Episode notes
Crowdsourced Labeling From A Reward App
- Datumo began as a data-labeling startup in Seoul and built a reward-based app to crowdsource labeling from casual users.
- The CEO, David Kim, created the app to speed up slow labeling workflows and paid users for short labeling tasks.
Safety And Explainability Drive Demand
- Many companies feel unprepared to deploy AI safely, with 40% citing explainability as a significant risk in a McKinsey survey.
- Only a small fraction actively address these risks, creating demand for evaluation and benchmarking services.
From Labeling To Model Evaluation
- Datumo expanded from annotation into model evaluation and safety benchmarking as customers asked for scoring and comparisons.
- They now offer a no-code evaluation tool aimed at policy, trust, safety, and compliance teams.
