T2D3 stands for Triple, Triple, Double, Double, Double — a shorthand for the revenue growth trajectory that takes a SaaS company from $1–2M ARR to $100M+ ARR over five years.
The math behind T2D3
Starting from $2M ARR:
| Year | Multiple | ARR |
|---|---|---|
| 1 | 3× | $6M |
| 2 | 3× | $18M |
| 3 | 2× | $36M |
| 4 | 2× | $72M |
| 5 | 2× | $144M |
This translates to roughly 200% YoY growth in years 1–2 and 100% YoY growth in years 3–5.
Is T2D3 realistic?
For venture-backed SaaS with significant GTM investment, yes — T2D3 represents the expected return on institutional capital. For bootstrapped or self-funded businesses, these multiples are exceptional outliers.
T2D3 assumes you've found product-market fit, have a repeatable GTM motion, and can invest aggressively in sales and marketing. It's a target, not a guarantee.
How to use T2D3 as a planning tool
Break the annual multiple into monthly targets. Tripling means growing ~10.5% MoM (since 1.105^12 ≈ 3.0). Doubling means ~5.9% MoM. If your MoM rate is consistently below these thresholds, investigate whether the GTM motion needs repair before scaling spend.
