Everything in one place
Run every client's social media from one workspace
Stop stitching together native apps, spreadsheets and screenshots. Castessa is the single source of truth for your agency's social performance.
Unified FB + IG analytics
Facebook and Instagram in one view — views, reach, engagement, followers. Cross-posts are matched and merged so numbers aren't double-counted.
Organic vs Boosted
See paid reach and spend next to organic, with a Boosted badge and combined totals. Prove what the boost actually delivered.
Multi-client workspaces
Every client is isolated. Switch between them instantly, and keep data cleanly separated across your whole roster.
Publish & schedule
Compose once and publish to Facebook and Instagram together — no more juggling native apps for each client.
Automated client updates
A scheduled digest of the latest posts and results, delivered automatically — clients stay in the loop with zero effort.
Client-ready reports
Share a live dashboard or export a clean report. Invite client users as Reviewer or Manager with scoped access.
Prove what the ad spend actually did
Most tools blur organic and paid together. Castessa keeps them separate — organic reach, boosted reach, spend and results per post — then shows a combined total with a clear Boosted badge. Your clients finally understand the difference between reach they earned and reach they paid for.
- Organic, boosted and total — per post
- Spend and results pulled from the ad account
- A Boosted badge everywhere it matters
