Raising a Series A should feel like momentum.

More customers. More people. More confidence.
Yet for many SaaS founders, this is the stage where churn quietly starts to rise - often for the first time.

Not dramatically.
Not all at once.
But enough to create unease.

And the most frustrating part? Everything appears to be going well.

Why churn doesn’t show up immediately

In the early days, churn is easy to rationalise.

Customers leave because:

• The product is still evolving

• The ICP isn’t fully defined

• Founders are personally managing key accounts

At this stage, churn feels understandable.

After Series A, expectations change.

You’ve found product–market fit, built a small Customer Success or support team, and started selling larger contracts. Investors expect predictability but retention often hasn’t been designed deliberately yet.

The most common reasons churn rises post-Series A

1. Customer Success becomes reactive, not intentional

As customer numbers increase, Customer Success often shifts from relationship-led to activity-led.

Teams focus on:

• Support Tickets

• Meetings

• Check-ins

But lose sight of:

• Customer outcomes

• Commercial risk

• Renewal signals

Without structure, problems aren’t spotted early BUT they surface at renewal.

2. Founders step back before the system is ready

This transition is hard.

Founders quite rightly want to step out of day-to-day customer conversations, but often do so before Customer Success has clear ownership or structure.

What gets lost:

• Context

• Judgement

• Priority decisions

What replaces it:

• Activity without clarity

3. Renewals become real but ownership is unclear

Pre-Series A, renewals are informal.

Post-Series A:

• Contracts are larger

• Stakeholders are more senior

• Expectations are higher

Yet many teams haven’t clearly defined:

• Who owns renewals?

• What “healthy” actually means

• When intervention should happen

Churn increases not because teams don’t care but because no one owns the full customer lifecycle.

4. Metrics exist, but insight doesn’t

Most SaaS businesses track:

• Usage

• CSAT or NPS

• Support volume

But few connect these signals to:

• Renewal risk

• Expansion opportunity

• Commercial impact

• 
  

What successful SaaS teams do differently

Teams that stabilise churn after Series A tend to focus on 3 things.

1. Clear Customer Success ownership

Not just roles but decision-making authority.

Someone must own:

• Risk prioritisation

• Renewal strategy

• Trade-offs between customers

2. A structured retention and renewal motion

Successful teams don’t wait for churn signals.

They:

• Identify risk early

• Align Customer Success, product, and leadership

• Treat renewals as a process, not an event

3. Experience before scale

Instead of rushing to hire, they bring in experienced Customer Success leadership to design the function properly before scaling it.

This avoids:

• Rework

• Conflicting processes

• Costly senior hires too early

Elevate CS thoughts…

Churn increasing after Series A isn’t a failure but a signal and an opportunity to get ahead.

It is a signal that the business has outgrown its early-stage Customer Success approach, and that retention now needs structure, clarity, and leadership.

Handled well, this stage becomes a turning point - where Customer Success shifts from firefighting to a genuine growth lever.

If churn or renewals feel harder to manage as your business scales, it’s often a sign that Customer Success needs clearer ownership and structure and not just more activity and general noise. This is where a Customer Success professional will help.
