How is a Churn Health Grade calculated?

Every teardown starts at 100 points. Each churn driver identified by the AI subtracts by severity: critical -20, high -12, medium -6, low -2. The score floors at 0. Letter bands: A is 80 and up, B is 65 and up, C is 50 and up, D is 35 and up, F is below 35. Same scoring runs on your own cancellation feedback.

Which SaaS has the worst churn grade in this teardown roundup?

Evernote and the Asana and Notion combined teardown both hit grade F. Evernote's F is driven by Bending Spoons-era price hikes compounding with feature removals and sync regressions. The Asana and Notion combined F reflects billing trust collapse across both platforms in 15 Trustpilot reviews.

Which SaaS has the best churn grade in this roundup?

Linear at grade B. Linear's churn pattern is narrow and bounded: teams outgrow the opinionated workflow rather than cancel over trust, billing, or pricing. A B grade is what healthy churn looks like when pricing is not in the critical path.

What is the most common churn driver across SaaS teardowns?

Pricing is the accelerant. Eight of the eleven teardowns have a pricing decision at or near the critical driver. Cursor's June 2025 restructure, Figma's +33% hike, Slack's Hack Club bill, HubSpot's 5x tier migration, Asana's SSO tax, Monday's cancellation banner, and Evernote's Bending Spoons increases all show the same mechanic: pricing change amplifies existing trust issues.

Can I teardown my own SaaS using the same methodology?

Yes. Paste your cancellation feedback (or public complaints if you do not have internal data yet) at retentioncheck.com/try. The same scoring, severity, confidence, and quote-attribution pipeline used in these teardowns runs on your data. No signup required for the first analysis.

The Best SaaS Product Teardowns of 2026: 11 Case Studies Graded A to F

Most product teardowns read like design critiques dressed up as strategy. Pretty screenshots, vague takeaways, no math. The ones below are different. Every one of these companies has a public trail of cancellation feedback on Hacker News, Reddit, G2, Trustpilot, and their own customer forums. I ran that feedback through RetentionCheck and got a Churn Health Score (A to F) backed by severity, confidence, and the exact customer quotes that moved the grade.

This post is the index. Eleven teardowns live, graded, ordered from worst to best. The one pattern that shows up across all of them is at the bottom.

How the Churn Health Grade works

Every teardown starts at 100 points. Each churn driver surfaced by the AI subtracts points by severity: critical is -20, high is -12, medium is -6, low is -2. Letter grade bands: A is 80+, B is 65+, C is 50+, D is 35+, F is below 35. Same scoring runs on your own cancellation feedback at retentioncheck.com/try.

The 11 teardowns, ranked

1. Evernote · Grade F

Under Bending Spoons ownership, Evernote's cancellation feedback reads like a break-up letter. Price hikes compounded with feature removals, sync reliability regressions, and a community that watched Obsidian and Notion absorb their use case. First F-grade teardown I ran. Read the Evernote teardown.

2. Asana + Notion combined · Grade F

15 Trustpilot reviews. Billing trust collapsed on both platforms for overlapping reasons: auto-renewal opacity, support loops, and the feeling that neither company cared about the individual customer once they had the card on file. Two unicorns, same disease. Read the Asana and Notion combined teardown.

3. Cursor · Grade D

The June 2025 pricing restructure is the defining trust event. Pro pricing flipped from 500 fast responses per month to "$20 of API usage," which halved effective capacity for heavy users. CEO apologized, refunds were issued, migration to Claude Code and Windsurf accelerated. Score: 42 out of 100. Read the Cursor teardown.

4. Figma · Grade D

The March 2025 pricing hike (+33% on Professional) broke the implicit contract with smaller teams. Penpot's Hacker News thread hit 632 points the week of the change. Not a product problem. A pricing trust problem. Read the Figma teardown.

5. Slack · Grade D

The September 2025 Hack Club pricing incident (a 40x bill shock) compounded with the forced Business+ migration and the broader sense that Salesforce ownership was dismantling Slack's trust with the long-tail of teams. The churn pattern is more about governance than features. Read the Slack teardown.

6. HubSpot · Grade D

A 5x price hike on the tier existing customers were on, paired with a forced migration path that looked like a revenue play more than a product improvement. The backlash wrote itself on Reddit and G2 throughout late 2025. Read the HubSpot teardown.

7. Notion · Grade D

60+ Hacker News and Reddit complaints. Feature bloat, mobile performance regression, AI features users did not ask for getting pushed into the core editor. The mid-life SaaS crisis story. Read the Notion teardown.

8. Monday.com · Grade C

The daily cancellation banner is real. Users report seeing a "cancel your subscription" option nudged into the dashboard UI in ways that feel adversarial. Combined with pricing increases, the mid-score reflects real pain but not full trust collapse. Read the Monday.com teardown.

9. Asana · Grade C

The SSO tax is still working. Asana gates SAML behind the most expensive tier and keeps Google SSO free, which is textbook "identity tax" packaging. Post-IPO monetization discipline is visible in the churn feedback. Read the Asana teardown.

10. Zoom · Grade C

Security trust cracks (the 2020 incidents still surface in cancellation reasoning) combined with real competitive pressure from Google Meet, Microsoft Teams, and emerging tools. Not a collapse. A slow bleed. Read the Zoom teardown.

11. Linear · Grade B

The outlier. Linear's churn pattern is narrow and bounded: teams that outgrow the opinionated workflow rather than trust collapse, billing surprises, or pricing shocks. The B grade is what healthy churn looks like when the product is doing most things right. Read the Linear teardown.

The one pattern across all 11 teardowns

Pricing is the accelerant. Eight of eleven teardowns have a pricing decision at or near the critical driver. Cursor's restructure, Figma's 33% hike, Slack's Hack Club bill, HubSpot's 5x migration, Asana's SSO tax, Monday's cancellation banner, and Evernote's Bending-Spoons-era increases all show the same mechanic.

The product gets blamed. The pricing change is what moved the cancellations.

Linear's B grade is instructive for the opposite reason: pricing is out of the critical path. The churn that exists is about fit, not trust.

What to do with this if you run a SaaS

Three uses.

1. Benchmark against your own. Pull 40-60 public or internal cancellation reasons. Run them through retentioncheck.com/try. Your grade slots into this list. If you are sub-C, the drivers are usually identifiable in an hour.

2. Read the teardowns for the category you compete in. If you are in AI dev tooling, Cursor is the cautionary tale. Design tooling, read Figma. Project management, read Asana, Monday, and Linear together. The patterns generalize.

3. Use the grade bands to pressure-test a pricing change. If your current grade is C or lower, a pricing change right now compounds existing trust damage. If your grade is B or A, you have room. The Cursor teardown specifically shows what happens when you change pricing while unresolved trust issues are still visible.
