Athennian

What it is

Athennian is entity management for corporate groups that have outgrown the subsidiary spreadsheet. Every legal entity, its formation jurisdiction, its officers and directors, its registered addresses, its share and debt structure, its filing deadlines, and its minute book live in one record set, with structure charts generated from that data instead of redrawn by hand in PowerPoint. Adrian Camara co-founded it in Calgary in 2016. It runs on about 79 employees against $46.7M raised across six rounds, including a CAD $42M Series B led by Centana Growth Partners. Athennian says more than 500,000 entities sit on the platform across close to 150 countries, and names Hitachi, Dell, EQT, Dentons, Shopify, and Inter Pipeline as customers.

The buyer here is not an in-house lawyer shopping for matter management. It is the corporate secretary, paralegal manager, or legal ops lead who owns the annual-filing calendar for 80 subsidiaries and currently owns it across Excel, a shared drive, and a registered agent’s portal.

Athennian is the only entity-management specialist in the ooligo catalog, which makes it the default first call on this evaluation. That is a fact about the category’s shape, not a coronation — the alternatives below are real.

Why it shows up in legal ops stacks

• Structure charts come out of the data. Ownership, hierarchy, and director-and-officer relationships render from the entity records as they change. What most teams live with instead is a Visio or PowerPoint chart that was accurate the day someone last redrew it — and the chart is the first artifact M&A diligence asks for.
• The minute book becomes a folder you can hand over. Documents, template automation, and e-signature sit on the entity record, so producing a virtual minute book is a download rather than a three-week scavenger hunt. Capterra reviewers describe that exact motion: pull a folder, download everything, share it.
• Beneficial ownership is a tracked field, not a project. UBO tracking ships at the entry tier, and Athennian publishes a 2026 global UBO guide covering 50 jurisdictions. After the CTA in the US and the equivalent EU registers, this is the surface that turned entity data from hygiene into a filing obligation.
• Cap tables and debt sit beside the governance data. Equity classes, share transactions, and debt instruments live on the same record as the appointments and registrations, which is why a tax or treasury team can query the system instead of asking legal for a screenshot.
• 2026 shipped work is agentic entity operations. Athennian AI runs workflows that create registrations, update signatories, process approvals, and execute entity changes read from source documents, with continuous reconciliation back against those documents. Athennian for Private Markets launched on June 1, 2026, aimed at GPs whose entity data is split across fund admins, law firms, and their own systems.

Pricing reality

Athennian publishes one number and quotes the rest. Essentials is $25,000/year for 100 entities, and includes centralized entity records, custom reporting, structure charts, supported e-filings, and UBO tracking. Professional (200 entities) and Enterprise (300 entities) are contact-sales. Extra capacity is sold in 50-entity bundles.

Read the published price per entity: $250/entity/year at Essentials. Entity count, not headcount, is the meter — so model it against your entity register, not your legal team. A 40-entity group still pays the 100-entity floor, which puts the effective rate near $625/entity/year at that size.

AI is not in the base price. AI Core is a paid add-on, alongside Intelligence, Enterprise SSO, and Configurability, so the AI-governed framing on the marketing site is a line item on the order form. The Open Read API and a sandbox environment start at Enterprise, which decides whether entity data can reach a warehouse or a reporting layer at all.

For contrast on the incumbent side, Vendr’s marketplace data puts the median Diligent contract at $23,800/year and the top of its observed range at $45,792. Athennian’s published floor lands at parity with what mid-market buyers pay Diligent. The argument for Athennian is price transparency and product shape, not a discount.

Best for

Corporate secretaries, paralegal managers, and legal ops leads running 50-500 legal entities across multiple jurisdictions, where the failure mode that keeps you awake is a missed annual filing or a diligence request that takes three weeks to answer. It is the strongest pick when entity and governance data is the primary job rather than one module inside a matter-management or enterprise legal management purchase.

Under roughly 25 entities in one or two jurisdictions, the $25,000 floor does not pay back. A registered agent’s compliance calendar plus a maintained register does that job.

Alternatives and when to pick them

• Diligent Entities (formerly Blueprint OneWorld) — the volume incumbent in the segment, rated around 4.2 on G2. Pick it when board and governance workflows already run on Diligent, so entity data and board reporting come from one vendor and one contract.
• CSC Entity Management — the other enterprise incumbent, and the pick when you want the registered-agent service, the filing coverage, and the software from a single provider. Its G2 rating sits near 3.3, so buy it for the service footprint rather than the product.
• DiliTrust — the AI-native challenger growing fastest in this segment: €130M raised to fund double-digit topline growth, named in Gartner’s 2026 Legal Technology Market Map for legal entity management, and taken private by PACTA in a February 2025 buyout. Pick it when entities are one of four things you need in one platform, next to contracts, board, and matters.
• Filejet — pick it when the real problem is narrower than governance: annual reports and registered-agent renewals getting filed on time. It automates the filings for a fraction of a platform price and is not a minute book.
• Xakia — pick it when entity management is one module you need beside matters, intake, and outside counsel spend for a 2-20 lawyer team, with an entity count in the dozens.

If none of these fit, the honest interim is a registered agent handling filings, an entity register with a named owner and a review date on every row, and a calendar. Buy software at the point where one person can no longer reconcile the register.

Watch-outs

• Document automation stops short of conditional logic. Reviewers report they cannot build complex codes and logic into the templates, and that automation updates disrupt established processes. Guard: run your two hardest document types — the resolution with jurisdiction-dependent clauses and the multi-signatory consent — through a trial build before signing, and keep the Word fallback template maintained.
• Entity search is the top usability complaint. Reviewers describe entity searching as inefficient and note that searches do not persist after a backspace, which hurts most during bulk updates. Guard: test search against a copy of your real naming conventions — numbered holdcos, near-duplicate names, non-Latin characters — during evaluation, and confirm bulk editing is in the tier you are quoted, since it starts at Professional.
• The API is gated to the top tier. The Open Read API and the sandbox begin at Enterprise, so a warehouse sync or a downstream reporting build is unavailable on Essentials and Professional. Guard: if entity data has to reach Snowflake, a BI layer, or an AI workspace, price Enterprise from the first quote rather than planning an upgrade you have not budgeted.
• There is no MCP server. Athennian’s AI runs inside Athennian, so querying entity and D&O data from Claude or Copilot means building against the REST API — and only at Enterprise. Guard: treat AI-workspace access as connector work you own, and verify the API exposes appointments and ownership objects before you commit to it. Background: MCP server explained.
• AI is an add-on bolted to a record system that predates it. The AI-governed positioning dates to 2026; the core platform dates to 2016. Guard: get the AI Core price in the same order form as the base tier, and test extraction accuracy against your own charter documents and consents rather than a demo corpus.
• The 2023 layoffs and leadership turnover are on the record. BetaKit reported layoffs and leadership changes while the company worked through growing pains, with Camara describing the company as financially and operationally stable. Guard: on a multi-year commitment, get data-export terms in writing and confirm during the trial that you can extract minute books and the full entity register in a usable format on exit.
