40% of Your Revenue Is Likely Toxic
(And You’re About to Scale It)
Introduction
Next week in Lecture 9, we’ll explore Stage 9: Repeatability—the first stage of the Go-to-Market Fit phase. But before we get there, there’s something critical that needs to be addressed.
The space between completing Product Market Fit and entering Go-to-Market Fit isn’t a stepping stone. It’s a chasm.
And most startups fall into it.
The Mistake Most Founders Make
Here’s what typically happens: a startup completes the four stages of PMF—they’ve acquired design partners, proven usage, demonstrated value, and captured fair pricing. Revenue is coming in. Investors are happy. The team is excited.
The natural instinct is to hit the gas. Raise the Series A. Hire the sales team. Scale what’s working.
Want to know whether you have Product Market Fit?
RVNU has a developed a GTM Debt Assessment tool, that highlight your stage of growth and details the jobs to be done in order to achieve product market fit.

But here’s the problem: what you think is working often isn’t. Or more precisely, it’s working in a way that won’t scale.
In 100s of conversations with founders annually, the pattern is frighteningly consistent. The revenue in the PMF phase came from approximately 10 design partner clients (if we’re talking enterprise B2B). When we analyze the cohort data, we typically find that only 60% of those clients actually met the refined ICP threshold, delivered the expected value exchange, and justified the unit economics needed for sustainable growth.
The other 40% are vanity revenue.
The Data Doesn’t Lie
At Maxymiser, we had a stark example of this pattern. The initial bottom-up strategy saw us acquiring non-ICPs, overpromising to get small deals done, and selling too low in organizations without putting buyers under pressure to measure value back to us.
We were generating revenue. Money was coming in. But the churn was brutal. The revenue wasn’t sustaining, and the GTM strategy was failing rapidly.
The fundamental problem: we were celebrating revenue that was actively destroying the business. This is very common in startups, still today.
Once we adjusted our messaging and value proposition, offered white glove onboarding, and sold both top-down to economic buyers and bottom-up to end users in marketing—ensuring both sides were aligned on value measurement—our ACV increased 10x, our net logo retention went from <50% to >90% and our net revenue retention (NRR) went from <50% to >120%.
That adjustment—that realignment based on what we’d learned about who actually valued our product and how to prove that value—became the foundation for everything that followed, including our eventual exit to Oracle.
Why Going Backwards Isn’t Slowing Down
In SaaS, we talk constantly about pivoting or persevering. But there’s a third option that rarely gets discussed: realign and relaunch.
This isn’t about questioning your fundamental business model. It’s about using the rich data gathered during the PMF phase to tighten your ICP, refine your messaging, adjust your pricing model, and eliminate the clients and strategies that will create drag as you scale.
Think of it this way: if you complete PMF with 10 clients and 40% of them don’t meet your refined success criteria, you’re about to spend Series A capital acquiring and servicing more of the wrong customers. That 40% compounds. It becomes 40% of your sales team’s time. 40% of your CS team’s bandwidth. 40% of your churn rate.
Or worse, you institutionalize it by hiring transactional sales reps who can only sell to that lower-value segment, and you’ve just locked in a business model that will never achieve venture-scale returns.
The Efficient Growth Chasm
The transition from PMF to GTM Fit is what I call the “efficient growth chasm.”
It’s the point where founders must choose: rush forward with incomplete validation and accumulate compounding GTM debt, or take a temporary step backwards to realign around the optimal opportunity revealed by their PMF data.
Most founders, under pressure from investors and peers, choose to rush forward. They see going backwards as slowing down, falling behind, losing momentum.
The reality is the opposite. The founders who take the time to properly realign and relaunch after PMF are the ones who cross the chasm successfully. They’re the ones who achieve the hockey stick growth curve that investors expect—not because they moved faster, but because they moved more deliberately.
The lessons learned in the first attempt at achieving product market fit (PMF), must be used to do the following:
stress test all of the original assumptions in the idea market fit (IMF) phase
use iterated IMF insights to have a second attempt and achieving the exit criteria for the 4 phases of PMF
attempt to achieve PMF through the lens of go-to-market, using the RVNU definition
if successful in #3, move to codifying sales by entering the GTM fit phase.

What This Means for Lecture 9
Stage 9: Repeatability is about proving you can achieve product-market fit with customers beyond your initial network, scaling the process to at least double the original volume.
But you can’t achieve true repeatability if you haven’t first cleaned up what you learned in the PMF phase.
You can’t repeatably acquire the right customers if you haven’t refined your ICP based on PMF data.
You can’t repeatably prove value if you haven’t documented what value looks like with your best-fit clients.
You can’t repeatably close at the right price if you haven’t eliminated the underpriced design partner deals from your mental model of “what a deal looks like.”
Next week, we’ll dive into how to build this repeatability once you’ve done the hard work of realignment. We’ll cover the transition from founder-led sales to repeatable process, the role of early sales hires, and the metrics that prove you’re ready to scale.
But first, ask yourself: have you truly completed PMF? Or are you rushing toward GTM Fit with vanity revenue that will compound into venture-killing GTM debt?
The answer is in your data. You just have to be willing to look at it honestly.
See you next week.
