Slator released the Slator 2025 Language Service Provider Index (LSPI) at the end of February 2025, the eighth annual iteration of our flagship index. Currently featured in the Slator 2025 LSPI are more than 290 language service providers (LSPs) ranked by 2024 (USD) revenue.
The combined revenues of Slator 2025 LSPI companies grew 6.6% in 2024 to USD 8.4bn. While promising at first glance, a significant portion of this growth is thanks to M&A-driven consolidation, and organic growth (excl. acquisitive growth) across LSPI companies is estimated to be flat.
Drilling down further reveals a mixed environment for LSPs in 2024. Excluding the LSPs that are “Pending,” i.e., for which no growth data is yet available:
- 54% of LSPs reported positive growth;
- 40% reported declining revenues; and
- 6% remained flat, managing to match 2023 revenues.
Below, we take a closer look at the top 10 fastest-growing LSPs in the 2025 LSPI — half of which happen to be based in the US.
Propio Language Services
Super Agency Propio Language Services, ranked #5 on the 2025 LSPI, reported a growth rate of 164.7%, thanks in part to a number of acquisitions in late 2024. As Slator reported, Propio acquired United Language Group in a September 2024 deal, followed by two more acquisitions before the end of 2024: Akorbi, one of the largest privately owned LSPs in the US, and ASL Services Inc., a specialist in services for Deaf and Hard of Hearing communities. Post-acquisitions, Propio grew to more than 1,000 employees across several companies.

Maya Bridge Language Services
Doubling annual revenues may be easier for Boutiques than for larger companies, but Maya Bridge Language Services (#169 on the 2025 LSPI) did it while specializing in languages of lesser diffusion in the US; namely, 22 languages indigenous to Central and South America, spoken by about six million people. A surge in migration from those regions to the United States, and the resulting large demand for Mayan language interpreting in the public sector, helped propel Salt Lake City, UT-based Maya Bridge Language Services’ growth from USD 1m in 2023 to USD 2m in 2024.
Language Network
This is not Language Network’s first time in the fast lane: The Riverside, California-headquartered Challenger was named one of Inc.’s 5000 Fastest Growing Companies in 2022. The family-founded LSP has grown to cover 200 languages with more than 4,000 language professionals, with regulation and compliance driving double-digit growth in US interpreting in 2024. Language Network, #59 on the 2025 LSPI, similarly enjoyed a growth rate of 80.9%, bringing revenues of USD 9.4m in 2023 to USD 17m in 2024.
Accent on Languages
The second Californian company on this list, Boutique Accent on Languages (#106 on the 2025 LSPI) was founded over 30 years ago and is now headed by a graduate of Middlebury Institute of International Studies’ prestigious conference interpreting program. Accent on Languages grew 66.7% from USD 3m in 2023 to revenues of USD 5m in 2024.
Dals
Rounding out the top five, the UK business formerly known as DA Languages is classified as a Leader, ranking #19 on the 2025 LSPI. Dals grew revenues by 59.5%, from USD 47.1m in 2023 to USD 73.9m in 2024. A June 2024 merger, which saw Dals’ parent company Valorem Group acquire Irish interpreting software firm TRANSLIT, may have provided a boost.
White Globe Group
Indian Boutique White Globe Group holds five ISO certifications, and, in addition to Indian government clients, serves customers in 50 countries, including Netflix and multiple Fortune 500 companies. Founded in 2016, the LSP (#92 on the 2025 LSPI) reported a 52.8% increase in revenues, from USD 4.3m in 2023 to USD 6.4m in 2024.
Clearly Local
This Hong Kong-headquartered Boutique, founded in 2016, currently has openings for copywriters and translators in China; business development specialists in several European countries; and a lead generation specialist in the Philippines. In other words, business seems to be booming — and the numbers back it up: Clearly Local, #120 on the 2025 LSPI, reported revenue growth of 52%, from USD 2.5m in 2023 to USD 3.8m in 2024.

Translayte
Score another one for the Brits — though this UK Boutique has workers in 14 countries and clients in 100. Translayte grew 47.7% in 2024, from USD 3.8m to USD 5.5m, and earned spot #103 on the 2025 LSPI.
Logrus Global
Wrapping up the Top 10, Pennsylvania-based Logrus Global (#109 on the 2025 LSPI) was founded in 1993 and focuses on language services for the fields of technology and engineering; the LSP also contributed to a 2023 study on the use of smaller language models for clinical translations.
