Decision Framework by ARR Stage

The right model depends on your analytical maturity, not just your headcount.

Pre-revenue → $1M
Scoped agency engagement
Set up instrumentation correctly. Define your activation event. Cover the 3–4 metrics that matter now. You do not need a full analytics function — you need clean infrastructure.
Agency: instrumentation setup + funnel definition
$1M → $5M
Agency retainer
Enough users to see meaningful signals, but no dedicated analytics function. An agency covers ongoing analysis, funnel diagnostics, and PMF interpretation faster than you can hire and ramp.
Agency: $5K–$15K/mo retainer beats premature hire
$5M → $20M
Hybrid: internal owner + agency strategy
One internal data engineer owns the technical layer and daily questions. An agency runs strategic analysis and deep-dive work. Often less than two in-house hires and more productive.
Hybrid: optimal structure in this range
$20M+
Internal team primary, agency specialist
Analytics is now a daily operational function. Internal people are essential. Agencies shift to specialist projects: tool migrations, growth audits, and external challenge of entrenched assumptions.
In-house primary — agency for strategic review cycles
