Overview
Flatkey gives developers access to AI models and tools through a unified API key and balance. Reporting says Flatkey and sister company Realset AI jointly announced a $10 million Series A on September 23, 2026 to expand real-world training data operations and Flatkey's multi-model platform. VCT does not assign the full $10 million exclusively to Flatkey.
Why Flatkey is interesting
Developer infrastructure plus real-world training data creates a useful AI-infrastructure entity, but the financing spans two related companies and should be modeled carefully.
