CSA Research publishes an annual ranking of the largest language service providers, and it turns up constantly in procurement documents. This sets out what the ranking is based on, what a continuous listing means, and the three questions it does not answer for you.
- It ranks revenue, not translation quality
- Listed once and listed continuously are different claims
- Three questions it does not answer
It ranks revenue, not translation quality
CSA Research (formerly Common Sense Advisory) is an independent analyst firm covering the language services industry. Its annual ranking of language service providers is built on verified annual language services revenue — the firm collects financial data from providers, cross-checks it, and orders the list by size.
That determines what the ranking can and cannot tell you. Appearing on it means a provider has real, verifiable global volume rather than a website and a handful of freelancers. It does not measure output quality, and it does not measure capability in any particular field — a games localisation company and a pharmaceutical submissions company can sit next to each other on the list.
So in a procurement context it answers "is this company real, and is its scale a fit for my volume". It does not answer "can this company handle my kind of document".
Listed once and listed continuously are different claims
The ranking is rebuilt every year. A single appearance means revenue cleared the threshold that year. Sustained presence across many years means the volume held through several cycles — including the spread of machine translation, the shift in demand through the pandemic years, and the pricing pressure generative AI has brought over the last two.
Angel Translation has been listed continuously since 2015. The ranking is published annually by CSA and is not paid for by the providers on it.
That is a different kind of evidence from credit-rating certificates, which commercial rating firms issue on the basis of a company self-assessment and which state on their face that they attest only to credit status. We display the two separately rather than as one list.
Three questions it does not answer
Whether anyone there has actually handled your document type. Ranking has nothing to do with domain capability. Semiconductor datasheets, device instructions for use and aircraft maintenance manuals each carry their own conventions and terminology systems. What matters is demonstrated experience with that specific material, not total revenue.
Whether an independent revision step exists. This is mandatory under ISO 17100 and not required by ISO 9001 — the translator may not review their own work. Revenue scale says nothing about it.
Who carries the cost when something goes wrong. The ranking says nothing about liability. What decides that is how the contract handles rework, late delivery and confidentiality obligations.
Getting answers to those three does more for the outcome of a project than verifying a ranking.
