First post from founder

👋 Hey Sumo-lings!

I'm Adrian, founder of QuickSigner -- a fast, secure, and affordable eSignature tool purpose-built for small and medium-sized businesses.

🛠️ Why we built QuickSigner

A few years ago, I was helping business partners in the UK digitize their document workflows. We explored all the major eSignature platforms, but quickly ran into a common issue: 💸 overpriced and overcomplicated.

We needed something straightforward, secure, and cost-effective — without sacrificing key features or getting locked into corporate pricing models.

So I teamed up with a group of talented developers and built QuickSigner. It started as an internal tool, but we soon realized it could help SMBs worldwide who face the same challenges.

🚀 What makes QuickSigner different?

QuickSigner offers the essential features you expect from top-tier eSignature platforms — minus the inflated pricing.

✅ Used across the U.S., Europe, and beyond 

✅ Upload, add recipients, and sign in just a few clicks 

✅ Legally binding, GDPR-compliant, and secure (ISO/IEC 27001:2022 certified) 

✅ Full audit trail with signer metadata and timestamps 

✅ Recipients can sign without creating an account 

✅ Fast, intuitive interface — no learning curve required

✅ Enhanced API for deeper app/workflow integration

Our users love that it just works — no unnecessary complexity or bloated interfaces.

🔮 What’s on the roadmap?

 We’re actively building features based on user feedback. Here’s what’s on the roadmap:

📦 Bulk signing
🤝 White labeling (perfect for agencies & resellers)
📲 Sign via SMS
🔌 Enhanced API for full integration into your apps & workflows

👉Check out the full roadmap here: https://www.quicksigner.com/roadmap

🌎 Who Is QuickSigner For?

QuickSigner is designed for for:

Small and Medium Businesses (SMBs)
Freelancers and Consultants
Agencies & SaaS Founders
Legal, HR, Real Estate, and Sales Teams
Anyone who sends contracts regularly

Currently, the platform interface is in English, with more languages coming soon.
