Snorkel Flow

Snorkel AI's commercial data-development platform: programmatic labeling and weak supervision (heuristic and LLM-generated labeling functions), plus curation, slicing, filtering, and fine-tuning/evaluation data workflows.

Snorkel Flow, proprietary enterprise platform (distinct from the Apache-2.0 snorkel-team/snorkel OSS library, which is stale: last release 0.10.0, Feb 2024). Confirmed 2026-07-21. ~$237M raised, ~$1.3B valuation (Series D, May 2025); enterprise/government rather than frontier-lab customers.
