Managed Engagements
From Scoping Call to Production Data in Weeks
Enterprise programs follow a pilot-first process, so you validate quality and throughput before committing to scale.
Scope
We map your data spec, quality bar, volume, and timeline, then design the sourcing, screening, and task workflow to match.
Pilot
A fixed-scope pilot with defined quality gates. You review real deliverables against your acceptance criteria before scaling.
Scale
Production throughput with continuous quality monitoring, calibration cycles, and a dedicated program manager.
Iterate
Specs evolve as models improve. We recalibrate cohorts, rubrics, and workflows alongside your research roadmap.
Multimodal Data Collection
Beyond Text: Audio, Video, and Real-World Capture
Frontier and physical AI need more than survey responses. Connect's participant pool records, uploads, and annotates rich media at scale, including duration-based video for embodied, egocentric, and robotics training data.

Templates
AI Training Projects In Minutes
With Connect Templates, easily set up your AI training tasks in a matter of minutes through our intuitive and modern interface. Simply upload your data and Connect will create all the individual tasks necessary to complete your projects, from data labeling to form collection. Our project templates include:
Data Labeling/Media Annotation
High-quality participants are essential for data labeling and media annotation projects as they ensure precision, accuracy, and consistency in the labeled data. Their deep understanding of project requirements and annotation guidelines minimizes errors and leads to reliable datasets. Using Connect Templates, you will have full control over how many pieces of individual media you want our participants to label – whether it's 1 or unlimited tasks.
Custom HTML Projects
For Advanced Users
For advanced users who have a data set that comprises tasks that they want to fully customize the form-collection to our participants, our custom HTML Project template is a perfect fit! You can upload datasets that will be available to inject into your HTML powered project form.

FAQ
Frequently Asked Questions
Anything with a human in the loop. Teams run data labeling and media annotation, model evaluation, RLHF and preference data, SFT and prompt writing, red teaming, and multimodal collection, either as one-off projects or as standing pipelines. You can start from a built-in template, upload a custom HTML task, or point participants at any tool you already host.
Managed vendors are a black box. Data goes in, deliverables come out, and you never see who did the work. On Connect you work directly with a continuously vetted participant pool, self-serve or through the API, and you control targeting, task design, and approvals yourself. When you want end-to-end delivery, our managed team runs that same transparent pipeline for you. You get vendor-grade delivery without vendor lock-in.
Yes. Managed programs cover scoping, task and rubric design, participant sourcing and screening, and pilot delivery with defined quality gates, then move into production with a dedicated program manager. Request a demo to scope a program.
Every participant clears Sentry®, our patented behavioral screening, before they see a single task, and the vetting continues from there. Identity and device checks, engagement monitoring, and a two-way reputation system run in the background, and you review submissions before approving them. In an independent Nature Human Behaviour comparison of nine opt-in panels, Connect participants ranked first for response quality.
AI-content detection runs on submissions, and participants flagged for AI use face consequences up to removal from the pool. Together with behavioral screening and the reputation system, this keeps model-generated answers out of your training and evaluation data. On platforms without continuous monitoring, that kind of contamination is a growing problem.
The pool is vetted, highly engaged, and profiled on more than 100 attributes covering demographics, occupation, education, and technical experience. Quotas and one-click census matching are free. For expert work, run a qualification task to build a screened cohort of nurses, attorneys, engineers, or whoever your rubric requires, or have our managed team source them for you. Waves recontact brings the same people back across sessions at an 80% return rate.
If your task runs at a link, Connect can staff it. Teams pair Connect with Label Studio, Labelbox, SuperAnnotate, HumanSignal, Datasaur, Potato, and their own internal tools. For recurring pipelines, the Human Data API automates project creation, participant management, and payouts. View integrations.
Template projects go live in minutes, and data usually starts arriving within minutes to hours. Many self-serve datasets finish within a day. Managed programs run pilot first, with initial deliverables arriving within weeks of scoping depending on how specialized the cohort is.
You set participant pay and Connect adds a transparent platform fee. There are no subscriptions to get started, and targeting, quotas, and census matching are always free. We enforce fair-pay minimums, and paying above them is the cheapest data-quality upgrade available. Managed and enterprise programs are scoped to the work, pilot first. Talk to our team for volume pricing.
Yes. CloudResearch is SOC 2 Type II certified, Microsoft SSPA compliant, and TX-RAMP certified, and we support custom MSAs, DPAs, and security review. Consent, licensing, and provenance are built into every collection, including multimodal capture. Visit our Trust Center for details.
