The bug bounty platform built for AI and ML security
Time-boxed hacking challenges targeting LLM assistants, agentic systems and model artifacts, each with explicit objectives and rules.
Compete over a fixed window to climb public rankings and win real cash prizes for top placements.
After a challenge closes, outcomes and techniques are shared so the community can learn from each exploit.
Research coverage extends to ML supply chain targets such as Keras model deserialization and TensorFlow Lambda exploits.

Turn human expertise into frontier-grade AI training data
A purpose-built engine that converts raw expert input — audio, video, text and decisions — into structured training data, alignment signals and evaluation sets at scale.
A global workforce of domain specialists, linguists, researchers and voice actors who generate the human judgment that synthetic data cannot approximate.
Open leaderboards for conversational speech-to-text (WER/CER) and speaker diarization (DER), published with technical reports, datasets and an open-source harness.
Preference data, rewards and task environments plus rubrics so teams can fine-tune and post-train models on realistic, expert-graded behavior.
