Key Highlights
• Every inbound contract, from NDAs to customer and vendor agreements, moves through one continuous flow instead of four disconnected tools
• Lexi reviews each contract against the company’s playbook automatically and flags deviations before a lawyer opens it
• Redlines drafted automatically, and new agreements generated straight from templates rather than built from scratch each time
• Signed agreements routed for signature and filed automatically into a searchable repository, nothing left sitting in an inbox
• The team reviews and approves finished work instead of assembling contracts piece by piece across separate tools
About the company
Unsiloed AI (YC F25) builds production APIs that turn complex documents, PDFs, spreadsheets, presentations, into clean, structured data that AI systems can work with reliably, for finance, legal and healthcare workflows. Founded in 2024 and based in San Francisco, the company moves at the pace typical of an early venture-backed team: closing customers, vendors and partners quickly, without a large in-house legal department sized to match the volume.
That combination, high contract volume and a lean team, is exactly where a contract process built from separate, disconnected tools starts to show its cracks.
Opportunity
A fast-growing company signs a lot of paper. Customer agreements, data processing agreements, vendor contracts, NDAs, arriving continuously, each one needing to be checked against the company’s own playbook before anyone puts their name to it. Handled the old way, that meant four disconnected tools and a handoff between each one: a place to review, a separate place to draft redlines, another to generate a new agreement from a template, and yet another to chase a signature and file the result somewhere it could actually be found again. Every handoff was a place a contract could stall, or drop entirely.
For a small team without the luxury of a large legal department, that overhead was not a minor inefficiency. It was the ceiling on how fast the company could actually move.
“Contracts do not arrive on a schedule that suits a four-tool process. Every handoff between reviewing, drafting, generating and filing was a place something could sit for a day longer than it should, or get lost entirely.”
Aman Mishra, Co-Founder and CEO, Unsiloed AI
Solution
Lexi gave Unsiloed a single, continuous flow for every contract, from the moment it arrives to a signed, filed agreement, with a lawyer touching only the parts that need judgment.
One flow, not four tools
A contract arrives, and Lexi reviews it against the playbook, flags any deviations, drafts the redlines, and, for a new agreement, generates it straight from a template. The same document moves on to signature and filing without ever leaving the flow or changing hands between separate tools.
Review and approve, not assemble
The lawyer’s role shifts from constructing a contract by hand to reviewing what Lexi has already built. What reaches them is a decision to make on flagged deviations and redlines, not a document to build from a blank page and a playbook.
“What lands on my desk now is a contract that has already been checked against our playbook, with the deviations flagged and the redlines drafted. I am making a call, not building a document.” · Aman Mishra
Nothing lost after signature
Once an agreement is signed, it is filed automatically into a searchable repository, rather than sitting in an inbox or a folder waiting to be found again months later when it actually matters.
Impact
The change is not that Unsiloed’s team does less work. It is that the work they do is judgment, not assembly. A contract that used to touch four separate tools, and however many handoffs in between, now moves through one continuous flow, from arrival to signature to a searchable file, and a lawyer reviews and approves rather than builds from nothing.
For a company whose entire business is turning unstructured documents into something reliable, running its own contracts through a single structured flow instead of four disconnected tools is, fittingly, exactly the kind of problem Lexi was built to solve.
“Contracts move through one flow now: reviewed against our playbook, redlined, generated from a template if it is new, signed, and filed, without four tools and a set of handoffs in between. I approve the work. I do not assemble it anymore.”
