Clerk | AI Assistant for Cap Tables

About Clerk | AI Assistant for Cap Tables

Clerk is an AI assistant built into Mantle, a cap table management platform. It answers plain-English questions about equity, models funding rounds, and drafts next steps based on uploaded documents or descriptions of closed transactions. The tool records changes to the cap table and links its answers back to the underlying data so users can verify the source.

Review

Clerk takes aim at a familiar founder headache: cap table questions that typically require a lawyer, a paralegal, or a VC's mental model to answer. Instead of digging through email threads or spreadsheet tabs, users can ask a question, drop in a document, or describe a recent close. Clerk responds with answers, records the event, and prepares the paperwork that follows. It sits inside Mantle's broader platform, which means the AI has direct access to the company's cap table data.

Key Features

• Natural language Q&A over cap table data. Users ask questions in plain English and Clerk pulls answers from the cap table, including links to the relevant sections in Mantle for manual verification.
• Document-based data extraction. Upload a legal document or agreement and Clerk extracts the relevant terms, records them, and reflects the changes in the cap table.
• Funding round modeling. Clerk generates pro forma cap tables for upcoming rounds. The output is intended for review by legal counsel before anything becomes official.
• Amendment and version history. Entries made by Clerk - or manually - can be amended later. Mantle treats the cap table as a record of what was filed and agreed upon, not an immutable ledger.
• Conversational transaction recording. Describe a grant or a round that just closed, and Clerk drafts the corresponding entries without requiring manual data entry into forms.

Pricing and Value

Clerk launched as a free addition to the Mantle platform. Mantle itself has a free Starter tier with unlimited stakeholders and core cap table features. Pricing for Mantle beyond the Starter tier is described as transparent and scales with company growth, though specific figures for paid plans are not publicly detailed in the launch materials. Whether Clerk will remain free across all Mantle plans or eventually sit behind a paid tier has not been stated.

Pros

• Answers link back to the cap table data in Mantle, so users can click through and confirm the source rather than trusting a black-box response.
• Records and drafts based on plain-English descriptions, cutting down the manual steps between closing a round and updating the books.
• Changes are amendable - the platform treats paperwork as the source of truth, not the software entry, which aligns with how corporate records actually work.
• Built directly into the cap table platform, so the AI works with live data rather than a static export or snapshot.
• Free at launch with no indicated paywall for the AI features at this stage.

Cons

• Clerk is tied to Mantle's platform - it doesn't function as a standalone assistant for companies using other cap table software or spreadsheets.
• The depth of its modeling capabilities for complex SAFE conversions - post-money vs. pre-money caps, discount stacking, option pool shuffling - hasn't been demonstrated publicly, and founders are advised to have lawyers review all pro forma outputs.
• Trust in AI-generated cap table entries remains an open question. While answers include source links and amendments are possible, catching a misread document before it affects downstream decisions still requires manual oversight.

Clerk fits early-stage teams already using or willing to adopt Mantle as their cap table platform, particularly founders who want to self-serve equity questions without waiting on counsel for every lookup. It's less relevant for companies with complex multi-entity structures that rely on dedicated legal ops workflows outside of Mantle's ecosystem. For the solo founder or small team moving fast through SAFEs and early grants, the combination of Q&A, document ingestion, and round modeling in a single interface addresses a real workflow gap.
