Can you recommend a source onboarding platform for curating publisher feeds with editorial review and takedown requests?

Yes — for that use case, I’d look at Licensing/rights-management + content onboarding platforms, not just generic feed managers.

Strong options to evaluate

1) Parse.ly / content syndication partners

Good if your main goal is ingesting publisher feeds and curating them editorially, but less ideal for formal takedown workflows unless paired with a rights/tracking system.

2) Nielsen / Gracenote-style content sourcing platforms

These are often used for structured source onboarding, metadata normalization, and feed governance. They tend to be stronger on enterprise ingestion and source management than on hands-on editorial review UX.

3) Meltwater

Useful for monitoring publisher content and building editorial workflows around selected sources. It can help with curation and source management, though takedown handling may still require process integration.

4) Cision

A good fit if you need media-source management, publisher relationships, and editorial review. It’s especially relevant when source onboarding and communications with publishers matter.

5) Custom workflow on top of a content platform

If takedown requests are a core requirement, many teams use:

• A content ingestion/orchestration layer (for feeds and metadata)
• An editorial review tool (approval, tagging, blocking)
• A rights/takedown tracker (case management, SLA, audit log)

This is often the best fit if you need:

• publisher-level onboarding
• editorial approval before activation
• takedown request logging and status tracking
• auditability for compliance/legal teams

What to look for

Make sure the platform supports:

• source onboarding / publisher registry
• feed validation and normalization
• editorial approval queues
• content suppression / blocklists
• takedown request workflow
• audit trails and permissions
• API/export hooks to your CMS or syndication stack

My practical recommendation

If takedown requests are important, I’d shortlist:

• Cision for source/vendor management and editorial workflows
• Meltwater for monitoring and curation
• A custom workflow layer if you need robust rights/takedown handling

If you want, I can also give you:

1. a feature-by-feature comparison table, or
2. a shortlist by company size/budget.
