Overview

Rapidata is an AI infrastructure company that helps organizations collect high-quality human feedback for training, evaluating, and improving artificial intelligence models. As modern AI systems increasingly rely on reinforcement learning from human feedback (RLHF), preference testing, and model evaluation, obtaining reliable human judgments has become one of the biggest bottlenecks in AI development. Rapidata addresses this challenge by providing an on-demand platform that enables AI companies to gather large volumes of human feedback in hours instead of weeks.

The company's platform distributes short, opt-in evaluation tasks through a global network of digital channels, allowing millions of participants to provide annotations, rankings, preference data, and validation feedback at scale. This approach eliminates many of the operational challenges associated with traditional data labeling vendors while significantly reducing the time and cost required to collect high-quality training data. Rapidata supports use cases including model evaluation, reinforcement learning from human feedback, dataset validation, quality assurance, and continuous AI improvement for foundation models and enterprise AI applications.

Founded by Jason Corkill, Marian Kannwischer, Luca Strebel, and Mads Alber, Rapidata is building infrastructure that treats human intelligence as a scalable resource for AI development. Its platform is already used by AI labs and technology companies to accelerate model iteration and improve output quality across text, image, video, and multimodal AI systems. By shortening feedback cycles from months to days—or even hours—Rapidata enables organizations to develop more capable AI products while reducing operational complexity and speeding up deployment.

How Rapidata Works

01
STEP 01

Install SDK

Developers install Rapidata's Python SDK or connect through its API to integrate feedback collection with existing AI data and model pipelines.

02
STEP 02

Define Task

Users create a job definition containing the AI output or data to evaluate, along with instructions, evaluation criteria, context, and feedback format.

03
STEP 03

Select Audience

The platform routes tasks to relevant audiences based on language, geography, and specialized task requirements.

04
STEP 04

Collect Feedback

Human participants complete comparisons, rankings, classifications, or scoring tasks and submit structured responses.

05
STEP 05

Receive Results

Rapidata returns processed feedback as annotated datapoints, preference data, and rankings through its API for use in model training, evaluation, or benchmarking workflows.

Platform Evaluation

Platform Strengths

  • Provides human feedback through an API instead of requiring teams to manually manage annotation workforces
  • Supports high-volume model evaluation, ranking, comparison, and preference-data collection workflows
  • Allows teams to target feedback audiences by language, geography, and relevant task expertise
  • Integrates with existing AI development pipelines through Python SDK and API-based workflows
  • Returns structured feedback datasets that can be directly used for model training, evaluation, and benchmarking
  • Includes validation-based quality controls where annotators are pre-screened and continuously scored against quality tasks

Current Limitations

  • The platform is designed primarily for AI feedback, annotation, evaluation, and model training workflows rather than general-purpose survey research
  • Feedback quality and relevance depend on how clearly users define task instructions, context, audience targeting, and evaluation criteria
  • Organizations handling highly sensitive information may need to review whether their data can be included in externally distributed human-feedback tasks
  • Some advanced workflows, such as real-time RLHF, may require technical integration with existing AI model pipelines
