Poststack is the social media operations platform built for Indian agencies, made by Poststack LLP in Mumbai. Each client gets a workspace for their calendar, approval flow and publishing queue, with feedback from every point of contact in one place. Clients approve or request changes through a magic link; the agency keeps control of finalization, scheduling and publishing.

A four-person shop might carry twenty client accounts. The founder sends feedback at 11pm. A calendar says the post is ready, but the latest change is still in a message. Indian agencies need a system built around that working day.
Poststack starts from how Indian agencies actually operate. Each client gets a dedicated workspace for their calendar, approval flow and publishing queue. The latest version and the feedback that shaped it stay with the work.
The company behind Poststack, founded by Sahil Shah.
Poststack holds recognition under Startup India.
Instagram, Facebook, LinkedIn, X, YouTube and Threads.
Two ways to collect feedback, with one clear division of responsibility.
Share a magic link so a client can review a post and approve or request changes without creating an account. The link gives focused post access, not access to the whole portal.
Professional and Agency include authenticated client portal access for the calendar, posts and feedback. A white-label portal on your agency domain is a paid add-on, quoted on request, with a customer DNS setup step.
Require client approval before scheduling or leave it as a status tag, configured per client or workspace. The operator always controls finalization, scheduling and publishing. Revision rounds and version control are live on all three plans.
The calendar keeps scheduled work, feedback and publishing status together for each client. This is the product surface an agency returns to during the working day.

Schedule and publish through official platform APIs, then review analytics for all six supported platforms. Analytics exports are manual today. Automated reporting is coming soon.
Import posts from a spreadsheet with Import Sheet and bring media in from Google Drive. AI assistance and Canva integration are coming soon.
Pay by UPI AutoPay or card through Razorpay. Prices exclude GST; GST invoices are issued automatically.

Seats, social accounts and client workspaces scale independently. A team of four managing twenty clients can choose its account and seat allowances, then add more at the published rates.
