15-seat team sponsor CRM

Built for sponsor agencies managing dozens of deals across multiple team members. $79/mo (Growth) or $109/mo (Scale) with 15 seats, 10 publications, native ESP integrations (beehiiv, Mailchimp, Kit, Campaign Monitor, Ghost, Sailthru, Omeda), automated performance reporting, and a branded sponsor portal with login.

Where it falls short: Wrong ICP — a solo creator pays for 15 seats and 10 publications they will never fill. The team-collaboration features are dead weight at solo scale.

Sponsor marketplace + CRM

A discovery marketplace where creators list their inventory and sponsors browse. The CRM layer is bolted on; the marketplace is the product. Passionfroot takes a 5% commission on self-sourced deals and 15% on network-sourced partnerships. KeelStack charges a flat monthly subscription with 0% commission on sponsorships — ever. Includes Zest AI agent for campaign planning, Stripe-powered payments, and storefront-based creator discovery.

Where it falls short: Passionfroot takes a 5–15% commission on every deal — the better you do, the more they take. KeelStack charges a flat subscription with 0% commission. No native CRM integration (HubSpot/Salesforce), no ESP integrations, and the 15% network fee becomes expensive at scale.

Free sponsor booking + checkout

A free self-serve booking platform with Stripe checkout, automated asset collection with deadline reminders, capacity enforcement, and 7-day payout buffers. Verified audience data from Beehiiv and Kit via API. No pipeline, no renewal automation, no invoicing, no reports.

Where it falls short: Free because it doesn't remember anything about your sponsors — no memory of past deals, no renewal automation, no pipeline. You outgrow it the day you have 3+ sponsors.

Deal-pipeline CRM for landing sponsors

A Kanban deal pipeline (Inquiry → Negotiating → Contract → Invoiced → Paid) with a rate-card PDF generator, e-signature contract templates, and Stripe invoicing. Starter $29/mo (10 active deals), Pro $59/mo (unlimited deals + analytics), Agency $149/mo. Built for the sales side of sponsorships: getting a deal signed and paid.

Where it falls short: Stops at "paid." No sponsor-facing portal for asset delivery, no renewal reminders, and no post-campaign performance report — the exact three things that determine whether a sponsor books again. It solves the deal you are closing, not the one you are trying to keep.
