The hypergrowth trajectory
T2D3 describes an aspirational SaaS growth path, triple revenue for two years, then double for three, taking a company from a few million to over one hundred million in ARR. The name spells out the pattern: triple, triple, double, double, double. Starting around two million in ARR, a company following this trajectory reaches nine digits in roughly five years. It captures the growth shape of some of the most successful SaaS companies ever built, and it has become shorthand for what hypergrowth looks like.Aspiration, not standard
The essential caveat is that T2D3 is elite, not typical:
- It describes category-defining companies, not the median SaaS business. - Most companies never triple even once, let alone twice. - Treating it as an expectation rather than an aspiration sets a bar almost everyone misses.
Used as a reference for what is possible at the extreme, T2D3 is illuminating; used as a target every company should hit, it is discouraging and misleading, because the trajectory belongs to a rare few.
What it teaches
Beyond the specific numbers, T2D3 illustrates two real dynamics. First, compounding at high rates produces staggering scale quickly, which is why growth rate matters so much to valuation and to the Rule of 40. Second, growth naturally decelerates as a company scales, the pattern moves from tripling to doubling because maintaining a growth rate gets harder as the base grows, which is an honest reflection of how even the best companies slow down in percentage terms. Sustaining a trajectory anywhere near T2D3 requires exceptional net new ARR generation and strong net revenue retention, since a leaky base makes such compounding impossible. T2D3 is best understood as a vivid picture of what elite SaaS growth looks like and how compounding drives scale, rather than a benchmark to measure an ordinary company against, and keeping that distinction clear is what makes it useful rather than demoralizing.
Frequently Asked Questions
What is T2D3?
T2D3 stands for triple, triple, double, double, double, a growth path where a SaaS company triples its revenue for two consecutive years and then doubles it for three. Starting from roughly two million in ARR, this trajectory reaches over one hundred million in about five years. It describes the growth pattern of some of the most successful SaaS companies.
Is T2D3 a realistic target?
For most companies, no. T2D3 describes the trajectory of elite, category-defining SaaS companies, not a typical or expected path. It is an aspirational benchmark that illustrates what hypergrowth looks like, useful as a reference for what is possible, but treating it as a standard would set unrealistic expectations for the vast majority of companies.
Why is T2D3 a useful concept?
Because it gives a concrete shape to hypergrowth and shows how compounding at high rates produces enormous scale quickly. It also illustrates that growth rate naturally decelerates as a company scales, from tripling to doubling, which is a realistic pattern even for the best companies. It frames what elite growth looks like without pretending it is common.
