Isidor

Isidor is a frontier enterprise-AI company, founded in 2025 and headquartered in San Francisco with a London presence, building secure, vertically-integrated data pipelines that transform unstructured proprietary enterprise data into training- and evaluation-ready material for foundation models. Its platform spans five capabilities it describes as evaluation (industry-specific and agentic benchmarks), verifiers for generative-AI outputs in critical workflows, reasoning-trace data capture, foundation-model post-training (fine-tuning and alignment on proprietary data), and enterprise-grade security and privacy. Isidor raised an oversubscribed $3.6M pre-seed led by Gradient Ventures, futurepresent, and Seedcamp, with angels from Google DeepMind, Perplexity, and others. The company has no public API or developer surface yet; this profile tracks it as an enrichment lead in the API Evangelist network.

Isidor is profiled on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Enterprise AI, Machine Learning, and Data Pipelines.
