Best QA companies in the USA, 2026

The companies

How this ranking was put together

Membership is computed from the profile, not chosen: companies appear here when they have a delivery location in one of the countries the USA covers, as their own profile states. Position in a ranking cannot be bought. Paid options are limited to the extended profile, labelled sponsor slots and lead forms, and none of them affect tags or order.

The table compares the fields that decide this axis: delivery locations, published rates, team size, plus the number of verified reviews on external platforms. Rates, minimum project size and onboarding time carry the source they came from next to the value.

• Automation first: Test automation is offered as a service, and at least one published case study reports a coverage or regression time metric.
• Nearshore for the EU: At least one delivery location in the EU or the EEA, or in Ukraine, Georgia, Serbia or Moldova.
• Nearshore for the USA: At least one delivery location in Canada, Mexico, Central America or South America.
• Embedded team model: The dedicated team engagement model is offered, and at least one published case study.
• Performance engineering: Performance testing is offered as a service, and at least one published case study reports a throughput or latency metric.
• Security focus: Security testing is offered, together with either penetration testing or a verified ISO/IEC 27001 certificate, and at least one published case study.
• Device lab coverage: A published device lab of 100 real devices or more, with a source.
• Crowdtesting at scale: The crowdtesting engagement model is offered, and a published tester pool of 10,000 people or more, with a source.
• Enterprises: A verified ISO/IEC 27001 or SOC 2 certificate, a published team size of 201-500 or larger, and at least one named client that is a publicly traded company, each with a source. A company that publishes no team size does not carry this tag.

The criteria for this axis are on the methodology page, together with field definitions and the rule for editorial order. Changes of order are recorded in the changelog.

Questions

US delivery is the expensive option on most shortlists. Where does the entry ticket actually start?

At 1,000 US dollars, and it climbs steeply from there. Seven companies publish that floor, and eleven publish 5,000 dollars, the most common figure here. Seven more publish 10,000 dollars, level with the 1,000 dollar floor, and one publishes 5,995 dollars, just above that pair. Above them, two publish 25,000 dollars, two publish 50,000 dollars, one publishes 75,000 dollars, one publishes 100,000 dollars and one publishes 250,000 dollars, which is 250 times the lowest floor recorded. Twenty-one companies publish no floor at all. The field holds the smallest engagement a company says it will accept, so it marks a threshold rather than a price.

We are a scaleup, past the startup stage and short of an enterprise. Does anything point at companies used to that size?

One profile names that stage directly. Nine companies name startups and enterprises together. Ten name enterprises alone. One names startups alone, and one names startups together with agencies rather than enterprises. Thirty-two name no client stage at all. The single profile that names a scaleup names all three stages at once, so it does not single the middle out either. A buyer in the middle is choosing among profiles that describe the two ends of the range and one that describes the whole of it.

Whose names can we actually open and check before we shortlist?

Each name comes with the source it was read from, a case study, a testimonial or a published client list, so every one of them can be opened. Thirty-nine profiles carry at least one name. Three of those carry 15, 13 and 12 names, and no other profile reaches ten; below the top three the counts run from one to nine. Fifteen profiles carry no name at all. The field holds the name and its citation, without the year of the work or how much of it there was.

How to choose a vendor on this axis

Published by QA RatingPublished on September 3, 2026Updated on September 3, 2026

Every fact about a company comes from a listed source. A field without a source stays empty. A certificate counts as confirmed only when a registry, certificate or auditor report backs it; a certificate the company only claims about itself is published separately, under that label. Vendors can request a correction at hello@qa-rating.com. A correction is applied when it comes with a public source.
