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 Pipeline.
