Expert-Led Data Annotation, RLHF & Model Evaluation for AI Teams

SyncSoft.AI delivers end-to-end AI training data: data collection and generation, data annotation (image, text, video, LiDAR, multimodal), RLHF and reasoning-data workflows, model evaluation and benchmark dataset creation, plus AI automation integration. All services are executed by bilingual (English/Vietnamese) SME-led teams in Vietnam.

SyncSoft.AI targets a different economic tier: our Vietnam-based teams deliver comparable quality (99%+ inter-annotator agreement on benchmark tasks) at 30–40% less than US vendors and 10–15% less than India-based competitors. We specialize in healthcare, software/code, and financial datasets. Our founder team has over a decade in IT outsourcing and AI operations.

Yes. Our Reasoning & Human Feedback Data service covers preference ranking, agent trajectory correction, tool-use validation, multi-turn dialog evaluation, and SFT dataset curation. We have run projects with both open-source LLM teams and enterprise AI labs.

Every project runs triple-pass QA: primary annotator, peer review, and SME final audit. We publish inter-annotator agreement metrics per delivery. For healthcare and finance, annotations are reviewed by domain-credentialed reviewers. Spot-check audits are included at no extra cost.

We are tool-agnostic. Teams have worked on CVAT, Label Studio, Labelbox, V7, SuperAnnotate, and proprietary client tools. For complex multimodal or agentic data, we can build a custom annotation UI on AWS (Next.js + Lambda + S3) within 1–2 weeks.

Healthcare (medical imaging, clinical text, EHR), Software & Code Intelligence (multi-language code annotation and evaluation), Finance (transaction labeling, fraud, document AI), Automotive/ADAS (LiDAR, edge-case mining), plus retail, media, logistics, robotics, and agriculture datasets.

A pilot of up to 5,000 data points typically kicks off within 5 business days of contract signing. Full production engagements start in 2–3 weeks including SME recruitment, tool setup, and annotation guidelines review.

We operate under strict NDA and data-handling policies modeled on SOC 2 Type II. ISO 27001 certification is in progress for Q3/2026. For HIPAA-covered healthcare engagements, we follow project-specific safeguards agreed in the BAA.

Yes. Our Model Evaluation service covers benchmark dataset creation, response scoring with rubrics, hallucination detection, adversarial prompt development, and regression-test packs. We have delivered evaluation suites for both chat LLMs and tool-using agents.
