How is this ranking worked out?

The order comes from what each firm publishes and what has been verified about it, and never from payment:

Profile completeness: the details a buyer needs to judge a firm — what it does, who it serves, how it prices, who it has worked for
Earned trust: verification, awards and the other checks a firm has actually passed
Client reviews, where they exist: the rating is smoothed, so one five-star review cannot outrank a firm with a hundred good ones, and volume counts with diminishing returns

Client reviews are still rare across this catalogue, so on most lists today the order is set by the first two. A firm near the top is the best-documented and best-verified one we hold, which is not the same claim as the best one to hire. Use the list to build a shortlist, then check the firms yourself.

Sponsored listings are labelled and shown apart from this list. How rankings work

Only firms whose profile names the USA are counted here, so a firm that lists a town but no country is not yet included.

Where else can I look?

The same list elsewhere: UK (240) · India (62) · Germany (59).

Other specialisms in the USA: e-commerce (1,539) · Android app development (1,530) · iOS app development (1,452) · UI/UX design (1,355) · PHP development (946).
