Why we built ArcaSign
In Costa Rica —and across much of LATAM— signing a contract still works the same way it did twenty years ago: print, sign by hand, scan, send over WhatsApp, wait, lose track. Documents circulate as low-quality scanned PDFs, wet signatures take days, and no one is sure which version is the final one.
ArcaSign was built to solve exactly that. It is a legally valid electronic signature platform designed for the Costa Rican market: with legal validity under Law 8454, documents stored in the cloud with encryption at rest, and a support team that speaks the same language and lives in the same time zone.
All within a single platform, with a signing history and verification from start to finish. No improvised flows over email or messaging apps.
The bigger goal
Document disorder is not only a business problem. It is a systemic one. Court files go missing. Contracts are disputed because there is no definitive version. Legal proceedings drag on for weeks over a signature no one can find. In many countries in the region, procedures that should take hours take months — and a significant share of that friction comes from poorly managed documents.
We believe that truly digitizing documents —not scanning PDFs, but signing and archiving with a verifiable history from the source— is one of the most direct levers for improving our countries’ legal and judicial systems. Not as a utopia, but as concrete infrastructure.
ArcaSign starts with businesses because that is where the greatest immediate traction lies. But the long-term goal is more ambitious: to help the countries of the region achieve modern, auditable and accessible document processes. A signature done right today is a case file that isn’t lost tomorrow.
