About
What OpenShut is.
OpenShut is a deterministic closing-document platform for US business transactions. A lender, sponsor, founder, or their counsel enters the deal terms, and the platform returns the complete, signature-ready binder the transaction requires. Every figure is computed in code from the terms and the governing program rules, and every clause is the operative text of the statute, regulation, or standard form it comes from. No language model drafts the legal text, so the assurance you rely on is the law itself.
Why it holds
You are not trusting a vendor. You are trusting the law.
A closing binder fails in three ways: a figure is wrong, a clause is misquoted, or the documents contradict one another when a counterparty reads them in diligence. OpenShut closes each of those at the architecture. The arithmetic is performed in code and reconciled to the term it came from. The operative language is reproduced word for word from the authority it cites, so counsel can open the source and confirm the clause is the one that controls. The same transaction produces the same binder on every run, version-pinned and available for review.

Frequently asked
Questions a first-time reader asks
- What is OpenShut?
- OpenShut is a deterministic closing-document platform for US business transactions. A lender, sponsor, founder, or their counsel enters the deal terms, and OpenShut returns the complete, signature-ready binder the transaction requires. Every figure is computed in code from the terms and the governing program rules, and every clause is the operative text of the statute, regulation, or standard form it comes from.
- Does a language model write the documents?
- No language model reads your data, drafts your documents, or decides your terms. The legal text is reproduced word for word from cited authority and source-verified forms, and the figures are calculated in code. Because nothing in the path is generated, there is nothing for a model to fabricate.
- How is OpenShut different from an AI legal tool?
- Most legal-AI tools rely on a language model to produce or rewrite the operative text and place the burden of verification on the user. OpenShut removes the drafting model. Each clause is fixed to its source and each figure is computed, so any provision in the binder traces back to the authority behind it rather than to a model's judgment.
- What deal types does OpenShut cover today?
- Live coverage spans SBA 7(a), 504, Express, and CAPLines lending; Common Paper B2B contracts, including NDAs, MSAs, SOWs, SLAs, SaaS agreements, DPAs, and vendor supply contracts; the YC SAFE family, pro-rata side letters, and the Series Seed equity and notes rounds; and the Section 83(b) election. M&A and real estate syndication are in development.
- How does OpenShut reduce my exposure on a closing?
- A closing binder fails when a figure is wrong, a clause is misquoted, or documents contradict one another in diligence. Because every figure is computed and every clause is fixed to its source, those failure modes are closed at the architecture. When an examiner, a credit officer, or counsel opens any provision, it reconciles to the rule that produced it and the term it was drawn from.
- Is OpenShut a law firm, and is this legal advice?
- OpenShut is not a law firm and does not provide legal advice. The platform assembles documents from your inputs and cited US law, and counsel review is recommended before execution.
- How is my data handled?
- Your data is encrypted in transit and at rest, isolated to your organization and reachable only by the members you authorize, and never used to train any model. Every action on a deal is written to a tamper-evident audit trail. The full security and compliance detail is documented for your team to review.
- Who uses OpenShut?
- Commercial lenders and credit officers, independent sponsors and search funds, founders and their counsel, family offices, and fractional general counsel — anyone who needs a closing binder that is both correct and reproducible.
- Can OpenShut be used through an API or by an AI agent?
- Yes. Deals can be created and documents generated through a REST API built to be called by your own systems or an autonomous agent, under the same governing rules that stand behind the interface.
- What does it cost?
- The first sample deal is free, with no card required. After that, pricing is by the transaction you close — no seat licenses and no monthly minimum, with volume terms for firms closing at scale.
