SaaS metrics guides.
Lightbridge.ai publishes these SaaS metrics guides as an independent reference for founders, finance leaders, and revenue operations teams. Each one defines a growth or efficiency metric in plain language, gives the formula, and flags where the definition varies, so a board conversation runs on shared numbers rather than guesses.
Every guide is written by senior Lightbridge.ai practitioners, most with two decades of experience in industry and consulting, and grounded in hands-on enterprise engagements since 2017.

Read the guide →Lightbridge.ai defines SaaS metrics without a billing platform to sell.
Most SaaS metric explainers are published by billing and analytics vendors whose definitions tilt toward what their product measures. Lightbridge.ai is an independent technology advisory group, so these guides describe the conventions as the market actually uses them and name where definitions genuinely diverge. The metrics here are SaaS-finance conventions, not accounting standards.
The revenue these metrics measure is recognized under accounting standards that Lightbridge ERP covers directly: ASC 606 revenue recognition, deferred revenue, and subscription billing models. For the systems that produce these numbers reliably at scale, the Lightbridge.ai advisory practice guides the selection.
From metric definitions to a system that produces them.
When the numbers need to come out of real systems rather than spreadsheets, Lightbridge.ai advises on the finance and revenue platforms that produce them.
