Orbit Media: average website lifespan across Inc 5000 is 2y4mo; under continuous care, 6y4mo

Claim: Orbit Media reports the average website lifespan across the top of the Inc 5000 list is "just 2 years and 4 months." Their own client base — sites under continuous care — averages "6 years and 4 months" between major redesigns. Lifespan is a function of architecture and maintenance, not a fixed property of websites.

Confidence: Industry-consensus (Orbit's own benchmark + Databox survey of 145 SMBs they cite).

Honest caveat: The frequently-recycled "2 years 7 months" lifespan figure (attributed to HubSpot in many agency blogs) could not be verified at primary source. Use Orbit's 2y4mo Inc-5000 number, not the unverifiable HubSpot one.
