The Metrics That Actually Matter | Rule of 40 | Ep. 2
In this episode of Rule of 40, Jason Serda and Josh Ayscough get practical on one of the most important questions for scale-up founders: how do you know if your business is actually heading in the right direction?
They make the case that undisciplined growth is dead. The era of raising capital to paper over execution problems is over, and founders now have one crack at getting it right. Key topics include:
- Burn multiple, net revenue retention, and payback period — the three metrics that matter most and why tracking the direction of travel matters as much as the number itself.
- Why most founders report these metrics without tracking whether they are improving or deteriorating quarter on quarter.
- The rubric: Jason’s defined operating framework that keeps founders executing to a plan rather than managing by instinct.
The episode also goes into bridge funding and what separates a bridge that leads somewhere from one that doesn’t. Specifically:
- What investors are looking for when founders come back to market for a bridge round.
- How to tell the difference between a double shuffle with a clear destination and a delay that amplifies existing problems.
Why more capital into a business with deteriorating metrics makes things worse, not better.
Key Themes
Growth at all costs is over
The 2019 to 2021 playbook of prioritising top-line growth while ignoring unit economics no longer applies. Investors are no longer willing to let broken fundamentals slide if the headline number looks impressive. Intentional growth, where founders understand the impact of every dollar spent, is the new baseline.
Rule of 40 as a compass
Above 40 is healthy. Between 20 and 40 needs clarity. Under 20 is a danger zone. The metric works best as a forward-looking planning tool, not a retrospective scorecard. Founders should model the Rule of 40 impact of their plan before they execute it, not measure it after the fact.
The three metrics that matter most
Burn multiple (spend per dollar of growth: under 1.5 is good, over 3 is a concern), net revenue retention (under 100% means you are on a treadmill), and payback period (under 12 months is strong). Most founders report these numbers without tracking whether they are improving or deteriorating quarter on quarter.
Bridge funding: bridge or plank?
A bridge round should connect a business to a defined destination. If a founder cannot clearly articulate what changes with the bridge capital and how it gets them to a proper raise, it is not a bridge. It is a delay. Investors are stress-testing these plans far more rigorously than they were three years ago.
The valuation premium for discipline
CB Insights data cited in the episode shows Rule of 40 businesses command 9.4 times revenue multiples versus 3.5 times for those below it. The financial case for operating with discipline is clear. The execution is where most companies fall short.
