Trusted by leading AI and tech companies across industries
Our Core Human Data Expert Services
Sourcing and Onboarding
We deploy AI trainers, AI engineers, and human expert data with domain and language expertise to train and fine-tune models
Quality Assurance
Every project includes multi-level reviews, feedback loops and accuracy tracking to ensure consistent, high-quality results.
AI Trainer Support
Experienced trainers provide model evaluation, feedback generation, and reinforcement optimization.
Scalable Delivery
Easily scale your AI training teams up or down based on model complexity and project timelines.
Multimodal AI Training
Our experts support code based LLMs to enhance performance across NLP, conversational AI and multimodal systems.
Types of AI trainer you can hire
Conversational Trainer
They focus on training chatbots, voice-agents, and conversational AIs refining how the system understands input, how it responds, shaping dialogues.
Model Fine-Tuning Trainer
They take a pre-trained model (e.g., LLM) and adapt it to a specific domain (finance, healthcare, legal, recruitment), fine-tune, test, refine.
Evaluation Trainer
They monitor AI outputs, test edge cases, identify biases, inaccuracies, bad behavior, feed that back into training cycle.
Multimodal / Image-Video / Voice Trainer
They train models on non-textual modalities—image recognition, audio/speech, video/gesture, etc. They may annotate visual/audio content and train models accordingly.
Domain Expert Trainer
They bring expertise in a specific industry (healthcare, legal, finance, recruitment) and help train the AI with domain-specific data, terminology, context, and rules.
Human-in-the-Loop Trainer
They provide direct human feedback to the model: correct outputs, supervise model decisions, manage a loop where humans review and refine model behaviour.
