About
Grin is a creator management platform built specifically for e-commerce and direct-to-consumer brands that run influencer and creator marketing programs at scale. Founded in 2014 and headquartered in Sacramento, California, Grin has raised more than $110 million and positioned itself as the operating system for creator programs — managing the full lifecycle from discovery through gifting, contract management, content approval, payment, and performance analytics within a single platform. The company's deep integration with e-commerce platforms like Shopify, Magento, and WooCommerce sets it apart from generalist influencer platforms by enabling direct product gifting workflows and affiliate conversion tracking tied to actual sales.\n\nGrin's platform provides a creator discovery database with filtering by audience demographics, engagement rates, and social platform; relationship management tools that centralize all communication and collaboration with creators in one place; product gifting automation that connects to Shopify or other e-commerce platforms to send products to creators without manual order management; content rights management and approval workflows; and analytics that track reach, engagement, and sales conversion metrics at the campaign and individual creator level. The CRM-style relationship management capability is particularly valued by brands that maintain ongoing long-term partnerships with a roster of brand ambassador creators.\n\nGrin competes with AspireIQ, Mavrck (now Later), CreatorIQ, and Traackr in the creator marketing platform space. Its deep e-commerce integration and focus on DTC brands have given it a strong position among Shopify merchants and consumer brands that treat creator marketing as a primary customer acquisition channel rather than a supplementary brand awareness tactic.
