# Annual Recurring Revenue (ARR)

**Prerequisite knowledge:** **Annual Recurring Revenue (ARR)** — the normalized annual value of recurring (subscription) revenue.

The underlying study focuses on companies generating between **$500,000 and $10 million in ARR**. Understanding SaaS revenue mechanics is necessary to place the analyzed startups at the correct maturity stage — **post-seed, early growth** — rather than pre-revenue or late-stage.

**Why it matters here:** The hiring-timing guidance in [[claim-early-sales-hires]] is ARR-indexed (e.g., benchmark playbooks tie the first sales hire to $1M+ ARR with a documented playbook and ≥20% close rate).
