What started as a tool for law firms is now shipping to everyone on Mantle.
Most founders don’t think about equity workflows until they’re buried in them.
You’re trying to clean up your cap table. You’ve got a folder of SAFEs, share class documents, grant agreements. You’re flipping between PDFs and a spreadsheet (or a half-configured platform) and trying to make sure every term is entered exactly right — valuation caps, discounts, vesting schedules, classes of shares.
It’s slow. It’s fragile. It’s the kind of thing you dread doing, but can’t afford to mess up.
So we built AI Extract to take that pain away.
Upload your documents — SAFEs, founder share agreements, your charters, equity plans, convertible notes, share classes, equity grants — and Mantle will pull out the key terms using AI and fill in your equity records automatically.
You just review and approve.
No more copy-pasting. No more errors.
Just fast, accurate equity records — created in seconds.
It Started with a Tool for Law Firms
AI Extract wasn’t originally built for founders.
It started as a side tool we were building for law firms — something to help them tie out cap tables faster by extracting key terms directly from legal docs. No data entry. No flipping between SAFEs and spreadsheets.
When we showed it to law firms, their jaws hit the floor.
They’d never seen AI applied this cleanly to legal workflows. No tagging. No highlighting. Just upload the doc → get structured data → confirm.
That’s when it clicked. If the professionals doing this all day were blown away, how much pain were founders and operators dealing with — trying to piece together the same data with way fewer tools and less legal support?
So we expanded it.
We took the same tech, cleaned up the interface, and built it directly into Mantle. Now, every company, not just law firms, can use AI Extract to draft accurate equity records in seconds.
How AI Extract Works (For the Curious)
Under the hood, AI Extract is powered by a custom-built pipeline that uses large language models to understand legal documents — and translate them into structured data for your cap table.
Here’s what’s happening when you upload a doc:
- Document classification
We detect what type of legal instrument it is (SAFE, grant, share class, etc.) - Term extraction
We use prompt-chained LLMs — tuned to legal-financial context — to extract the specific fields relevant to that document type (e.g. valuation cap, discount, share class name, vesting terms). - Auto-fill + human review
The extracted data is mapped to Mantle’s equity model and pre-filled into the relevant record. You can review, edit, and approve before anything is finalized.
No training. No field mapping. No complicated setup.
Just drop the doc in and let the system do the heavy lifting.
Why This Changes the Game
Equity is the backbone of your company, but the workflows around it are broken.
Founders waste hours parsing legal docs, chasing down attorneys, and maintaining spreadsheets that don’t reflect reality. And even when they graduate to a cap table platform, they often end up doing the same manual work, just in a different UI.
AI Extract flips that dynamic.
It gives founders a smarter starting point — one where your legal inputs automatically become structured, compliant records you can actually work with.
It’s faster. It’s safer. And it’s the kind of tool that makes you wonder why you ever did this manually in the first place.
Stay tuned as we roll out more ways to use our data extraction engine.
