How to examine a startup's traction evidence
The guide separates registrations, active usage, pilots, signed commitments, reported revenue and cash received. A fictional cohort example shows how customer retention and recurring-amount retention answer different questions.
What you will practice
Define a metric in plain language. Preserve its calculation and denominator. Follow a starting cohort without mixing in newly acquired customers. Identify a methodology change and explain what a public-source review cannot verify.
No universal customer count or growth threshold is presented as proof of product-market fit.
Choose your perspective
For experts: connect a commercial conclusion to the definition, period and evidence that support it.
For readers: distinguish the business relationship described by a metric from the stronger relationship you might be tempted to infer.
Continue the learning path
Use general method to connect commercial evidence to a broader research question. The NVIDIA filing case provides a dated public-company exercise in reading reported financial figures, while preserving the difference from private-startup disclosures.
