Karpel Solutions builds case and matter management software for the people who run the justice system: prosecutors, public defenders, city attorneys, and municipal courts, across criminal and civil matters. Our flagship product, PROSECUTORbyKarpel (PbK), is the most widely used prosecutor case management system in the United States, serving more than 800 offices across 36 states, from four-attorney city offices to statewide deployments. DEFENDERbyKarpel (DbK) gives public defender offices the same capabilities, built around the needs of the defense. MUNICIPALbyKarpel brings the platform to city attorneys and municipal courts, where criminal prosecution and civil matter management live in the same office. Every product is designed with the practitioners who use it. KAi, our proprietary AI assistant built into every Karpel product, lets attorneys and staff ask a plain-language question and get an answer grounded in their own case data, with the supporting records shown, so the office spends less time searching and more time on casework. Around it: paperless case and matter files, document generation, in-court use, eDiscovery, evidence tracking, victim services and VOCA reporting, and integrations with courts, law enforcement RMS, Evidence.com, Westlaw, email, and calendar. Everything is delivered as SaaS, hosted in a secure, CJIS-compliant environment, so offices never run their own servers. Karpel has served the public sector since 1995 and is headquartered in St. Louis, Missouri. We are a portfolio company of Thompson Street Capital Partners and an eight-time Inc. 5000 honoree. If your office is still managing criminal cases or civil matters from paper, spreadsheets, or a system nobody supports anymore, we would like to show you what a purpose-built, AI-enabled system looks like.
