RakshaMany teams start with large, global vendors like TELUS International (now operating as TELUS Digital) for data collection and annotation, especially when speed and multilingual coverage matter.
But as you move beyond pilots into production, the “right” partner often changes. Regulated data, higher accuracy targets, tighter bias controls, and modern workflows like LLM evaluation or RLHF can all shift what you need from a vendor.
This guide breaks down the best TELUS International alternatives, with a practical way to choose based on modality, governance, and how much control you want to keep in-house.
How to Choose the Right TELUS International Alternative
If you’re comparing vendors, start by deciding which of these three “operating models” you want:
- Fully managed service: best when you need an end-to-end partner (recruiting, consent, collection, annotation, QA, delivery) and don’t want to build ops internally.
- Platform-first: best when you want to run labeling in-house (or with your own BPO), and you mainly need tooling, automation, and workflow control.
- Marketplace or participant panels: best when you want fast access to existing datasets or targeted human feedback, without standing up long-term labeling operations.
Then pressure-test each vendor on five buyer-critical areas:
- Data governance: consent, provenance, PII handling, retention, auditability
- Quality system: gold sets, multi-pass QA, reviewer training, disagreement resolution
- Security posture: access controls, isolated environments, vendor oversight
- Scale + coverage: languages, demographics, edge-case availability
- Delivery fit: annotation formats, integrations, SLAs, throughput predictability
1. Twine AI
Twine AI works as a hands-on partner rather than just a platform. Twine AI takes a hands-on approach to data projects, working closely with clients to deliver custom datasets across audio, text, image, and video. Rather than relying on open crowds, it curates a trusted global network of experts and manages every stage of the process, from recruitment and consent through to annotation and delivery.
This makes it especially strong in voice AI, computer vision and multilingual datasets, where accuracy and demographic diversity are critical. For companies working in regulated industries, Twine also embeds compliance frameworks like GDPR and CCPA directly into workflows.
- End-to-end service: From recruiting contributors, managing consent, and collecting raw data to annotating and delivering final datasets.
- Global reach: Curated network of contributors spanning multiple countries, languages, and demographics.
- Quality-first: Multi-step review pipelines reduce noise and bias.
- Key advantage: Strong in voice AI, computer vision and multilingual datasets, where accent, tone, and context matter for accuracy.

- Specialties: Handles LiDAR, geospatial, and multimodal datasets.
- Strength: Ideal for enterprises that want to own their data pipelines rather than outsource them.
10. Surge AI
As large language models (LLMs) grow in importance, Surge AI has positioned itself as a go-to provider for instruction-tuning, RLHF (reinforcement learning from human feedback), and evaluation sets. With a curated network of expert labelers, it specialises in tasks that require nuanced human judgment, such as ranking model outputs or aligning generative AI with human preferences.
- Focus: Instruction-tuning, RLHF, and evaluation sets for LLMs.
- Contributors: Vetted expert labelers with nuanced judgment.
- Strength: Best-in-class for alignment and safety-critical data in frontier AI.
- Why it matters: Generic crowds can’t deliver the subtle feedback needed for large language models.

Prolific is widely used by researchers and AI teams that need structured human feedback at scale. Its platform provides access to more than 200,000 vetted participants, allowing companies to collect preference data, run safety evaluations, or test AI outputs against targeted demographics. It’s particularly well-suited to projects where human response data — rather than just raw annotation — is essential.
- What it is: A platform to recruit high-quality participants for research and AI data tasks.
- Strengths: Targeted demographics, transparent worker pay, and strong academic/AI adoption.
- Best for: Collecting human preferences, feedback, and evaluation data quickly and reliably.
Conclusion
TELUS Digital remains a strong option for organizations that want a large, end-to-end AI data partner, but many teams get better outcomes by matching the vendor to the specific data risk and workflow they’re running, whether that’s multilingual speech collection, vision QA at scale, or LLM evaluation.
If you want a partner that can scope the dataset with you, recruit the right contributors, and run QA-heavy delivery without you building internal ops, Twine AI is designed for that “hands-on” model, especially across voice, vision, and multilingual data.
