Nonlinear Growth
Definition
Nonlinear growth is an increase in output, revenue, or users that accelerates rather than adding a fixed amount each period, often driven by compounding effects like network effects or referral loops.
How it comes up in fundraising
Investors get excited by evidence of nonlinear growth because it suggests a business can compound without proportionally more spend, unlike linear growth that scales only as fast as sales and marketing spend does.
Frequently asked questions
What causes nonlinear growth?
Network effects, viral loops, word-of-mouth, and compounding retention are the most common drivers, since each new user or dollar makes the next one easier to get.
How do investors distinguish nonlinear growth from a temporary spike?
By checking whether the acceleration holds across multiple cohorts and periods, rather than one unusual month driven by a single campaign or press hit.
