Bloom is brand infrastructure that serves as the brand layer for agents. It ingests brand materials from sources like websites, decks, Figma, and social media, systematizes them into a canonical brand ontology, and enables generation of on-brand assets through an API, web app, and MCP interfaces. Since launching v1 in December 2025 the company says it has generated over 175,000 on-brand assets for customers. Bloom is part of Y Combinator's Spring 2026 batch.
