as the founder. Tracxn dates the firm to 2022, but the firm does not publish a founding year on its own site. One investor database lists Ulrich as Founder and CEO, Julian Handel as Partner, and Lucas Lorentz on the team. The firm has not published fund names or fund sizes, so none are given here. It does not publish a separate AI team or named AI lead.
KAS does not publish an AI thesis. Its AI activity is mostly in physical AI and AI-enabled manufacturing, where software, hardware and industrial deployment meet. In 2026 it took part in two large rounds of this kind. Walden Robotics launched from stealth with a $300 million seed round to build general-purpose robots that keep learning while they work in manufacturing and logistics. Atomic Machines emerged with $250 million raised to date for an AI-native manufacturing platform. In both rounds KAS was one of several named investors. The reports reviewed do not name it as lead.
The firm publishes no stage focus and no check-size range. Its recent public activity includes a $300 million seed round (Walden Robotics, July 2026) and a $250 million venture round (Atomic Machines, October 2026). Round size is not the same as KAS's own cheque, and no investor allocations were disclosed in these rounds. Founders should treat check size as something to ask about directly.
