Data Annotation Services
Wherever AI models require training data, human judgment still wins.
We’ve annotated datasets across model types. Consistent across annotators and data types. Your labeling backlog isn’t a backlog.
Labels, bounding boxes, transcriptions, classifications, entity tags—data annotation creates the ground truth that AI learns from. Annotation tools help scale, but they can’t ensure the quality that model performance requires.
Before you outsource anything, we’ll walk through your current operations with you and assess:
Where automation genuinely helps
Where human judgment is required
Whether outsourcing makes sense & how to do it cleanly
The Real Problem
Most teams don’t struggle to collect data. They struggle to annotate it accurately and consistently.
Automation generates speed, but it also generates risk
Annotation quality varies by annotator
Labeling guidelines are ambiguous
Edge cases require judgment
Quality assurance is time-consuming
When model performance depends on data, “labeled” isn’t the same as “accurate.”

Your Operations May Be Different—That’s Fine
Most of our client work is bespoke. The categories above reflect our core expertise, but we’re always open to custom requirements. If your operations share the same fundamentals—high volume, real stakes, and the need for human follow-through—we should talk.

Why Assivo
Founded in 2017, Assivo applies the rigor of institutional finance and strategy consulting to outsourced operations, with a focus on clear accountability, fixed-price commercial structures, and outcome-oriented delivery. As an independent, privately held firm, Assivo structures partnerships around client priorities, emphasizing continuity, transparency, long-term relationships, and client integrity.
Accuracy-first Execution
Every deliverable passes through multi-layer quality review before it reaches you. We measure in defect rates, not just throughput.
Strategic Human-in-the-Loop Governance
Automation handles volume. Human judgment handles exceptions, edge cases, and the decisions that affect outcomes.
Managed Teams, Not Seat-based Staffing
You get a trained team that learns your processes, not a rotating pool of contractors. Our annual turnover is ~15%—a fraction of the 50% industry average. Continuity drives quality.
Offshore Efficiency, Onshore Standards
Our global teams operate under U.S.-caliber management, documentation, and accountability structures.
Clear Accountability from Intake to Output
