Document signing, reimagined
BuiltSign was founded with a simple belief: signing documents shouldn't be complicated. We're building the most intuitive, secure, and powerful document signing platform for modern businesses.
Our Story
BuiltSign started in 2026 when we experienced firsthand the frustration of signing large business documents. Existing solutions were slow, clunky, and couldn't handle files larger than a few megabytes.
We set out to build something better. A platform that could handle 800-page contracts as easily as a single-page NDA. One that was fast, secure, and a pleasure to use.
Today, BuiltSign is ready to power document workflows for businesses of all sizes — from solo entrepreneurs to growing teams. And we're just getting started.
Our Mission
We believe that business agreements shouldn't be slowed down by outdated technology. Our mission is to eliminate the friction in document signing, making it faster, more secure, and more accessible for everyone.
Whether you're a freelancer sending your first contract or an enterprise managing thousands of agreements, BuiltSign provides the tools you need to move fast and stay compliant.
BuiltSign is a registered trade name of Crul.Dev, registered at the Dutch Chamber of Commerce (KVK 97533114). We build software that meets the highest standards of privacy and security expected by European businesses and beyond.
