Honestly this started from a problem I kept running into while working in IT. Every time a new hire started, I had the same headache. How do you get someone their login credentials before they have access to anything? Their company email isn't set up yet. Their laptop isn't configured. They're standing there on day one and the only option I had was to send a password over personal email or Slack and just hope nobody was watching. I knew it was wrong every time I did it. But what else was I supposed to do? Then I started thinking about how many other people deal with the exact same thing. The HR manager emailing social security numbers as attachments. The lawyer sending settlement figures over Gmail. The real estate agent emailing wiring instructions that fraudsters are literally hunting for right now. The person texting a passport scan to a landlord they just met. Every industry. Every profession. Same problem. Same crossed fingers. The tools that existed were either basic self-destructing note apps with no way to verify who actually opened the link, or full enterprise platforms that cost a fortune and require everyone to already have an account. Which defeats the whole point when you're trying to reach someone who doesn't have access to anything yet. So I just built the thing I wished existed. Your file gets encrypted in your browser before it ever touches our servers. The only way to unlock it is with something the recipient already knows, their laptop serial number or their phone number. So even if someone intercepts the link it's completely useless without that code. We genuinely cannot read your files. Not won't. Can't. That's just how it works technically. The thing I'm personally most proud of is the honeypot detection. Every link quietly generates a decoy URL alongside it. If anyone probes or tries to intercept your link, that tripwire fires instantly, the file is destroyed and you get alerted before the real link is ever touched. I've never seen another tool in this space do this. What started as a solution to an IT problem turned into something I think is useful for pretty much everyone. Sensitive data isn't just an IT thing. It's a human thing. And nobody deserves to send something important and have to cross their fingers afterward. That's really why I built it. Would love to hear what you think, good or bad. Happy to answer anything.

Just to clarify, SendOnce isn't just an IT tool. It was originally built to solve a problem I kept running into in IT support but the use case goes way beyond that.

HR teams dealing with social security numbers, offer letters, and onboarding documents. Legal teams sending contracts, settlement figures, and privileged communications. Finance teams sharing bank details, tax returns, and wire transfer instructions.

Anyone who handles PII or confidential information and needs a secure way to deliver it over the internet without relying on email or Slack.

If your job requires you to protect sensitive data and you've been crossing your fingers every time you hit send, this was built for you too.
