We had a really big issue early on with the software. We reached out to Grin and didn't get a response back until a few days later. Our account manager disappeared. Our sales person not responsible. They didn't fix the problem but changed how we received data from our influencer /Ambassador.

GRIN has so much to offer there is so much within the platform that I am still learning even after using it for over a year. They make communication with creators easy, have the most amazing connection with Shopify to make placing orders for creators so easy, and have reporting metrics on creator success that so many other platforms don't have. I would recommend it to any business trying to increase their influencer marketing efforts.

GRIN seamlessly interfaces with our Shopify store to generate and fulfill order for our influencer campaigns. Support is responsive if there is an issue. Overall the Shopify App works very well.

Having utilized GRIN for over 3yrs now, we've found it to be an indispensable tool in our influencer marketing arsenal. The platform is robust, offering a suite of features that cater to the needs of modern brands venturing into the dynamic world of influencer collaborations. GRIN allows us to efficiently manage our creator relationships. The ability to create activations, manage campaigns, and handle payouts all in one place is a huge time saver. Integration with Shopify is seamless, making it easier than ever to place orders and manage discount codes. Effective Communication Tools: The email templates and sequences simplify communication, allowing us to maintain consistency and professionalism in our interactions with influencers. Data Analytics: The platform provides comprehensive analytics that helps us track KPIs and measure the ROI of our campaigns accurately. This data is crucial for making informed decisions and strategizing future campaigns.

GRIN is the most useful, intuitive and comprehensive influencer management tool I've ever had the pleasure of using. It has made my job as Social Media Director so much easier and manageable! Between composing project briefs and setting up Activations to tracking content and paying out affiliates, I could not do my job as effectively without GRIN. I have been using it for years now and I will continue to use it as THE tool to support all my Creator Programs.

Overall a great software to keep things organized and structured. Makes it easy to build relationships with creators and follow up constantly. Would like for them to update a few bugs here and there but the support team helps out as best as possible!

A Master Class in Deception and Underperformance Grin deceived us throughout the sales process, hiding critical information, overselling the platform, and getting us to sign a 12-month contract with auto-payments that are impossible to stop, even when scammed. We're left with a tool that fails to meet our needs and doesn't deliver what was promised. Their "Curated lists" feature, touted as a white-glove service for creator search, is laughable. The team puts in minimal effort, delivering irrelevant or duplicate influencers. The promised robust discovery tool doesn't exist; they recently added a few search filters that are ineffective. Grin is a resource drain, creating problems instead of solving them. They excel at cold selling and misleading demos, coercing small businesses into a 12 month contract. The reality is far from what's promised. Avoid Grin and save yourself the frustration and wasted money. You'll likely end up trapped in a long-term contract for a product that fails to deliver.

Grin has been such a crucial key to not only execute our large gifting efforts, but to find new creators to work with. Our Grin rep has been super helpful and responsive in the rare cases we've had any issues. My favorite part is the Shopify integration that allows the creators to place the orders on their end. Love working with it!
