Ordinal
Ordinal is an end-to-end social media management platform for teams: draft, plan, schedule and cross-post across ten channels, coordinate approvals and team engagements, and track daily analytics. Its deepest coverage is on LinkedIn.
What is Ordinal?
Ordinal is a social media management platform published by Assembly Labs Inc., a Delaware company based in San Francisco with a second office in Austin. It was called Assembly until November 2025; the new name comes from ordinal numbers — first, second, third — and states the product's thesis, that social content works when it follows an order rather than an impulse.
The platform gathers ten publishing destinations in one workspace: LinkedIn, Twitter/X, Instagram, Facebook, TikTok, YouTube Shorts, Threads, Webflow, Slack and Discord, with several accounts allowed per channel. Work is organised into workspaces, campaigns, a visual calendar, labels used as content buckets, statuses, ideas and drafts, and recurring posts.
LinkedIn is where Ordinal goes deepest. It tags both personal profiles and company pages, previews a post exactly as it will appear including the cut before the "see more" fold, supports native bold and italics, and accepts video, images and PDF carousels. Account and post analytics refresh daily for personal as well as company profiles, without a browser extension, and now include saves and sends.
Around publication sits a coordination layer. Approvals can be optional or blocking and reach reviewers through Slack or email. A Notion-like editor carries in-line comments, public share links and per-channel version history with word-level diffs and one-click restore. Team engagements let colleagues like, comment first or repost from their own LinkedIn and X accounts for up to twelve hours after publication, within per-plan caps, while a Slack Boost channel pings the team the moment a post goes live.
Higher tiers add an acquisition layer: amplification links, leads data, CRM connection, and employee or executive advocacy with post variants, advocate calendars, departments and locations.
Ordinal is also unusually open for its category. A REST API, an MCP server for AI tools, typed webhooks, CSV exports and a dedicated Agency API make the workspace programmable from the Pro plan upwards. AI assists rather than leads: drafting within a monthly quota, an AI Post Reviewer that flags typos, suspicious links, mismatched previews and untagged mentions, and AI Reporting still in beta. The company claims more than 1,000 marketing teams, and names Clay, Replo, Beehiiv and Pylon among its customers.

When to use Ordinal / When not to
A quick filter to help you decide if Ordinal is the right fit.
When to use Ordinal
- B2B and SaaS marketing teams that treat social as an acquisition channel rather than a broadcast feed

- Companies running executive or employee advocacy programmes, with amplification links and advocate calendars
- Organisations whose main channel is LinkedIn and who need personal-profile tagging and native analytics
- Growth and operations teams that want to drive the whole workspace from an API, an MCP server or webhooks
When not to use Ordinal
- Solo creators and side projects: there is no permanent free plan and the entry point is 95 USD per month
- Teams that need a mobile application, as no iOS or Android app is offered
- Paid social and advertising work, since the platform is entirely organic
- Organisations bound to European data residency, because everything is hosted and processed in the United States
- Non-English-speaking teams, as no interface language other than English is documented

- Sign up on the web application and start the 14-day trial, which requires no credit card
- Create a workspace, invite teammates and set their roles and permissions
- Connect your social profiles through OAuth, one or several accounts per channel
- Draft a post in the editor, attach images, video or a PDF carousel, and check the per-channel preview
- Send the post through approval, optional or blocking, and collect in-line comments

