Cap tables look simple on paper. Equity divided, ownership percentages, done. But anyone who’s actually worked with them knows the reality: a stack of legal documents, PDFs scattered across emails and Drive folders, and what feels like a secret recipe for how they all add up to match the final numbers in your spreadsheet.
That knowledge lives in a few heads: a partner at the law firm, a friendly VC, your fractional CFO. It’s not documented. It’s just known. And when those people aren’t available, cap table management becomes a game of guess-and-check with real stakes.
We built Mantle by living in that reality. Every edge case, every round, every scenario that didn’t come with instructions.
We’ve internalized that recipe and given it a home in Mantle Clerk, the AI assistant built into our cap table software.
What is AI cap table software?
AI cap table software combines equity management (share classes, option grants, round modeling) with an AI layer that can read legal documents, identify what needs to happen, and execute — or draft — the right actions. Unlike traditional cap table tools that require manual data entry, AI cap table software understands context: the type of document, where you are in the company’s lifecycle, and what comes next.
What Mantle Clerk does
Most AI tools search your documents and return what they found. Mantle Clerk is different: it’s the accumulated knowledge of hundreds of cap table edge cases, encoded into a collaborator that knows how equity events actually behave.
For founders & operators
Setting up your cap table from scratch. Mantle Clerk starts with your Certificate of Incorporation and walks you forward through founder shares, equity plans, and option grants — in the right order, at each step.
“I want to get my cap table set up – where do we begin?”
“Welcome to Mantle. Cap tables are built off equity-related paperwork your company executes, and it’s easiest to start from the beginning. This typically starts with your Certificate of Incorporation, then founder shares, equity plans, and option grants. Do you have your Certificate of Incorporation handy?”
Onboarding a new hire. Drop in the offer letter. Mantle Clerk reads it, identifies the grant, and drafts everything needed for the next board action.
“I just hired someone. Here’s their offer letter.”
“Congrats on the new hire! John Doe is set to receive 10,000 options. Want me to draft the grant and attach it to your next board action?”
Closing a round. Hours of document review and manual entry, done in a conversation.
“We just closed our seed. Here’s the signed SPA and closing binder.”
“Nice work! I’ve found your updated charters with 2 new share classes, 7 new shareholders, 6 SAFE conversions, and an update to your equity plan. Let’s start with the share classes and work our way down.”
Staying ahead of your equity plan. Mantle Clerk monitors who’s approaching the end of their cliff or vest schedule so you can act before they do.
“Anyone I should be thinking of offering option top-ups to?”
”The following users are approaching the end of their vesting in the next 12 months. Let me know if you’d like to prep top-ups for any of them and I can get things started.”
For paralegals
Processing a board resolution. One document in. Everything that needs to happen on the other side of it, handled.
“Here’s the latest board resolution for Acme Inc.”
”I see the company has approved a new 409A valuation of $0.32, and 14 grants were approved as well. Would you like me to add the new valuation and draft the 14 grants?
Running a tie-out. Mantle Clerk walks through the data room methodically — charters first, then share issuances — the way an experienced paralegal would.
“I need to run a tie-out on a company. I’ve uploaded the files to the data room.”
”Let’s start with charters and equity plans to get the high-level figures in place before moving on to share issuances. I see 3 charter files in the data room spanning 2022 through 2025. Ready to begin?
Closing package review. The gaps that are easy to miss and expensive to explain, caught before they leave your desk.
“I need a closing package sanity check before we send to opposing counsel.”
”Most of the cap table is fully tied-out. There are a handful of grants supported by a board approval but lacking grant notices. OP-35 and OP-122 through OP-130.”
What makes Mantle different from other cap table software
Most cap table tools are data stores. You enter data, they display it. Mantle Clerk is the first AI cap table software built around the process of equity administration — the sequencing, the document reading, the edge cases — not just the ledger at the end.
It is not legal advice. Mantle Clerk encodes operational expertise: the mechanics, the timing, the “what happens if” reasoning that lives between formal legal questions. Legal questions still go to counsel. Everything in between comes here.
