Pick GRIN if
you want to start free or at $200/month, avoid an annual contract, keep an unlimited CRM and let an AI agent do metered work on credits.
GRIN and Upfluence both run creator and affiliate programs for e-commerce brands, each with an AI agent (Gia and Jaice). GRIN now publishes monthly, credit-based plans from free to $1,000/month with no annual contract. Upfluence quotes per module with a 12-month minimum; Vendr reports a $15,000 a year median among its buyers.
The biggest difference today is commitment: GRIN is month to month with public prices, Upfluence is a year with a quote. Feature lists overlap more than they differ.

Facts come from each company's own pages, linked under Sources, checked 12 October 2026. Third-party figures are labelled with their publisher. Prices change, so recheck both before you buy.
GRIN's Growth plan at $500/month is $6,000 a year, and Scale at $1,000/month is $12,000, both cancellable monthly. Upfluence's typical annual contract, per Vendr, is $15,000, committed for 12 months. GRIN's older annual contracts, which Vendr still reports at a $27,150 median, predate its public plans.
Credits change the comparison. If Gia does a lot of work for you, you may need more credits than a plan includes; if you mostly use the CRM and affiliate links, which do not cost credits, GRIN's lower plans go a long way.
GRIN fits Shopify-led brands that want affiliates, codes and GMV tracking with flexible monthly billing. Upfluence fits brands that sell across several store platforms, want creators found among their own customers, and prefer a contracted platform with an account manager.
UGC Agent is a database of 28,000+ Instagram and TikTok UGC creators with public emails, plus an AI agent that searches live from a brief, UGC Brands and Creator Tracking.
