Where Growth Comes From Past $20 Million ARR
Expansion revenue, growth pulled from an existing customer base rather than new logos, becomes the dominant growth engine for a SaaS company somewhere beyond roughly $20 million ARR, per benchmark research originally published by OpenView and now continued under High Alpha. Companies over $50 million ARR take that further, generating roughly 60% of their new ARR from existing customers. Net revenue retention above 110% is described in the same research as the single strongest predictor of a SaaS company’s valuation, ahead of growth rate measured on net-new logos alone.
This figure is cited here through secondary coverage rather than an independent, line-by-line read of the current report, and the underlying research program’s ownership itself changed hands during the period this document covers, from OpenView to High Alpha. Both facts are worth naming plainly given how much a stats page implies precision.
The Gap Between Average and Top-Quartile Expansion Programs
The average SaaS company generates expansion revenue equal to roughly 12% of its starting ARR annually. Top-quartile companies generate 28%, a 16-point gap the same research attributes to systematic, deliberately built expansion programs rather than ad-hoc upselling left to individual account managers. That gap is a program-design difference, not simply a product-quality one.
A confirmed, independently sourced figure backs the same underlying pattern without relying on the ownership-transition caveat above. SaaS Capital’s 2026 survey of more than 1,000 private B2B SaaS companies found companies with net revenue retention of 120% or higher carry a median annual contract value of $61,802, more than double the $26,269 median for companies below that retention line, direct evidence that a well-retained, well-expanded account is worth meaningfully more than one that is not.
