About this launch
KeelStack is a sponsor CRM built for solo newsletter and podcast creators managing direct sponsorship deals. The platform provides a sponsor pipeline organized as a Kanban board, a magic-link portal where sponsors upload their own assets without creating an account, and automated renewal reminders at 30, 14, and 7 days before each renewal.
The tool handles invoice tracking with automatic KS-numbered records, generates one-page branded performance reports, and provides a revenue dashboard showing MRR, renewal rates, and quarterly trends. Unlike sponsor marketplaces, KeelStack charges a flat monthly subscription with 0% commission on sponsorship revenue.
KeelStack is platform-agnostic and works with Substack, Ghost, Kit (ConvertKit), Beehiiv, and any podcast host. Setup takes about 5 minutes, and users can import sponsors from spreadsheets. The product is built for creators running 3–15 direct sponsorship deals per quarter.

Shopper questions
What is KeelStack?
KeelStack is a sponsor CRM built for solo newsletter and podcast creators running 3–15 direct sponsorship deals. It combines a sponsor pipeline, a magic-link portal where sponsors upload their own assets, automated renewal reminders, invoice tracking, and one-page performance reports without spreadsheets, email threads, or a percentage of your revenue.
How is KeelStack different from a spreadsheet?
A spreadsheet doesn't send sponsors a magic link to upload assets, doesn't remind you about renewals at 30/14/7 days, doesn't track who owes you what, and doesn't produce a one-page performance report. KeelStack does all four in one place and remembers everything for you next quarter.
Do sponsors need to create an account?
No. Sponsors never create an account, remember a password, or log in. You send them a single magic link and they land on a portal page branded to your publication where they upload their logo, banner, sponsor copy, and tracking URL, and can watch their deal status update in real time.
What happens when my 14-day trial ends?
After 14 days, your workspace becomes read-only for a grace period so you can still export your sponsors, invoices, reports, and assets, or pick a plan to flip everything back on. Add a card to continue on Starter, Pro, or Business, or do nothing and your data is deleted or anonymized after the grace period.
Does KeelStack take a percentage of my sponsorship revenue?
No, never. KeelStack charges a flat monthly or annual subscription fee and takes 0% of your sponsorship revenue. Unlike sponsor marketplaces that take 5–15% per deal, what you earn from your sponsors stays entirely yours.
