How is revenue split between enterprise, mid-market, and SMB, and how is the mix evolving?

№ 007 · Revenue mix by segment

01

Definition

MetricShare of ARR by customer segment (enterprise, mid-market, SMB) and its drift

Unit% of total ARR per segment

Stacked area of Enterprise, Mid-market, and SMB ARR with absolute dollars and percent annotations inside each band. Tag every customer with a segment in CRM, sum ARR per segment quarterly. Watch SMB shrinking while Enterprise grows for healthy upmarket move. Example: Q1 Enterprise $2.4M (38%), Mid $2.4M, SMB $1.5M.

SMB
Small and medium business. Segment label, usually under 200 employees or a defined contract-value band.
ARR
Annual recurring revenue. MRR at period end multiplied by 12, or the annualised value of active contracts.
CRM
Customer relationship management system. The system of record for accounts, contacts and pipeline.

Benchmarks

Bottom 30%MedianTop 30%
Accidental mix: three segments each 25-40% with three different sales motions and no segment above the company's blended NRRMixed books at $5-50M ARR commonly carry 2 segments of 30%+ each, with mix drifting toward higher ACV over time as ACVs roughly double between the $5-10M and $10-20M ARR stagesDeliberate mix: one anchor segment above 50% of ARR with the fastest-retaining segment gaining share year over year

Private B2B SaaS; no survey publishes revenue-mix quartiles, so bands here are structural readings anchored to segment ACV and retention data (segment ACV anchors: SMB roughly $5-15k, mid-market ~$40k, enterprise ~$220k for public comparables) · This chart has no published distribution; the value is in the drift, not the level. Confidence is low by construction and stated as such. The retention economics that make mix drift matter are well evidenced: NRR runs ~97% SMB vs ~118% enterprise, so mix shift mechanically moves blended NRR.

Category split omitted: Revenue-mix distributions by segment are not published by any Tier 1-2 source; only per-segment ACV and retention anchors exist.

When it looks bad

The lowest-retaining segment's band widens over consecutive periods, meaning the company is acquiring fastest exactly where revenue quality is worst.

SMB grows from 30% to 45% of ARR in a year while SMB NRR sits at 95% vs 112% for mid-market; blended NRR falls 4 points with no change in execution, purely from mix.

What to do about it

  • Price the mix decision explicitly: model blended NRR under the current acquisition mix vs a mid-market-weighted mix; with a ~21-point NRR spread between SMB and enterprise, a 10-point mix shift can move blended NRR 2 points, worth ~1 point of annual growth (SaaS Capital NRR-growth relationship).
  • Serve the low-ACV segment with a different cost structure, not less attention: self-serve onboarding, community support and annual-first billing; do not staff SMB with the mid-market CS model or the segment turns gross-margin negative.
  • Before adding a third segment, check the ChartMogul finding that companies focused on $300-2,999/month customers grow fastest; a third motion usually costs more in focus than it returns in TAM.
  • Set a mix guardrail in the annual plan (for example no segment below the company's blended GRR may exceed 35% of new bookings) so the drift is a choice, not an accident.
