Hirosend▲90I built Hirosend because I needed a fast and secure way to send files to clients without asking them to create accounts or navigate permission screens. Dropbox/Drive were too heavy for one-off transfers, WeTransfer felt clunky for quick sends, and I really missed the simplicity Firefox Send had before it shut down.
