Security Alarm Company
The only business valued at 40x a single month's revenue
Security alarm companies install and monitor burglar alarms, fire alarms, and cameras for homes and businesses. The monitoring contract — typically $20–$60/month per account — is the real asset. These accounts renew automatically, churn less than 5% per year, and trade at 35–45x monthly recurring revenue (MRR) — a valuation model unlike any other industry. A company with 300 monitored accounts at $35/month is worth $370K–$470K, even if it's a one-person operation.

How It Works
The company installs alarm systems at residential or commercial properties, often at low or no upfront cost, then charges a monthly monitoring fee. Monitoring is outsourced to a central station ($3–$8/account/month), so the owner pockets the spread. Revenue scales with account count. Acquisitions are typically priced at 35–45x MRR, meaning 1,000 accounts at $35/month = $35,000 MRR = worth $1.2M–$1.6M to a buyer.
