Core offering

Sendy develops and operates the Rakuten Drive platform, which combines high-speed large file transfer (up to 50GB per transfer) powered by Sendy's Send Anywhere technology with cloud storage of up to 3TB per user. The service enables secure file sharing through expiration dates, password protection, and shared folder permissions, and integrates directly with workplace messengers such as Slack and Chatwork as well as email systems for seamless business file collaboration.

Product overview

Rakuten Drive is a unified cloud storage and file transfer platform offered by Sendy under the Rakuten Mobile, Inc. umbrella. The platform comprises two core services—Rakuten Drive Transfer for high-speed large file transfers (up to 50GB per transfer) and Rakuten Drive Cloud for scalable cloud storage (up to 3TB per person). These are complemented by two subscription tiers: Rakuten Drive PRO for individual users and Rakuten Drive Business for teams and organizations requiring collaborative features. The platform emphasizes security with password and expiration date settings, and integrates with popular work communication tools like Slack and Chatwork for seamless file sharing.

Direct peers

• Box: Box is a direct peer in the cloud storage and team file collaboration space, with a stronger enterprise focus. It competes with Rakuten Drive Business on shared folders, permissions, expiration controls, and team administration — and offers a mature public API that Rakuten Drive currently lacks.
• Dropbox: Dropbox is the most well-known direct peer in the file sync, sharing, and cloud storage category. Like Rakuten Drive, it offers freemium storage tiers, large-file transfer, and team collaboration features; the two compete for the same horizontal individual and SMB use case.
• WeTransfer: WeTransfer is a direct peer in the large-file transfer space, supporting transfer of very large files via link-based sharing. Rakuten Drive Transfer's 50GB-per-file capability is the most direct functional overlap with WeTransfer's core offering.
• Filemail: Filemail is a direct peer in the large-file transfer and cloud delivery category, offering both ad-supported and business plans. It is highly comparable to Rakuten Drive Transfer for use cases involving very large file exchanges between teams and external recipients.

Broad incumbents

• Microsoft OneDrive: Microsoft OneDrive is a broad incumbent bundled into Microsoft 365, offering cloud storage, file sharing, and tight Office integration. Enterprise buyers in Japan and globally usually have OneDrive already included, which constrains incremental spend on standalone storage products like Rakuten Drive.
• Google Drive: Google Drive is a broad incumbent that bundles 15GB of free storage into the Google account ecosystem and is part of the Google Workspace productivity suite. It competes across both consumer and business tiers and is typically the default for teams already on Workspace.

Emerging players

• pCloud: pCloud is an emerging player in the consumer/SMB cloud storage space, offering lifetime and subscription plans. It overlaps with Rakuten Drive's freemium-to-paid individual motion and competes on per-GB pricing.
• MASV (Massive.io): MASV is an emerging player in large-file transfer and delivery for media and creative teams, competing with Rakuten Drive Transfer on high-volume, high-speed transfers. It is particularly relevant as a peer for media/creative professional segments that also value Rakuten Drive's 50GB-per-transfer capability.
• SendSafely: SendSafely is an emerging player in secure file transfer and encrypted file sharing, competing in the same secure large-file transfer niche as Rakuten Drive Transfer. It focuses more on end-to-end encryption for regulated industries, offering a useful comparison point on security-focused positioning.
• Sync.com: Sync.com is an emerging player in privacy-focused cloud storage and file sharing with end-to-end encryption. It overlaps with Rakuten Drive on storage and team sharing, with a differentiated emphasis on zero-knowledge security that competes for the same privacy-conscious business customers.
