ESX builds software for associations and the organizations that run them. We have been at it since 2001, from Houston, Texas, and we are employee-owned. Associations run on a dozen disconnected tools. We build the alternative: one member record, one finance ledger, one AI layer, and the software around them. Three products: xCatalyst™ — the all-in-one association platform. Membership, events, learning and CE, community, fundraising, and the public website, in one system. Halley AI™ — applied AI on your own data. Source-linked answers, operational insights, and AI-guided intake, with a focus on regulated workflows. Nova's Desk™ — AI-first support operations. Every request gets a clear place to land. The AI in our products proposes; people decide. Answers cite the customer's own data, data boundaries are controlled, and nothing trains on customer content. ESX, Inc. — Houston, TX. Employee-owned since 2001.