Data, GDPR & hosting
A consolidated view of how Ordinal handles your data.
GDPR overview
GDPR implementation is contractual and unusually detailed for an entirely American company. Ordinal publishes a Data Processing Addendum, version 1.2 updated on 14 July 2026, which incorporates the EU Standard Contractual Clauses of Decision 2021/914, the UK International Data Transfer Addendum and the Swiss FADP, makes the customer controller and Ordinal processor, and commits to audit cooperation under Article 28(3)(h). Section 12 of the privacy policy sets out the legal bases and the complete list of data-subject rights, together with the right to complain to a supervisory authority, and a public subprocessor list is maintained. Two gaps are explicit: no EU representative is designated under Article 27 and no data protection officer is named, so privacy requests go to the general support mailbox. All data is transferred to and processed in the United States.
Who owns the data?
Under section 6.1 of the Terms of Service, you keep every ownership right in the content you create, upload or publish, and Assembly Labs claims none of it. Section 6.2 grants Ordinal only a worldwide, non-exclusive, royalty-free licence to host, store, transmit, display and distribute that content for the sole purpose of operating the service; the licence ends when you delete the content or your account, except for material already shared with others or published to third-party platforms. The platform itself remains the property of Assembly Labs under section 8.1. In the Data Processing Addendum the customer is the controller and Ordinal the processor, and personal data is never sold.
Reuse rights
Yes. Because ownership stays with you, your content can be reused, republished, exported or repurposed freely, with no permission to ask from Assembly Labs. Ordinal's own use is bounded by what the service does: hosting, organising, scheduling, publishing, analysing, and — only at your instruction — generating or reviewing content with AI. Your content is transmitted to the social platforms you connect and handled by the named subprocessors, including OpenAI and Anthropic. Annex I of the Data Processing Addendum states that Ordinal does not use, and does not allow its AI subprocessors to use, customer personal data to train or improve general or shared AI models unless you expressly opt in in writing. Analytics can be exported as CSV or read through the REST API. One exception deserves attention: section 8.3 of the Terms gives Assembly Labs a perpetual, irrevocable, royalty-free licence over any feedback or suggestion you send.
Data retention & training
Hosting summary
Assembly Labs is established in the United States, and the privacy policy states that data is transferred to, stored and processed there; using the service from outside the country implies consent to that transfer. Every one of the sixteen providers on the published subprocessors page is located in the United States. Application hosting and content delivery run on Vercel, the managed database and authentication on Supabase, background jobs on Inngest, logging on Axiom, error monitoring on Sentry, notifications on Knock, real-time collaboration on Liveblocks and link analytics on Dub. AI content generation and review are handled by OpenAI and Anthropic. Outside customer-data processing, Stripe handles payments, Plain support, Loops lifecycle email, Google and PostHog analytics, and Unkey API keys. Annex II of the DPA describes encryption in transit over public networks and at rest at the managed database and storage layer, least-privilege access control, multi-factor authentication for privileged access, and logging and monitoring. No European data residency option is offered.
Things to keep in mind
Risks and trade-offs to weigh before adopting Ordinal.
- Automated team engagements sit close to the edge of what social platforms allow, and section 5.2 of the Terms makes you, not Ordinal, solely responsible for complying with each platform's rules
- Ordinal gives no guarantee of lasting compatibility with third-party APIs, which the platforms can change at any time
- Personal data leaves the European Union: processing happens in the United States, and using the service implies consent to that transfer
- No EU representative under Article 27 and no named data protection officer, so privacy requests land in a general support mailbox
- No published security certification, neither SOC 2 nor ISO 27001, so the technical measures rest on the vendor's own description
- Scheduling at volume can turn publishing into a habit that outruns editorial judgement: the AI reviewer catches typos, not a thin idea
- Content already published to a third-party platform stays there under that platform's retention rules, even after you delete it inside Ordinal
Setup & Integrations
Technical difficulty
Low for the everyday user: sign-up, workspace creation and OAuth connection of social profiles need no technical skill, and the quickstart guide promises a few minutes. The real effort is organisational — deciding permissions, approval rules, labels, campaigns and, for agencies, the workspace-per-client structure. An optional technical track exists for teams that want it: API keys, REST calls with a Bearer token, an MCP server, typed webhooks with custom headers, and SAML/SSO on Enterprise. API access requires at least the Pro plan, and onboarding support is included from the Growth plan.

Should you pick Ordinal?
Ordinal is a team tool, and its pricing says so plainly: with no permanent free plan and a 95 USD monthly entry point, it addresses marketing departments, agencies and founder-led companies rather than individual creators. Within that audience its case is strong. LinkedIn is where it clearly leads — personal-profile tagging, faithful previews, native formatting, PDF carousels and daily analytics for personal as well as company accounts, with no browser extension involved. Around that sits a coordination layer agencies in particular will recognise: separate workspaces, optional or blocking approvals, in-line comments, version history and Slack-routed notifications.
The second distinguishing trait is openness. A REST API, an MCP server, typed webhooks, CSV exports and an Agency API make the workspace programmable, which is rare in this category and genuinely useful to growth and operations teams who want social data sitting alongside the rest of their stack.
On data protection the contractual work is serious for a company of this size: a Data Processing Addendum incorporating the EU Standard Contractual Clauses, the UK Addendum and the Swiss FADP, a published subprocessor list, and a written commitment not to train AI models on customer personal data without an explicit opt-in. The limits are just as clear. Everything is hosted and processed in the United States, no EU representative is designated under Article 27, no data protection officer is named, and no security certification is published.
Three commercial points deserve attention before signing: fees are non-refundable in every circumstance, subscriptions renew automatically, and the acquisition features that justify the product's revenue framing only appear on the 695 USD Growth plan. Teams whose social effort genuinely feeds a pipeline will find that defensible; those who simply want to schedule posts will find cheaper answers elsewhere.
