Improving burn multiple means either generating more ARR per dollar of spend, or spending less to generate the same ARR.
Why burn multiple deteriorates
The most common causes of burn multiple creeping up:
1. Expansion ARR isn't scaling: New ARR relies entirely on expensive acquisition. If NRR is below 100%, net new ARR is capped by acquisition, and every new customer costs full CAC.
2. CAC is rising: Paid channels saturate. Cost per lead increases. Conversion rates drop. Same spend, less ARR.
3. Churn is absorbing expansion: High churned ARR offsets new ARR. The denominator (net new ARR) shrinks even if gross new ARR grows.
4. Fixed costs grew ahead of revenue: Hiring in anticipation of growth that didn't materialize. Burn grows; ARR growth doesn't.
Lever 1: Drive expansion ARR
Expansion ARR requires near-zero additional burn. If a customer expands from $1k to $2k MRR, you generate $12k additional ARR without additional S&M spend.
At 30% expansion ARR as a share of net new ARR, burn multiple improves by roughly 30% with no other changes.
Lever 2: Reduce CAC through channel optimization
Stop spending on channels with burn multiple > 3× at the channel level. Identify which channels (paid search, outbound, content, referral) have the best ARR-per-dollar and reallocate.
Lever 3: Improve churn to lift net new ARR denominator
Every churned dollar reduces net new ARR directly. A company adding $500k gross new ARR but churning $200k has $300k net new ARR. Fix the $200k churn and burn multiple improves by 67% without touching acquisition spend.
Lever 4: Cut inefficient non-S&M spend
Burn multiple suffers when operational overhead grows disproportionately. Audit non-growth spending: infrastructure, G&A, tools, underperforming hires. Even $50k/month in reduced operational burn improves net burn by $600k/year.
