What we're building
Focused products for AI data infrastructure and cost intelligence.
The engineering foundation behind our enterprise data work is going into focused products of our own — starting with AI-native data infrastructure and LLM cost intelligence.
LLMRates.ai
LIVEAI model pricing and cost intelligence for developers and teams. Compare pricing across 1200+ models from major AI providers and forecast real-world LLM costs in one place.
LongData.ai
IN DEVELOPMENTAn AI-native data engineering platform that helps enterprises turn natural language, business semantics, and data contracts into reliable, auditable data pipelines — with every output validated before it reaches your database.
bayhub.hk
PUBLIC BENEFITA public-benefit knowledge hub, bayhub.hk, for growing a business in Hong Kong and the Greater Bay Area — and expanding from there to global markets. We use AI to continuously gather and organize market intelligence, funding programs, and cross-border operations guidance from across the web — no tracking, no login walls, openly licensed.
From commercial products to a public-benefit initiative — all built on a foundation of real data engineering.
AI-native infrastructure
Engineering the data foundation for AI
We turn messy, real-world enterprise data into reliable, production-ready systems — the unglamorous groundwork that makes AI actually work.

The engineering foundation behind every product we build.
Our products are built on 20+ years of hands-on work in enterprise data systems — from architecture and pipelines to production software and LLM integration.
Enterprise data engineering
Architecture, pipelines, and governance for real-world data systems.
AI-native software development
Full-stack products with purpose-built agent harnesses that put LLMs and agentic AI to work in practical workflows.
Cost, quality & reliability systems
Tools that help teams measure, control, and improve the cost, quality, and reliability of their AI.
Business semantics & data contracts
Turning business meaning into structured, verifiable data workflows.
Who we are
A founder-led data and AI product company.
Longinfo Technology Inc. (Longinfo.ai) is a founder-led data and AI product company based in Hong Kong. Through years of enterprise data consulting, we have served clients across the United States, Canada, and China — including many Global 500 and Fortune 1000 companies.
That work gave us deep, hands-on experience in the hard, unglamorous work of both messy data engineering and making AI genuinely useful: messy data, fragile pipelines, unclear costs, inconsistent business semantics, and the gap between AI demos and production systems. Every product we build is shaped by real problems we have solved for demanding enterprise clients.
We work with clients worldwide, delivering real-world AI software products that actually make it into production for developers, teams, and enterprises.
