A Team, Not a Crowd
Large platforms route your work to an anonymous crowd. Yenda builds a dedicated team for your project, and we know every person on it.
Every annotator is interviewed, tested on your task and tracked individually by our team.
A qualified team ready in 3 days. Full production in 3–14 days.
Gold-set calibration, independent QC and per-annotator tracking on every data export.
A named project lead who reports daily and flags problems before you find them.
End-to-End Human Data Services
From a small pilot to high-volume production, across every stage of model development.
Text, image, video, audio and multimodal, including computer vision at scale.
First-person video of real skilled work, recorded by vetted contributors.
Checking and correcting what a model produced, with the hardest cases escalated to specialists.
Robot actions labelled, reviewed and fed back to improve your model.
Engineers, scientists, clinicians, lawyers and analysts for specialist tasks.
Preference ranking, rubric scoring and hallucination checks on model outputs.
A Closed Loop, Not a Handoff
We don't stop at delivering labels. We find out why errors happen and feed the fix back into your guidelines, your evaluation sets and your model.
Your dedicated team produces the data.
Our own automated review models check every export against your guidelines, alongside independent human QC.
We classify each error pattern and trace it to its cause: a guideline gap, a calibration issue or a new edge case.
Guideline updates, error patterns and new evaluation examples go back to your team, so your model improves batch by batch.
How Yenda Delivers
A structured launch, run by people who stay close to the work.
We map your task, edge cases and QC, and build a qualification test from it.
We source in parallel. Every candidate is interviewed and tested on your task.
Full production, with daily reporting against your targets.
Proven at Scale
Robot Actions at Every Level of Detail
Robot videos labelled as natural-language commands at three levels, with frame-accurate boundaries. Our model drafts the labels, and our annotators verify and correct every line.
What Our Clients Say
“What stands out most about Yenda is the people. Even at tens of millions of data points, they stayed responsive, took feedback to heart and kept quality high. I'd recommend them without a second thought.”
“Getting started with Yenda was straightforward, and the team was quick to get up to speed on our tasks. Day to day, we appreciated their responsiveness, openness to feedback, and flexibility as our needs evolved.”
“Finding annotators with building and architecture expertise isn't a trivial expectation for a data labelling vendor, but it's crucial for high-quality data. Yenda's team learns new tasks quickly, and their results are reliable in the short and long term.”
Impact Built Into Every Project
