What is Sinosend?
Sinosend is a B2B file transfer and document management platform designed specifically for international business operations. Sending large files across borders shouldn't feel like a gamble. We built Sinosend because the "big" file transfer tools weren't built for the complexities of global commerce. They lacked professional branding, ignored local data regulations, and struggled with cross-border speeds—especially to regions like China, India, and the Middle East.
Based in Hong Kong and serving businesses worldwide, we've built a high-speed, secure, and fully customizable bridge between you and your clients—no matter where they are. From fashion brands sourcing in Asia to accounting firms managing client documents, Sinosend handles the file transfers that drive international business.
The Problem We Solve
Traditional file transfer services like WeTransfer, Dropbox, and email attachments fail international businesses in three critical ways:
❌ No Brand Control
Generic links with third-party branding damage your professional image and reduce client trust.
❌ Compliance Nightmares
No control over data residency means GDPR, data sovereignty, and regional compliance violations.
❌ Cross-Border Failures
Files to China get blocked by the Great Firewall. Transfers to India and Middle East face high latency.
Beyond the Download Link: The Sinosend Difference
Most platforms give you a generic link and a "good luck" message. We give you a Digital Sales Room—a professional, branded experience that reflects your business standards while meeting global compliance requirements.
Industry-First Data Residency Control
Per-transfer data residency selection is our unique differentiator. Choose storage region (EU, US, APAC, UAE/Middle East) for each specific transfer—not locked into one data center for your entire account. Whether your client is in London, Dubai, Hong Kong, or New York, you control where data lives. Local speed, global compliance, zero enterprise gatekeeping. This solves GDPR Article 44, China's Personal Information Protection Law (PIPL), and GCC data sovereignty requirements.
White-Label Everything: Your Brand, Your Rules
Stop sending clients to someone else's website. With Custom CSS, white-label subdomains (docs.yourcompany.com), and custom email delivery, your file transfers look and feel like your own product. Every download page, upload portal, and email notification reflects your brand identity. Remove all Sinosend branding—we're invisible to your clients. This matters for agencies, professional services firms, and enterprise sales teams.
Built for Power Users and Enterprise Scale
100GB+ folder support with drag-and-drop, multi-language portals (English/Chinese auto-detection), resumable downloads for unstable connections, and tag-based organization (not folder hierarchies). Update files after sending without re-uploading. Forward existing transfers to new recipients. File request system for collecting documents from suppliers, clients, or partners. Everything email and WeTransfer can't handle.
Business Intelligence and Download Tracking
Know exactly when, where, and how your files are accessed. Real-time geo-location tracking shows you which countries and cities downloaded your files. Device information (mobile/desktop/OS), IP addresses, and access timestamps provide complete visibility. Track trade show catalog opens, RFQ engagement, and buyer interest. Email read receipts are unreliable; Sinosend gives you certainty.
Privacy, Security, and Compliance as Standard
GDPR, SOC2, and CCPA compliant with transparent security practices. Bank-grade AES encryption at rest, TLS 1.3 in transit. Complete audit trails logging every file access, download, and modification—critical for accounting firms, legal professionals, and regulated industries. Password protection, expiration dates, view-only modes, and instant revocation controls. We don't just move your data; we protect it with enterprise-grade security available to all users.
Rapid Innovation: Shipping Machine
We don't believe in "finished." We ship new features every week based directly on user feedback and roadmap voting. Voice memo attachments for personal touches, Meta Open Graph support for professional social sharing, file request validation, team collaboration tools—every feature solves a real-world pain point we've experienced or customers have requested. Join our public roadmap at sinosend.com/roadmap.
