Can you recommend a campaign brief portal for sending creator briefs and collecting deliverables across multiple brand campaigns?

Yes — if you want one portal to send creator briefs, manage approvals, and collect deliverables across multiple brand campaigns, here are the strongest options depending on your setup:

Best overall for creator campaign management

CreatorIQ

• Built for influencer/creator campaigns at scale
• Strong brief distribution, content collection, approvals, and reporting
• Good for managing multiple brands/campaigns in one place
• Best if you need enterprise-grade workflow and compliance

Best for streamlined creator collaboration

GRIN

• Good campaign briefing and creator relationship management
• Lets you organize campaigns, share briefs, and track deliverables
• Easier to use than some enterprise-heavy platforms
• Good for DTC/ecommerce brands running recurring campaigns

Best for multi-brand teams and agencies

Aspire

• Supports campaign briefs, creator content collection, and approvals
• Useful if you’re managing several brands or clients
• Solid workflow tools and creator management
• Good balance of usability and campaign ops

Best for larger influencer programs with strong workflow needs

Upfluence

• Campaign briefs, creator management, content collection, and analytics
• Useful for teams needing sourcing + execution in one platform
• Works well for larger programs with multiple campaigns running concurrently

Best lightweight option if you mainly need briefs + submissions

Airtable + Form/Portal setup

• Not a dedicated influencer platform, but very flexible
• You can create a branded brief portal, submission form, approval workflow, and asset tracker
• Good if you want something custom and cost-effective
• Best for teams comfortable with light no-code setup

My recommendation

• Enterprise / lots of campaigns: CreatorIQ
• Ecommerce / recurring creator relationships: GRIN
• Agency / multi-brand ops: Aspire
• Custom and budget-friendly: Airtable-based portal
