Partnership Tiers
Working Together

I'm looking for a
few right partners.

Main Branch isn't selling ad space. I'm looking for partners who believe in what this newsletter is building — a trusted space for developers who want signal, not noise. If your product genuinely helps developers ship better code, let's talk.

Newsletter Mention

A natural mention woven into the issue — your product introduced in context, with a link, seen by every reader in a space they trust.

Featured Partner

Your own section with logo and messaging, placed above the fold. Room to tell your story in up to 100 words, with a clear call to action.

Editorial Spotlight

A full feature written in Main Branch's voice — an honest look at your product, what it does well, and why it matters. Amplified across LinkedIn, X, and YouTube.

Why this matters to me. I built Main Branch because developers deserve better than recycled changelogs and hype cycles. Every word earns its place — and that includes partnerships. I will only work with companies whose products I'd genuinely recommend to a friend. If that's you, I'd love to hear from you.
