Overview

Grin, Inc. sells GRIN, a creator marketing platform for brands. It covers finding creators, running gifting, affiliate, paid and UGC programs, and paying creators from a funded escrow wallet.

For Shopify brands

  • Connects to Shopify in one click, and custom or headless stores connect through the API.
  • Runs gifting, affiliate, paid and UGC programs from one platform, with affiliate links, codes and commissions on every plan.
  • Takes over creator search, outreach drafting, contracts, escrow and payouts, and tracks posts with impressions and engagement.

How it works

A brand tells Gia what it wants, and Gia finds matching creators, builds the program and drafts the outreach for the team to review. The brand chooses how hands-on to be, funds a wallet to pay creators, and GRIN holds creator fees in escrow until payout. Setup of a first campaign can take as little as 10 minutes.
