Share of listed companies that deliver each discipline in-house. Anything missing here is work you would brief to a second vendor.
Verticals the listed companies document experience in. Deep local bench means you can compare two or three shops that already know your SERP.
Connecticut listings with published headcount span 2-10 (1), 10-20 (1), 20-50 (1), 50-150 (2). Another 4 listings leave headcount Not published. Custom engagements is the most common published commercial model, which helps frame a normal engagement before a sales call.
Match scale to your problem. 2 of the 5 with published headcount are under 50 people, where the people who win the pitch usually do the work. None of the companies with published headcount operates at 150+; verify bench depth directly for multi-market programmes.
Treat the retainer floor as a scope signal. A $1k/mo floor and a $1.9k/mo floor rarely describe the same deliverable set. Ask each shortlisted company to map its floor to hours, content output and technical work per month, then compare those, not the price.
Verify tenure independently. Among the 4 listings with a sourced founding year, median tenure is 0 years; the longest-running listing, RJ Media Group, has traded since 1867. Founding dates can be checked against company registers and archived versions of the site.
