Inc. magazine publishes an annual list of the fastest-growing private companies in the United States. This year’s list includes 14  language services providers (LSPs) — many of which are growing at a significantly faster rate than the average market growth rate last reported of 13.15%.

These 14 LSPs are translation and interpreting firms, all categorized under Inc’s “Business Products and Services” tab. The following table includes their Inc. 5000 rank, the company name, its three-year growth rate, and revenue for the last year.

Inc. Rank	Language Service Provider	3-Year Growth Rate	Revenue in US$ million
626	adaQuest	483%	$5.3
778	Sajan	391%	$12.7
1,707	Language Services Associates	164%	$22,0
1,808	U.S. Translation	152%	$2.6
2,127	Welocalize	122%	$50.3
2,492	TransPerfect	96%	$221.5
2,699	CETRA Language Solutions	85%	$3.0
2,720	Certified Languages International	84%	$8.3
2,936	Para-Plus Translations	73%	$2.4
3,201	Language Line Services	61%	$298.9
3,271	ProTranslating	59%	$8.9
3,719	Dynamic Language Center	42%	$6.3
4,799	Fluent Language Solutions	9%	$5.5
4,866	Eriksen Translations	7%	$5.1

The magazine’s ranking methodology focuses on rapid increases in revenue, smaller companies with strong growth over zero score higher than more established firms.

Inc’s approach differs from Common Sense Advisory’s market sizing report, which ranks LSPs not by rate of growth, but by total revenue.
