Incumbents almost never lose a customer to a better pitch. They lose them to their own renewal invoices, their own unused seats, and their customers’ quiet dissatisfaction, none of which a rival can see from the outside. Displacement is an inside job, and by the time the switch is visible in a competitive deal, the incumbent already lost it months earlier.
Mystery Demo books competitors’ real sales demos as a credible buyer, incumbents included. It brings back what each rep quoted, promised and pushed: the price a new buyer gets, the multi-year terms on offer, and the answer a rep gives a buyer weighing an alternative.
We collected the most useful SaaS competitive displacement statistics we could find in public research on how often incumbents get replaced, what triggers the switch, and where the openings hide. Each figure links to the study that produced it, and if you only keep a handful, keep these:
Incumbents Lose Customers Faster Than They Think
The myth of the sticky incumbent dies when you look at the churn numbers. Software turns over constantly, and a meaningful slice of every vendor’s base is heading for the exit. Gross revenue retention, the share of last year’s revenue a vendor keeps from existing customers before any expansion, is the cleanest measure of it.
| Retention measure | Figure | Who was measured |
|---|---|---|
| Apps that leave a company’s SaaS portfolio in a year | 33%1 | Zylo, 2026 SaaS Management Index |
| Median gross revenue retention, 2025 | 84%, down from 88%6 | Aleph and Benchmarkit, 342 SaaS and AI-native companies |
| Bottom-quartile gross revenue retention, 2025 | 76%6 | the same report |
| Median net revenue retention, seat-based pricing | 98%7 | the same report |
| Net revenue retention at $25K to $50K ACV | median 102%, bottom quartile 97%8 | SaaS Capital, private SaaS companies, 2025 |
Gross churn is the number incumbents underplay, because expansion revenue papers over it: a vendor can post net retention above 100% while losing a sixth of its existing revenue. At the 2025 median of 84% gross retention, the typical company loses 16% of existing revenue a year to churn and contraction, before it adds a dollar of new business6.
Not all of it goes to a competitor, but all of it is revenue the incumbent no longer holds. The net retention rows sharpen it further: two groups sit below 100%, the median seat-based vendor and the bottom quarter of vendors at mid-market price points.
Both lose more revenue from existing customers than they win back from them, inside accounts where everything looked fine on the dashboard.
The Renewal Is Where the Switch Happens
Displacement does not happen in a flashy bake-off. It happens at renewal, and the average company runs through hundreds of them a year.
This is the central tension of displacement, and it cuts both ways. The incumbent’s defense is inertia: research before renewal dropped 17 points in a year. And only 38.1% of IT leaders treat a renewal as a chance to cut costs3, which Zylo reads as most renewals being rubber-stamped rather than scrutinized.
But the wedge is sitting right next to it, in the same survey of IT leaders:

So the grievance lands on a buyer who was not looking for it. The challenger who shows up with the price increase already documented has an opening with a customer who would otherwise have signed on autopilot.

Buyers Switch When the Incumbent Fails on Its Own Terms
The reasons a buyer replaces a vendor have little to do with the challenger’s pitch. They sit inside the incumbent’s own performance.
| Trigger | Figure | What the figure measures |
|---|---|---|
| Productivity | 26%9 | buyers naming it the top reason they replace software (G2, 2024) |
| Cost | 21%9 | buyers naming it, the third reason they replace software (G2, 2024) |
| Better AI | 49.5%10 | buyers at companies of 1,000 to 5,000 employees who switched providers in the past year for better AI (G2, 2025) |
| Regret | 59%11 | software buyers who regret a purchase from the past 18 months: a condition that opens a deal, not a switch (Gartner Digital Markets, 2025) |
The AI trigger is not even across company sizes, and the companies in the middle are moving fastest:

The switch triggers fall into two camps, and a challenger should know which one it is fishing in:
The regret figure is the quiet one to watch. When buyers regret a software purchase, the most common thing they do about it is replace it with a product from a different vendor11, so regret is an opening a challenger can work with, as long as the move feels safe.

The Waste That Sets Up the Switch
Underneath every displacement is a pile of software nobody uses and nobody is watching. It accumulates license by license, quietly, until it lands inside a renewal decision.
| Study | Share of licenses used | What was counted |
|---|---|---|
| Productiv, 2023 | 47% over a 90-day period4 | nearly 100 million SaaS licenses over three years |
| Zylo, 2026 | 54% on average3 | the 2026 SaaS Management Index |
Two measures, three years apart, land in the same place: about half of every license base sits unused, which Zylo puts at $19.8M in annual license waste for the average organization3.
An app sitting at half-used licenses, with nobody asking why, has stopped being a tool the customer relies on and become a line item waiting for a budget review. Pointing at that unused half starts the conversation the incumbent least wants: what the tool is worth.
SaaS Portfolios Are Growing Again, and Incumbents Are Buying Time
The macro force has turned. After two years of consolidation, the average stack is growing again, and BetterCloud’s 2026 report calls the consolidation era over.
Two forces now pull against each other:
What an Incumbent Tells a Buyer Who Might Switch
The hard part of displacement is that the openings are invisible from the outside: a renewal price hike, a support queue gone cold, a half-used license. A feature page will never tell you any of it, and neither can we: your prospect’s renewal is between them and their vendor.

What a buyer can see is the incumbent’s side of the same conversation: how it sells and how it holds on. We book the incumbent’s demo as a credible buyer and bring back the price it quotes, the multi-year terms it pushes, and how its rep answers a buyer weighing an alternative. In our competitor product comparison, that sits on one board beside what the product showed in the demo, with the recordings behind it.
Below is one competitor’s page from our public example board, where the client and every competitor are invented. Its Expert Analysis turns the recorded meetings into the insights a challenger would act on, each with the evidence it came from.

You have never seen the renewal conversation your prospect is having with their incumbent, and it is deciding your deal. Tell us which incumbent you keep running into, and you will know how it sells and how it holds on before your rep walks into the next deal against it.
