Clerk | AI Assistant for Cap Tables
Launching today
Everything you need to know about your cap table lives somewhere: in your lawyer's head, in a paralegal's inbox, in a VC's mental model built over decades. Mantle Clerk puts that knowledge in your corner. Ask a question, drop in a document, describe what just closed, and Mantle Clerk answers, records, and drafts what comes next.

Cap table questions are exactly the kind of thing founders need answered quickly, but really do not want answered incorrectly :)
As someone building a company with co-founders, the idea of asking plain-English questions, uploading documents, and having Clerk model a round or draft the next steps feels genuinely useful. The important part will be trust: does every answer show which documents, assumptions, and legal rules it relied on, and can founders require approval before anything is actually recorded or issued?

@andrasczeizelI love the idea of collaboration rules - adding that to our next roadmap discussion. At its core, Clerk is here to keep your cap table compliant. There will always be a role for lawyers on corporate records and governance; we just want them focused on the high‑value work they’re called in for, not dragged into cap table cleanup.
the trust question others raised is the right one for the Q&A side, but the part that would matter more to me is the write side. the description says Clerk 'records' things once you describe what closed, not just answers questions, so what's the safety net on the actual cap table data itself: if it records a grant or a round based on a misread document, is that a reversible, versioned change with a diff you can catch and undo, or does it write straight into the source of truth the same way a person fat-fingering a spreadsheet cell would

@galdayan at Mantle we treat the cap table as a distillation of the actual filings and agreements over time - and that distillation can include mistakes that deserve to be fixed. Whether Clerk pulled something from an uploaded document, a description of what closed, or someone skipped Clerk altogether and typed it in manually, those entries can be amended. The source of truth is what the paperwork says happened, not whatever happened to get recorded in software on a given day.
Suppose I ask this tool a question regarding my cap table, and it provides me with an answer. In such a case, how can I be sure whether this information is correct or not? Does this tool provide me with evidence from where it has taken this answer or not?

@saksham_salvi we built Clerk to help users get the answers they need and see exactly where those answers come from. When Clerk responds, it biases toward including links to the relevant areas of your cap table in Mantle, so you can click through, review the underlying data, and confirm everything directly in the platform.
the cap table space has a real trust problem already (409A valuations, option pool math, everyone's spreadsheet disagreeing with everyone else's) so I get why "just ask it" is appealing. more curious about the boring failure mode than the AI one though - who's actually liable if Clerk's model of a funding round is wrong and a company issues grants based on it? is there some kind of audit trail or sign-off step before anything becomes official, or does the AI output basically become the record?
the white-glove setup is such a smart move for founders who barely have time to eat, let alone migrate cap tables. love that it's actually built for day-one companies rather than scaling for an IPO you might never see.
The free tier with unlimited stakeholders is honestly such a rare move, and the fact that it actually feels polished instead of stripped down makes a huge difference. Really solid execution for founders who don't want to wrestle with spreadsheet formulas at midnight.
