GRIN

GRIN is an influencer marketing platform for discovering creators, managing campaigns, measuring performance, and handling creator payments. Instagram is its listed social channel. The service is available on the web, iOS, and Android. Its free plan includes 200 monthly credits, requires no card, and is described as the trial rather than a trial with a clock. Paid subscriptions are month-to-month and not priced per seat: Starter costs $200 per month for 2,000 monthly credits; Growth is $500 per month for 7,500 credits and up to 100 active creators; Scale is $1,000 per month for 20,000 credits and up to 250 active creators; and Complete is $1,500 per month for 30,000 credits and up to 500 active creators. GRIN was founded in 2017 and is headquartered in Sacramento, California. The listed capabilities cover the main campaign workflow, from finding creators through performance analysis and payment management, while the credit and creator limits differ across its plans.

GRIN covers creator discovery, campaign operations, performance tracking, and payments for Instagram. Compare plan credits and active-creator caps with the scale of your campaigns.

GRIN suits teams running Instagram creator campaigns that need creator discovery, campaign management, analytics, and payments. The free plan may fit users who want to start with 200 monthly credits.

Overview

GRIN combines creator discovery, campaign management, performance analytics and creator payments in a platform focused on Instagram. It is made by GRIN, a Sacramento-based company founded in 2017.

The central trade-off is clear: the platform brings several campaign tasks together, but the supported social channel is limited to Instagram. For a wider category comparison, see our Influencer Marketing Platforms list.

Key features

Discovery, campaign management, performance analytics and creator payments cover distinct stages of an influencer campaign, from finding creators through coordinating work and measuring results. That breadth suits teams looking to manage those activities in one platform. Instagram-only channel support makes GRIN a less fitting choice for teams whose programs depend on other social networks.

Pricing

GRIN uses a freemium model. The Free plan costs nothing and provides 200 monthly credits. It requires no card and has no trial clock, but it is the trial itself—not a separate ongoing free tier—so it is best for evaluating the service rather than sustaining a continuing campaign workload.

Starter costs $200 a month, billed month-to-month, and includes 2,000 monthly credits. It has no stated active-creator cap, but the credit allowance is the smallest paid allocation. Growth costs $500 a month, billed month-to-month, and raises the allowance to 7,500 monthly credits with up to 100 active creators. That cap gives a defined operating scale, though teams exceeding it would need a higher tier.

Scale costs $1,000 a month, billed month-to-month, for 20,000 monthly credits and up to 250 active creators. Complete costs $1,500 a month, billed month-to-month, and provides 30,000 monthly credits with up to 500 active creators. These higher plans make more sense for larger programs that can use both the expanded credits and roster capacity; smaller teams may not need to pay for that headroom. Paid plans are not priced per seat, so the stated monthly prices do not vary by seat count.

GRIN’s free trial is the Free plan, while each paid tier is month-to-month. The practical buying questions are whether the monthly credit allowance matches expected activity and whether the active-creator ceiling on Growth, Scale or Complete accommodates the roster.

Platforms

GRIN is available on web, iOS and Android. Platform availability is broad, while its social-channel support remains Instagram.

Who it's for

GRIN is best suited to teams running Instagram creator programs that want discovery, campaign operations, performance tracking and creator payments together. Its paid tiers provide progressively larger credit allowances and, from Growth upward, explicit active-creator capacities.

It is a weaker fit for cross-channel programs that need confirmed support beyond Instagram, or for buyers seeking a free plan for ongoing work: the no-cost offer is a trial with 200 monthly credits.

Pros and cons

• Pros: Discovery, campaign management, analytics and creator payments sit within one platform, covering several campaign needs.
• Pros: A no-card, no-clock trial offers 200 monthly credits, allowing evaluation without an immediate paid commitment.
• Pros: Paid plans are month-to-month and not priced per seat, with higher tiers spelling out active-creator limits.
• Cons: Instagram is the only supported social channel identified, limiting its fit for programs spanning other networks.
• Cons: The free offer is the trial, not a continuing free tier, and its 200 monthly credits constrain ongoing use.
• Cons: Growth, Scale and Complete cap active creators at 100, 250 and 500 respectively, which may constrain larger rosters.

Alternatives

Billo is worth comparing for video-ad creator content: its Video ads plan is billed from $99 per video, while its free plan includes 8 AI scripts and 3 AI mashup credits per month.

Kleos offers a free-forever plan with unlimited creator records; choose it if that record allowance is a priority. Its Starter plan costs €499 a month, with prices excluding VAT.

JoinBrands has a pay-as-you-go option with a 15% platform fee and $0 Roll Over Cash, plus a $99 per month Start-up plan with a 12% platform fee. It may suit buyers comparing fee-based creator campaigns with GRIN’s monthly credit tiers.

Intellifluence has a free plan for testing influencer marketing with flat-rate influencer services, limited to 1 user, 1 campaign and 5 marketplaces.

LTK offers a Launch plan at $99 a month, billed monthly, with 10 creators per month, a $25,000 annual collaboration-spend limit, 1 user seat and 1 brand promoted. It is a more relevant comparison for buyers whose needs fit those explicit creator, spend and seat limits.

Infloq starts at $19 a month for 5,000 influencer profiles per month, 5 active campaigns, 3 team members and 10 videos per month. That tier may appeal to teams prioritizing a lower monthly entry price and those stated quotas.

Humanz is another paid influencer-marketing option to consider.

Growi starts at $269 a month, billed annually, and includes 1 commerce channel, 10,000 outreach messages per month, 25 managed creators, 50 AI analyses per month and 300 post downloads per month. It is worth comparing for buyers seeking those outreach and commerce-oriented limits.

Verdict

Choose GRIN for an Instagram-focused creator program that benefits from discovery, campaign management, analytics and payments in one platform, with paid capacity that scales by credits and active creators. Look elsewhere if you need confirmed support beyond Instagram, or if you require an ongoing free plan rather than a trial.
