A focused strategy for legal technology growth.
Sonnet Capital is building a portfolio around the legal sector’s move toward better workflows, stronger knowledge systems, improved delivery, and smarter use of AI.
One sector, not a mandate
Focused on legal technology and adjacent workflow infrastructure.
Involved, not passive
Capital paired with involvement, challenge, and practical support.
Discipline over volume
Backing founders with clear thinking, traction, and discipline.
Built to compound
Durable value creation rather than short-term noise.
Why legal technology
Legal work is shifting from being organised around individual expertise to being organised around systems: how matters are captured and assigned, how prior work product and precedent are found and reused, and how AI is applied to the delivery of legal services rather than bolted on around the edges. That shift creates room for category-relevant companies with real operating substance — not point solutions that stall once the first wave of interest fades.
We look for founders with clear domain insight, useful products, and the ambition to build something that matters. We do not take a passive view. We support portfolio companies with commercial thinking, strategic challenge, operating structure, partnership development, and access to practical growth support.
