Seat Expansion
Growth in subscription revenue driven by an existing customer adding more user seats over time, rather than by acquiring a new account.
How Seat Expansion works in practice
Seat expansion is one of the cleanest forms of SaaS growth because it comes from existing customers getting more value and broadening usage. It usually signals healthy adoption inside an account, especially in collaboration products where team spread is part of product-market fit. From a unit economics perspective, seat expansion is attractive because the acquisition cost for those additional seats is near zero compared to winning a new customer. Products designed for shared workflows often build much of their NRR on this lever.
