Works until you have 5 sponsors, then collapses into a tangled web of tabs. No portal, no sponsor-side upload, no audit trail.
What people switch to instead
Four realistic options for a solo creator running direct sponsorships.
KeelStack
RecommendedThe sponsor operations layer for solo creators running 3–15 direct deals. A magic-link portal where sponsors upload their own assets, automated 30/14/7 renewal reminders, invoice tracking, and branded one-page reports — across any platform, with no percentage of your revenue.
- Flat $39/mo — no seat minimums
- 0% of your sponsorship revenue
- Platform-agnostic (any ESP or host)
- Sponsors never create an account
Sponsy
from $79/mo15-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.
Compare with KeelStackPassionfroot
from Free + 5–15% of revenueSponsor marketplace + CRM
A discovery marketplace where creators list their inventory and sponsors browse. The CRM layer is bolted on; the marketplace is the product. Free core product with transaction-fee pricing: 5% on self-sourced deals, 15% on network-sourced partnerships. Includes Zest AI agent for campaign planning, Stripe-powered payments, and storefront-based creator discovery.
Where it falls short: Takes 5–15% of every deal — the better you do, the more they take. No native CRM integration (HubSpot/Salesforce), no ESP integrations, and the 15% network fee becomes expensive at scale.
Compare with KeelStackSponsorCal
from FreeFree 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.
