Know which customers will churn before they do.
Fernly watches product usage, support tickets and billing signals, then tells your team which accounts need attention this week — while there is still time to save them.

1,847 founders and CS leads are already in line. From seed-stage startups to forty-person customer teams.
From scattered signals to a Monday morning list
Three steps. The third one is the product.
Connect
Plug in Stripe, your product database and your help desk with read-only keys. Twenty minutes, no engineers on standby.
Score
Every account gets a live health score built from usage depth, support sentiment and billing signals — with the “why” attached.
Act
Your Monday digest lists the accounts that need attention this week, ranked by revenue at risk, each with a suggested play.
Everything you need to run retention like a system
Not another dashboard to check — Fernly comes to you with the short list.
Scores that explain themselves
Every health score unpacks into the exact signals that moved it — no black box, no “trust the algorithm”.
Renewal radar
A rolling 90-day view of every renewal, ranked by revenue at risk, so nobody finds out at the renewal call.
Slack & email digests
The Monday digest lands where your team already lives. Urgent drops trigger same-day alerts.
Playbooks, not guesswork
Each risk type maps to a play — check-in call, training session, exec escalation — with templates included.
Segments that stay fresh
Slice by plan, industry, owner or lifecycle stage. Segments update live as accounts move.
Read-only by design
Fernly never writes to your systems. Read-only keys, SOC 2 hosting, data deleted on cancellation.
Teams that stopped being surprised
“We saved two of our five biggest accounts last quarter because Fernly flagged them six weeks before renewal. It paid for the year in one save.”
Head of Customer Success, Copperwick
“The Monday digest replaced a 45-minute pipeline meeting. The team just works the list now — the arguing about who’s at risk is gone.”
Co-founder, Fieldnote
“Setup genuinely took an afternoon. Read-only keys meant security signed off the same day — that never happens.”
VP Operations, Tidewater

Pricing goes live on launch day

Fair questions, straight answers
From three signal groups: product usage (logins, feature depth, seat activity), support health (ticket volume and sentiment) and billing signals (failed payments, downgrades, invoice disputes). Each score expands to show exactly which signals moved it, and Growth plans can re-weight the groups to match how churn actually happens in your business.
Stripe and Paddle for billing; Intercom, Help Scout and Zendesk for support; Postgres, MySQL and Segment for product usage; Slack for alerts. Connections use read-only credentials and take about twenty minutes end to end.
Fernly is read-only by design — it never writes to your systems. Data is encrypted in transit and at rest, hosted on SOC 2 Type II infrastructure, and deleted within 30 days of cancellation. A DPA is available on every paid plan.
The Starter plan exists exactly for this. If you have more than twenty paying customers, you already have accounts quietly going cold — Fernly is the difference between noticing in week two and noticing at the cancellation email.
You pick a plan or you walk away — we don't take a card up front, so there's nothing to forget to cancel. Your connections and score history are kept for 30 days in case you come back.
Early 2027, onboarding the list in order. Waitlist members get first access, founding-member pricing (30% off for life) and a hand from us with the initial setup. We send one email at launch — no drip sequence, promise.
Yes — the Scale plan supports multiple isolated workspaces under one login, one invoice. About a fifth of our customers are agencies and fractional CS operators running retention for client portfolios.
