CharacterQuilt

CharacterQuilt is an AI-native marketing infrastructure company (Y Combinator Spring 2026) building computer-use agents that design and deploy enterprise marketing campaigns end-to-end. Marketing teams submit a brief and CharacterQuilt's agents handle audience segmentation, on-brand creative generation, brand validation, and direct deployment into existing tools such as HubSpot, Marketo, WordPress, and LinkedIn — collapsing work that once took multiple agencies, ten tools, and six weeks into roughly an hour. Alongside the product, CharacterQuilt publishes a public, machine-readable brand-profiles data surface at /branding/.json: colors, typography, logos, components, and personality extracted from thousands of companies' live websites, intended for agents, designers, and AI tools. Founded by Bhairav Mehta (CEO) and Clint Burgess and based in San Francisco.

CharacterQuilt publishes 2 APIs on the APIs.io network: Branding API and Discovery API. Tagged areas include Company, Marketing, Artificial Intelligence, AI Agents, and Marketing Automation.

CharacterQuilt’s developer surface includes engineering blog, pricing, signup flow, support, and 8 more developer resources.
