What is T2D3?
T2D3 is a SaaS growth path: triple, triple, double, double, double. Starting from product-market fit, annual recurring revenue triples for two years, then doubles for the next three.
It became a benchmark for what elite growth looks like. Popularized by Bessemer Venture Partners, it describes the trajectory of companies racing from a few million in ARR toward 100 million.
The T2D3 math.
Each year multiplies ARR by the next figure in the sequence: 3, 3, 2, 2, 2. Compounded, that is a 72-fold increase over five years.
This tool applies the path to your starting ARR and shows each year. Enter where you are today, and it projects the full five-year sequence.
A worked example.
Starting from 1,000,000 in ARR, the path runs 3,000,000, then 9,000,000, 18,000,000, 36,000,000, and 72,000,000 by year five. That is the 72x the sequence implies.
Is T2D3 realistic?
For most companies, no, and that is the point. It describes elite hypergrowth, not a typical or expected trajectory, so very few SaaS businesses actually hit every step.
The projection assumes growth keeps compounding, which only happens with a durable acquisition engine. Reading it against the new ARR it should produce grounds the target in the actual additions each year demands.
How to pursue it.
Hitting any part of the path takes a repeatable, scalable way to add ARR, since tripling once is hard and doing it twice is rare. The growth has to come from channels that scale without costs scaling just as fast.
Organic search is one of the few channels that compounds with growth rather than recurring per deal, which supports growth that does not rely on paid.
