The Slator Index benchmarks leading Language Solutions Integrators (LSIs) and Language Technology Platforms (LTPs), offering a global view of how the language industry delivers multilingual capabilities at scale.
The 2026 edition covers more than 300 companies and highlights key market shifts and growth dynamics across language AI, technology platforms, and integrated solutions.
The Index captures revenue and growth data for LSIs, alongside a set of directional metrics for LTPs to track traction, positioning, and market evolution, complemented by core company data such as buyer and solution focus.
Key Insights
The 2026 Slator Index shows top-line growth, but this should not be interpreted as evidence of underlying market expansion.
As participation in the Index is voluntary, results are skewed toward higher-performing firms. At the same time, M&A activity continues to inflate aggregate revenues, concentrating growth among acquisitive players rather than reflecting organic expansion across the market. Slator’s broader analysis of demand signals does not currently point to meaningful overall market growth.
The Index data shows:
- Growth is concentrated and consolidation-driven. A small number of Super Agencies account for a disproportionate share of expansion — often acquisition-led — while 57% of companies report declining revenues, making this the highest-variance segment.
- Headline growth masks widespread underperformance. While total indexed revenues of participating companies increased 8.2% to USD 10.3bn, 22.9% of firms reported declines, indicating significant dispersion beneath the aggregate figure.
- Growth is not evenly distributed across segments. Challengers (USD 8–25m) grew 11.6% and Super Agencies (USD 250m+) grew 10.4%, both outperforming the average, while Leaders (USD 25m–250m) lagged at 6.0% and Boutiques (USD 1–8m) grew 8.7%.
- Expansion is increasingly concentrated at the top. Super Agencies (~40% of the market) capture over 50% of total growth, while Leaders (~48%) account for only 35%, reinforcing a shift toward scale-driven consolidation rather than distributed growth.
The LTP landscape reflects rapid capability convergence rather than uniform revenue expansion. Most providers now span text, speech, and video, suggesting multi-capability platforms are becoming the default product model.
- Observed growth is concentrated in usage-based, workflow-embedded products. The strongest traction comes from platforms integrated into high-frequency workflows — such as meetings, events, and media — where consumption, not seat expansion, drives revenue, signalling a structural shift in monetisation rather than a broad uplift in demand.

How to Read the Index
Language Solutions Integrators (LSIs) are listed in order of revenue (USD, 2025), with each entry including year-on-year growth, headquarters, and ownership.
LSIs are grouped into four segments based on annual revenue:
- Super Agencies – full-service, standalone LSIs with revenues above USD 200m
- Leaders – LSIs with revenues above USD 25m (excluding Super Agencies)
- Challengers – USD 8m–25m
- Boutiques – USD 1m–8m
A separate segment captures emerging AI-first LSIs; early-stage companies below USD 1m revenue that operate with AI at the core of delivery, supported by productised or repeatable systems and clear market signals (e.g. traction, funding, or differentiated technology).
Language Technology Platform (LTPs) are displayed with key signals of adoption, usage, and commercial traction (such as revenue, customers, and platform usage) alongside company headquarters, buyer focus, and solution scope, offering a directional view of how language capabilities are built and scaled across use cases.

Data & Methodology
- Revenue & currency: Revenues are reported in USD for 2025 (USDm). Growth is calculated based on original reporting currency.
- Data sources: Data is primarily self-reported and sense-checked by Slator, with validation against public sources where available (e.g. financial reports, filings).
- LSI inclusion: LSIs provide revenue data for the prior two years and are segmented based on 2025 revenue.
- Emerging AI-first LSIs: Early-stage companies (<USD 1m revenue) with AI at the core of delivery, supported by productised systems and clear market signals (e.g. traction, funding, differentiated technology).
- LTP inclusion: Entries surface signals of adoption, usage, and commercial traction (e.g. revenue, customers, usage). Each company must provide at least one scale-relevant signal.
- Fiscal periods: Revenues reflect company fiscal years and may not align with the calendar year.
- Exchange rates: Based on year-end historical data.
- Missing data (*): Companies without 2025 revenue are included using latest available (2024) figures but excluded from growth calculations. Figures are updated as data becomes available.
