The most requested feature from Mantle founders is here
One request has come up again and again in our conversations with founders: let us use our cap table in Claude.
It makes sense. You’re already using Claude to write the board update, prep for the investor call, and draft the offer letter. Every one of those needs a number from your cap table, and until now getting it meant leaving Claude, logging into Mantle, and copying it over by hand.
As of today, Mantle Equity connects directly to Claude via MCP connector. Ask about ownership, your option pool, or your SAFEs, and Claude answers with live numbers from your Mantle account, right in the conversation you’re already having.
Where it helps most
Board meeting prep
“Pull our current fully diluted ownership and list every option grant we’ve made since the last board meeting.”
The equity section of a board deck used to take an afternoon of pulling numbers. Now Claude gathers them in seconds, and you get that time back for the parts of the meeting that actually need you.
Making an offer
“How much of the option pool is still available, and how many grants could we make at 0.5% each?”
Know whether you have room for that senior hire before the offer goes out, and spot early when it’s time to ask your board to top up the pool.
Answering investors on the spot
“Who are my top 10 shareholders on a fully diluted basis?”
Investors ask about ownership on almost every call. Now you can answer during the call instead of promising to follow up afterward.
Staying on top of SAFEs
“How much have we raised on SAFEs in total, and which are post-money vs. pre-money?”
Claude lays out every SAFE with its amount, valuation cap, and discount, so you know exactly where you stand when you start planning your priced round.
Getting ahead of diligence
“Check that every security on our cap table has a supporting document, and list the gaps.”
Run this in Claude weeks before diligence starts. Claude checks each security in Mantle against your data room and hands back a list of what’s missing, so you can fix it before your lawyers or investors find it.
What Claude can see
Once connected, Claude can read:
- Your cap table and stakeholders
- Shares, options, SAFEs, convertible notes, and warrants
- Your option pool and the grants made from it
- Vesting schedules, board agreements, and much more
Claude checks Mantle every time you ask, so answers always reflect your cap table as it stands right now. Each person signs in with their own Mantle account and only sees what they already have access to in Mantle.
The connector is read-only. Issuing grants, updating securities, and signing documents still happen in Mantle, where your records stay clean and auditable.
