Overview
Parthenon is a constituent relationship management and communications platform for elected officials, available on Android, iOS, and web. Its Reach product sends newsletters, alerts, press releases, and SMS from one platform. Nexus brings constituent records, messaging, an inbox, and casework management together. Its Outlook add-in can validate constituent residency, generate AI-enabled responses, and summarize past interactions; the add-in is approved for Microsoft 365. Nexus also includes a mobile app for capturing constituent interactions in the field in real time. Parthenon lists city councils, county commissions, school boards, state legislatures, and U.S. Congress among its customers. The cloud service has no free plan and offers a 14-day trial. Reach plans begin at 19.00 USD per month, billed monthly, for up to 1,000 contacts and one user license; a .gov email is required. SMS is a paid add-on with platform fees and usage-based credits, and sending requires registering a 10DLC number with the FCC. Parthenon Labs says it is SOC 2 Type 2 certified; Nexus states that customer data is hosted in the United States and remains government-owned.
