Case study
On-site linguist deployment: 150 specialists in Tokyo.
An AI company needed language specialists on-site in Tokyo, working alongside its engineering team, where direct collaboration moved model refinement faster than a remote workflow could.

On-site linguist deployment
Project overview
What landed, and what made it hard.
An AI company needed Japanese-language specialists working on-site in Tokyo, embedded with its engineering team rather than delivering from a remote pool.
Delivery snapshot
On-site linguist deployment

- confidential AI company (on-site, Tokyo)
- Service
- On-site language specialists for model refinement
- Location
- Tokyo, on-site
- Scale
- 150 specialists deployed
Why this mattered
Outcome before process.
The goal was speed of iteration: model refinement moves faster when linguists and engineers can resolve questions in the same room.
The problem to solve
Why the work was difficult, and what MoniSa changed in-flight.
Remote workflows add a lag to every clarification, and model refinement depends on tight, repeated feedback between linguists and engineers.
The challenge
The problem to solve
Standing up 150 qualified Japanese-language specialists on-site, then narrowing to a steady production team, needed both reach and on-the-ground coordination.
Operating response
What MoniSa changed
MoniSa sourced and deployed 150 specialists on-site in Tokyo, then settled into a focused production team working directly with the engineering group.
- On-site deployment Specialists worked in Tokyo alongside the engineering team, not from a remote queue.
- Scale then focus A 150-person deployment narrowed to a steady production team as the work found its rhythm.
- Direct collaboration Linguists and engineers resolved questions in person, shortening the refinement loop.
Results
Measured outcomes from this engagement.
150 specialists were deployed on-site in Tokyo, settling into a steady production team that worked directly with the engineering group on model refinement.
| Location | Tokyo, on-site |
|---|---|
| Specialists | 150 deployed, steady production team after ramp |
| Focus | Model refinement with direct engineering collaboration |
| Outcome | Faster iteration than a remote workflow |
Selection logic
What protected the result.
The selection came down to whether MoniSa could source and review the work at standard, and whether that would hold across the full run.
Why the fit was real
Why the fit was real
The engagement needed on-the-ground reach to source 150 specialists in one city, plus the coordination to run them on-site.
What decided the result
What decided the result
On-site placement is what shortened the feedback loop between linguists and engineers.
What buyers can reuse
What buyers can reuse
- Some model-refinement work moves faster on-site than through any remote pipeline.
- Deploying at scale and then narrowing to a steady team kept the on-site program focused.
- The evidence keeps the client details confidential and attributes the metrics only to this engagement.

Multimedia services50 songs transliterated and synchronized across 9 Indian languages.
Song transliteration and sync
The challenge. A global short-video platform needed song lyrics readable and singable for non-native-script audiences.
What we did. MoniSa transliterated each song for faithful sound mapping and synchronized the text to the music.
The result. 50 songs made followable across 9 Indian languages, line by line in time with the audio.
Localization servicesA packaged-foods brand entered MENA markets with content ready for launch.
MENA market-entry localization
Problem. A packaged-foods brand needed labeling, marketing, and voiceover localized across three languages before a MENA launch.
Action. MoniSa ran labeling, brochures, marketing, and voiceover as one coordinated program against the launch window.
Result. 150,000 words and 40 hours of voiceover localized across Arabic, Kannada, and Malayalam for market entry.
Translation servicesAlmost 150,000 words of Arabic delivered in a 20-day batched sprint.
Arabic content sprint
Problem. A global ride-hailing platform needed 147,916 words of Arabic translated inside 20 days.
Action. MoniSa sourced for throughput and shipped in reviewed batches across the 20-day window.
Result. 147,916 words delivered across a 20-day window in reviewed batches, landing in stages rather than one final hand-off.

The answers most briefs open by asking for.
Buyers rarely start with who we are. They start with a list of fields to fill. Here are ours, so the first email can be about the work instead.
- Languages and locales
- 300+ languages and 4,500+ dialects, quoted per locale rather than per language — because the dialect decides whether a dataset is usable, whether a market accepts a release, and which specialist the work goes to.
- Specialist network
- 110,000+ verified language specialists — linguists, annotators, and reviewers — plus voice talent and subtitlers, matched to the language, domain and task before assignment.
- Capacity and mobilisation
- Named availability confirmed per pair before scoping. Coverage is reported as staffed today or needing a recruitment window, in writing, before a launch date or release window is agreed.
- Sourcing constraints
- Specialists can be sourced against geographic, residency, locale and demographic requirements — including native-only, in-country, and speaker-diversity quotas where a data programme demands them.
- Deliverables and specs
- Work is delivered to the receiving specification: structured formats and schemas for data and annotation work, and timed-text, audio and platform conformance for media — subtitle reading speed, line limits, cue timing, channel and sample-rate requirements included.
- Comparable work
- 62 documented case studies stating the scope, the constraint that made it difficult, and the measured result — across AI data programmes, partner overflow, and media releases. 2,000+ AI projects delivered and 1,000+ brands served since 2015.
- Certifications
- ISO 9001:2015 quality management, ISO 27001:2022 information security, and ISO 17100 translation services — scoped to translation specifically, and stated that way rather than implied across every line.
- Commercial basis
- Quoted in the unit the work is measured in — per word, per audio hour, per approved hour, per finished minute, per batch, per item — with what the unit includes stated alongside it, whether the quote is for you or for a client you quote onward.
Need this against your own template? Convert your scope between units and check the deadline, then send the brief with your language list, content type, volume and deadline, and the acceptance criteria you will judge the output against — those four decide feasibility, and the reply addresses them directly.
