About XOsign
Nobody should sign what they can't read.
XOsign is a universal agreement platform — create, understand, translate, refine, and sign. It started on a construction site, because that's where our founder ran into the problem first, and it turned out to be everyone's problem.
How we got here
Laurent Minguez is the founder of Xact Construction, a South Florida builder doing luxury residential and commercial work, and Heavenly Pros, LLC — a holding company across 14 portfolio operating companies running more than $200M in active development.
He signs subcontractor agreements every week. Most of those subs are Spanish-speaking. None of the tools he was using — Procore, Buildertrend, DocuSign — let his crews sign contracts they could actually read. The workarounds (Google Translate, pulling a bilingual foreman off the roof to translate at the truck) ranged from inconvenient to legally fragile.
XOsign exists because no existing software handled this. The first version was for his own crews. Then the same problem turned up everywhere else we looked — leases, service agreements, offer letters, loan paperwork, terms someone signs because they're expected to, not because they've understood them. Construction is still our deepest vertical. It is no longer the whole story.
“In the absence of fraud, the fact that an offeree cannot read, write, speak, or understand the English language is immaterial to whether an English-language agreement the offeree executes is enforceable.”
— Morales v. Sun Constructors, Inc., 541 F.3d 218 (3rd Cir. 2008)
That case is why XOsign exists. A federal court enforced an English arbitration clause against a Spanish-only welder because there was no record he understood what he signed. The signer happened to be a welder, but the holding is about English-language agreements generally — it reaches anyone who signs in a language they don't read well, and everyone on the other side of that signature. Signing in both languages closes the “in the absence of fraud” question before it ever opens.
What we're here to do
Mission
To make agreements easier to create, understand, translate, and sign — giving everyone greater clarity about what they're agreeing to.
Vision
A world where everyone understands what they're signing.
Brand promise
Understand before you sign.
What we value
Clarity First
Every feature answers one question: does the person signing understand more than they did before? If it doesn't, it doesn't ship.
Access for Everyone
Sending, signing, and storing agreements is free, in whatever language you read best. Understanding shouldn't be a paywalled privilege of the party with counsel.
Trust by Design
Tamper-evident audit trails and a clear record of what each party saw, in what language, and when. The receipts exist before anyone needs them.
Intelligence with Purpose
AI earns its place when it removes real work — reading, typing, translating, comparing. Never when it just looks impressive.
Both Sides Matter
An agreement only works when both parties understand it. We build for the person signing and the person sending, not just whoever bought the software.
How we build
Built for the people who sign, not the C-suite
Most agreements are drafted by one side, for one side. We build for the person on the other end of the signature. Construction is where we proved it — AIA G702 / G703 pay apps, Florida §713 lien disclosures, change orders, certificate-of-insurance requests and OSHA acknowledgments are all first-class, baked in rather than bolted on — and that's the depth we bring to every document type we take on.
AI does the typing
Take a photo of what you already wrote. We pull out parties, scope, pricing, and schedule, and rebuild it as a clean document — with the terms worth a second look brought to your attention. You stay in charge of every word; the AI just stops you from forgetting things.
Your language is a first-class language
Language isn't a formatting preference — it's whether consent is real. XOsign renders the document — and the plain-language explanation that goes with it — in the language each person reads most comfortably, and the audit trail records what each party saw, in what language, when. We started with Spanish because that's who our founder's crews were. The principle isn't specific to Spanish, or to construction.
Information, not enforcement
XOsign helps you understand the agreement. XOsign does not make the decision for you. We surface what the law typically requires and point out terms worth attention — we never tell you what to do. Big decisions stay with you, and we always recommend an attorney for those.
Why this matters
An agreement you can't read is an agreement you haven't really agreed to.
This isn't a niche problem — it's just most visible where the language gap is widest. 34% of US construction workers are Hispanic. Drywall installers: 75%. Painters: 53%. Construction laborers: 47%. In Texas, California, and Arizona, Hispanics are 61%, 55%, and 49% of the construction workforce respectively. The same question follows every lease, offer letter, and service contract signed across a language gap: does the person signing know what it says?
