Post-Sale Revenue Recovery

I HELP B2B SAAS FOUNDERS STOP LOSING REVENUE THEY'VE ALREADY EARNED.

"

We only find out a customer is churning when they cancel, and by then it's already too late.

What The Data Shows
70–80%

of accounts that churn show clear signals 30+ days before they cancel

41%

average usage drop in the quarter before cancellation, visible in your data

20–40%

of churn is failed payments. Easiest to recover, almost always missed.

Most

accounts ready to expand or upgrade. No upsell conversation ever started.

The data to catch all of this is already sitting in your system.Nobody is reading it.
WHERE REVENUE LEAKS
Play 01
CHURN
They went quiet and stopped showing up.
You didn't find out until they cancelled.
Play 02
EXPANSION
The revenue is sitting inside accounts you already won.
Nobody has gone after it.
Play 03
ONBOARDING
They signed up with real intent.
Nobody caught them before they drifted away.
The Problem. In Their Own Words.
"

They churned. I felt crushed, hollowed, gutted. There was always data I had missed.

"

By the time you find out, they've already decided. The conversation you're having is a courtesy.

"

The data was always there. Nobody was reading it.

"

The quiet ones are the risk. Not the ones complaining.

How It Works

Detect. Diagnose. Prescribe.

01
Detect
Which accounts are at risk, before they tell you

Before renewal. Before the cancel email. Serona reads the behavioral signals your tools are already collecting but not interpreting, like usage drop, login gap, payment friction, feature non-adoption. The signal was always there.

02
Diagnose
What's actually happening — per account, not per cohort

Silent disengagement is different from involuntary billing failure is different from never-activated. The save play for each is completely different. Serona tells you which one you're looking at, so your team doesn't waste a call on the wrong problem.

03
Prescribe
Exactly what to do. This week. Per account.

Not a score. Not a probability. A specific action that arms your team: who to call, what to say, when. Serona is the intelligence layer. Your people are still the ones doing the work.

Who This Is For

Built For Founders Who Are Done Finding Out At Renewal.

1
Stage
₹5–100 Cr ARR. Revenue is real.
You're past early chaos, but you don't yet have a dedicated system watching accounts between renewals. Post-sale still runs on instinct, not infrastructure.
2
Setup
Good at relationships. No early warning system.
Your CS team is good at relationships, but there's no way they can proactively monitor every account for early warning signals. That's not a people problem. That's a systems gap.
3
Pain
The data is there. Nobody's reading it.
Usage logs, billing events, login timestamps, all sitting in your stack. Churn still surprises you at renewal because nobody connected the dots.
4
What you need
Not a tool. An answer.
Not a dashboard to check every morning. Someone who tells you: this account, this week, here's why, here's what to say. That's what Serona delivers.
Not for you if: You're pre-revenue, have a fully staffed CS team with existing tooling, or don't run a recurring subscription model. Serona is built for the gap between "we know churn is a problem" and "we have a system to prevent it."
Let's Start Here

No pitch. No deck. Bring a sample of your account data and I'll show you, live, which accounts are at risk, why, and exactly what to do. Actionable whether we work together or not.

That's yours whether we ever talk again or not.

The Founder

I Got Tired Of Watching Founders Find Out Too Late.

I built Serona because I kept hearing the same thing from SaaS founders:

"The signal was always there. I just missed it."

Pragya Agarwal

The problem isn't data. Every SaaS company has usage logs, login timestamps, billing events. The problem is nobody's reading them systematically, and by the time a founder notices, the customer has already decided.

Serona is the intelligence layer between your data and your CS team. I detect, diagnose, and prescribe. Your people handle the relationship. That division of labor is what works.
