Instant, secure one-click signatures

Ravi Arul founded Centilio Sign to simplify and streamline document signing for businesses that struggle with tedious, error-prone paperwork. Frustrated by complex and costly e-signature tools, he built a no-frills platform that lets users upload documents, add drag-and-drop signature fields, and collect legally binding e-signatures in seconds—without requiring recipients to log in or download software.

With integrations for Google Drive, Dropbox, CRM apps, and a REST API, Centilio Sign fits seamlessly into existing workflows, automates reminders, and provides real-time tracking and audit trails. By focusing on simplicity, affordability, and bank-grade security, the tool aims to eliminate delays, reduce errors, and help small businesses and teams close deals faster.

Designed with teams in mind, it supports unlimited envelopes, templates, and users, with permission controls and activity monitoring from a central dashboard. Backed by AES-256 encryption and customizable security settings, Centilio Sign offers enterprise-level protection without complexity.
