Datacurve

Datacurve is a San Francisco-based AI infrastructure company that positions itself as "the data engine for frontier AI," building high-quality, expert-annotated datasets, reinforcement-learning environments, long-horizon agent tasks, benchmarks, and supervised fine-tuning demonstrations used to train and evaluate frontier AI models. Its offerings include off-the-shelf and custom datasets, agent-trajectory capture (tool calls, pivots, recovery attempts), and domain-sensitive evaluations across software engineering, data science, cybersecurity, machine learning, and research. Datacurve is backed by Homebrew and publishes research such as the DeepSWE long-horizon coding benchmark. The company sells through direct engagement (contact@datacurve.ai) and currently exposes no public API, developer portal, or SDKs.

  notes: Enrichment probed the site plus the well-known and package-registry surface. Datacurve has no public API, developer
    portal, docs, SDKs/packages, or event surface, so most artifact types are N/A (not penalized). Only the domain-security
    probe and an identity/discoverability pass yielded real data.
