Questions & Answers

As answered by people managing Project Euler and CubbyDrop.

What makes your product unique?

CubbyDrop's answer:

CubbyDrop is the only file sharing service that combines end-to-end encryption with peer-to-peer Live transfers via WebRTC. Files are encrypted in your browser before upload — not even CubbyDrop can access them. It also offers encrypted text/pastebin sharing, which no other file transfer service provides.

How would you describe the primary audience of your product?

CubbyDrop's answer:

Privacy-conscious professionals, freelancers, and teams who share sensitive files — legal documents, contracts, financial records, medical files, API keys, or code. Anyone who needs to share files without trusting the server.

What's the story behind your product?

CubbyDrop's answer:

CubbyDrop was built out of frustration with existing file sharing services that claim security but can still access your files. I wanted a service where encryption happens in the browser before anything leaves your device, with zero-knowledge architecture that makes it technically impossible for the provider to see your data.

Who are some of the biggest customers of your product?

CubbyDrop's answer:

CubbyDrop is an early-stage bootstrapped product serving individual professionals and small teams who prioritize privacy. We're focused on organic growth through word of mouth.

Let me know when you're done and I'll give you #3.

Why should a person choose your product over its competitors?

CubbyDrop's answer:

Unlike WeTransfer, Google Drive, or Dropbox, CubbyDrop uses true zero-knowledge encryption — the server never sees your files or encryption keys. Live mode transfers files directly between devices with no size limit. Free tier includes 5GB storage, and recipients never need an account to download.
