# Startup Presentation: IgniSign - Sign for Real

Integrate legally binding electronic signatures as easily as Stripe. IgniSign’s zero-knowledge API keeps documents entirely on your frontend while delivering EU-certified signatures for mere cents.

## Summary

IgniSign emerged from a clear market gap: the lack of a developer-friendly, legally binding, and cost-effective electronic signature API. Existing solutions often force users to upload sensitive documents to third-party platforms—creating inherent security vulnerabilities—and frequently lack probative value under European law. To solve the historical tradeoff between API usability and legal compliance, IgniSign built a platform that provides fully integrated, certified signatures equivalent to a notarization, recognized directly on the European Commission trusted list.

Designed specifically for developers and integrators, the platform mirrors the integration simplicity of tools like Stripe or Twilio, typically requiring less than a week to implement into existing workflows. It supports signing a diverse array of digital assets—including PDFs, smart contracts, NFTs, and video files—by leveraging a comprehensive identification system that incorporates eID, open banking, and SSO. Furthermore, by engineering their own Public Key Infrastructure (PKI), IgniSign drastically reduces operational costs, offering qualified signatures for mere cents on a frictionless pay-as-you-go model.

A standout innovation is IgniSign's patented privacy architecture, which completely eliminates the need to upload documents to external servers. Instead, files remain entirely within the user's frontend environment while only cryptographic hashes are exchanged with the backend. This approach fundamentally guarantees document confidentiality and seamless zero-knowledge security without compromising the certified, legally binding nature of the signature.
