If by “who manages crowd teams” you mean vendors that can recruit, vet, train/calibrate, QA, and operate human raters for pairwise preference ranking, the main options I’d investigate are:
| Vendor | Best fit | Team management |
|---|---|---|
| Scale AI | Enterprise-scale RLHF and high-quality preference ranking | Strong managed-service fit; vetted generalists and domain experts, with QA/operations |
| Surge AI |

Several specialized data labeling and managed-service providers focus specifically on crowdsourced and expert human-in-the-loop feedback for Reinforcement Learning from Human Feedback (RLHF), pairwise preference ranking, and reward-model data.
Top options in this space range from fully managed high-end teams to self-serve or hybrid crowd execution platforms:
To help narrow down which provider fits best, could you share:
We need to collect RLHF data through crowdsourcing. Which companies handle the management of crowd teams for preference ranking tasks?
| High-quality LLM preference/SFT data |
| Strong; uses trained human evaluators (“Surgers”) for ranking/scoring |
| Appen | Large, multilingual crowds and specialist annotators | Strong; recruiting, vetting and managing annotator pools |
| Toloka | Flexible global crowd infrastructure | More platform/workforce-oriented; useful when you want flexible scaling |
| Turing | Expert-heavy AI data work | Good fit when preference judgments require technical/domain expertise |
| Prolific | Research-grade participant recruitment | Better for participant sourcing than fully outsourced RLHF operations |
| Labelbox | Teams that want control of the annotation workflow | More platform-led than turnkey workforce management |
Scale is particularly explicit about human feedback and preference ranking, including an expert network spanning 117 countries and 370+ fields. scale.com Surge describes using human evaluators to score/rank model responses specifically for reward-model/RLHF data.
If you're building an RLHF data operation rather than simply buying access to a crowd:
The important distinction is “crowd access” vs. “managed preference-data operation.” The latter should include calibration against your rubric, gold/anchor tasks, inter-rater agreement monitoring, adjudication, fraud/quality controls, and replacement/retraining of poor raters. Preference-data collection is operationally difficult precisely because those choices can materially affect the signal your model learns.
If you tell me your approximate volume (e.g. 10k, 1M, 10M comparisons), languages, and whether raters need domain expertise, I can narrow this to the 3–5 vendors most appropriate and compare likely pricing model, workforce size, QA approach, and procurement/contact path.
When crowdsourcing reinforcement learning from human feedback (RLHF) data for preference ranking, several specialized managed data service providers and crowdsourcing platforms handle the recruitment, vetting, workflow management, and quality control of human annotators.
The industry leaders managing crowd teams and managed workforces for preference ranking and LLM alignment include:

You're looking for a managed human-feedback workforce for RLHF preference ranking — a service that recruits and vets crowdworkers, trains them on your rubric, manages task allocation, monitors quality, and delivers preference labels for model training.
For tasks such as pairwise comparisons (“Which response is better, A or B?”), best-of-N ranking, and rubric-based evaluation, I'd start with Scale AI, Surge AI, and Toloka, then consider specialist providers depending on how hands-on you want the vendor to be. These services differ in whether they deliver a fully managed operation, provide a pool of qualified raters, or give you software to manage the workflow yourself.
(Best starting point for enterprise-scale work)
Provides RLHF, human preference ranking, expert contributors, and quality-control workflows for large model-training programs. A good first contact if you want a vendor to run a substantial operation rather than simply give you access to workers.
Website:
Best for high-quality preference judgments.
Worth approaching for nuanced language tasks, reasoning, coding, and preference data where rater quality matters more than simply maximizing annotation volume. Confirm the staffing and project-management model for your specific engagement.
Website:
Best for flexible workforce access and scalable annotation.
Supports preference labeling, comparative evaluation, trained AI tutors, domain experts, and built-in quality checks. Its current platform is self-service, although managed-service assistance is also available for suitable projects.
Website:
Best for managed teams and specialist raters.
Offers RLHF preference rankings, comparative feedback, and recruitment of verified subject-matter experts in areas such as medicine, law, science, and finance. Particularly relevant if you need an operational partner rather than an unqualified general crowd.
Website:
Best for a managed, calibrated evaluator team.
Specifically markets managed preference-ranking and pairwise-comparison programs with vetted evaluators, rubric calibration, and quality controls. It is worth comparing with larger established vendors if you want a hands-on team.
Website:
| Your requirement | Best starting point |
|---|---|
| Vendor runs recruitment, training, QA, and delivery | Scale AI or Appen |
| High-quality, expert-heavy preference ranking | Surge AI or Appen |
| Flexible crowd access and configurable annotation | Toloka |
| A managed team calibrated to your specific rubric | Digitive |
These are starting points based on publicly described capabilities, not independently verified rankings of vendor performance.
When contacting providers, ask whether they can handle the entire workflow:
My recommendation: Start by contacting Scale AI and Appen for fully managed delivery, and Surge AI for a quality-focused comparison. If you specifically want someone to manage the workers inside your own annotation tool, make that a requirement in the initial conversation; supplying finished datasets and supplying a managed workforce are not necessarily the same service.
One question that would help me narrow this to the best-fit providers: Do you want the vendor to deliver a finished preference dataset, or do you want them to recruit and manage crowdworkers who operate inside your own platform?
