Reading Through the Platform Pitch

The end of the growth-at-all-costs era

For nearly a decade, SaaS investors rewarded a single metric above all others: revenue growth rate. Companies raised at astronomical multiples by proving they could double ARR year-over-year, often at the expense of unit economics that made little sense.

That era ended in 2022. Rising interest rates, tightening public markets, and a series of high-profile write-downs forced a reckoning across the industry. What replaced the obsession with growth was a more nuanced framework — one that balanced expansion with efficiency.

The five metrics that matter

After working with dozens of mid-market SaaS companies preparing for fundraising or exit, our framework consistently returns to five core indicators.

1. Net Revenue Retention

NRR measures the revenue retained from existing customers over a period, including expansions, contractions, and churn. A business with NRR above 120% is growing even without acquiring new customers — which fundamentally changes the economics of customer acquisition.

Best-in-class SaaS businesses maintain NRR between 115-130%. Anything below 100% indicates the business is losing money from its existing base, making growth purely dependent on new sales velocity.

2. CAC Payback Period

How long does it take to recover the cost of acquiring a customer? In 2021, payback periods of 24-36 months were acceptable given the capital environment. In 2026, investors increasingly expect payback under 18 months, with elite companies achieving 12 months or less.

ARR composition matters as much as total ARR

One lesson from working with companies preparing for M&A is that buyers scrutinise ARR quality, not just size. Three common issues that destroy valuation multiples:

• Multi-year contracts booked as ARR in year one, masking churn
• Services revenue bundled into SaaS contracts without separation
• Renewal timing manipulation to inflate period-end metrics

Clean ARR reporting, with consistent definitions applied across sales, finance, and customer success, is a prerequisite for any exit process. It's also increasingly a requirement for Series B and beyond fundraising rounds.

Building the right data infrastructure

These metrics are only as reliable as the systems that generate them. The companies that track KPIs most accurately have typically made three foundational investments: a single CRM as the source of truth for customer data, a BI layer that reconciles CRM and finance systems, and standardised definitions documented and enforced across teams.

Without this infrastructure, even sophisticated finance teams find themselves producing conflicting numbers from different sources — precisely the scenario that undermines investor confidence at critical moments.
