Our Story
Halley AI was founded on a bold premise: every answer and every insight should arrive in the time it takes to blink. After decades engineering fail-safe systems for healthcare, aerospace, logistics, and enterprise technology, our founders saw two stubborn constraints — support queues packed with repeat questions, and analysts drowning in raw data.
We fused cutting-edge large-language-model research with enterprise-grade controls to create a dual engine: AI Assistants that resolve customer queries instantly, and AI Data Analysts that transform siloed information into on-demand dashboards. Together they remove friction from the front line and the back office, letting teams focus on deep work instead of busy work.
Named after Halley's Comet — predictable, powerful, and always on schedule — we bring that same certainty to every interaction. Today, leading organizations rely on Halley AI to delight users, surface trends, and accelerate growth — 24/7 · 365.

One company behind all of it.
Halley AI is an ESX, Inc. brand — one of three products ESX builds in house. ESX started in Houston in 2001 with one conviction: associations and mission-driven organizations deserve software as ambitious as their missions. It has never been acquired, and the people who build the platform own the company that makes it.
The system of record for membership, events, continuing education, community, and fundraising. One member record, every touchpoint, with AI copilots built in.
Grounded in your data, not the internet. Halley answers from your own connected sources and shows where each answer came from — which is what makes it usable in regulated, data-sensitive work. It powers the copilots inside xCatalyst and ships as its own platform.
AI-first support operations. Nova turns noisy inbound across email, tickets, and chat into structured context, so every request gets a clear place to land. Nova proposes the next step and the owner; your team decides.
