Customer Success Platform

Churn begins
in the penumbra.

Risk rarely announces itself. It gathers quietly in the gray zone — a slipping login, a quiet champion, a renewal no one is steering. Penumbrai brings those faint signals into focus and gives your team the workflows to act before the account goes dark.

pe·num·bra /pəˈnəmbrə/

The region of partial shadow surrounding a total eclipse — the place where things are neither in full light nor fully lost. It is where you still have time to act.

Built for revenue-minded customer success teams

The problem

Most platforms tell you an account is on fire.
Few help you notice the smoke.

01

Signals arrive too late

Health scores flip red the quarter before renewal — long after the moment you could have changed the outcome.

02

Your data doesn't fit the box

Every business measures success differently. Rigid schemas force you to bend your reality to fit the tool.

03

Insight without execution

Dashboards point at risk, then leave the work to an already-stretched CSM. Nothing actually happens.

The platform

Sense the signal. Score the risk. Do the work.

One connected surface for the entire post-sale lifecycle — from the first faint warning to a closed renewal.

Signals

Catch risk while it's still faint

Penumbrai continuously reads the shadow — product usage, support sentiment, invoice health, stakeholder movement — and raises signals the moment a pattern bends the wrong way, not a quarter later.

  • Composable health scores you can actually explain
  • Leading indicators, weighted to your business
  • Every signal traces back to the underlying evidence

Playbooks

Turn a signal into a sequence of actions

When a signal fires, the right playbook runs itself: assign the owner, draft the outreach, schedule the check-in, open the risk review. Your team spends time on judgment, not busywork.

  • Trigger on any signal, field, or lifecycle change
  • Branching steps with owners, due dates, and escalation
  • A library of proven plays, or build your own in minutes

Renewals & Expansion

Forecast the number you'll actually hit

Every renewal and expansion play in one pipeline, weighted by real health — not gut feel. See the quarter's exposure, the upside, and exactly which accounts move the number.

  • Bottoms-up NRR and gross-retention forecasting
  • At-risk ARR, ranked by recoverability
  • Expansion signals surfaced next to the risk

Flexible data

Model your customers the way they actually are

Penumbrai has no opinion about your schema. Define the objects, fields, and relationships that matter to your business — then health scores, segments, and playbooks all build on top of them.

  • Custom objects & fields. Subscriptions, deployments, devices, patients, portfolios — whatever your world contains.
  • Warehouse-native. Sync from Snowflake, BigQuery, or your product's API without flattening it first.
  • Everything is composable. Any field you define can drive a score, a segment, or a play — no engineering ticket required.

Data & integrations

Every signal your customers give you — in one model

Most platforms handle the tidy, structured half of your data. The truth about an account lives just as much in the messy half: the tickets, the calls, the emails. Penumbrai treats both as first-class.

Structured

Metrics, warehouse & CRM

Usage, ARR, seats, renewal dates, subscriptions, deployments — synced from your warehouse and CRM, or modeled as custom objects with no migration.

SnowflakeBigQuerySalesforceStripeSegmentCustom objects
table → object → health factor
Unstructured

Tickets, calls, email & notes

Support conversations, call transcripts, emails, QBR notes and NPS verbatims are enriched with sentiment, themes and a summary — then mapped to the right account.

Where Penumbrai stands

The leaders are capable and proven. They are also, in different ways, heavy, narrow, or slow to stand up. An honest read of the trade-offs:

  • Live in two weeks, configured by the team that uses it
  • A data model shaped to your business
  • Signals that trigger the work automatically
  • Pricing that scales with you, from Series A up
