Operator-ledcapitalforinnovationinlegalandregulatorytech
We invest in founders building transformative products for the legal ecosystem and adjacent regulated markets. By making a handful of high‑conviction investments each year, we roll up our sleeves and concentrate our time, network, and operational know‑how where it can move the needle the most.
