Rayan Dawud
Product Manager at Cercli (YC S23)
With Big Tech increasingly complicit in actions that compromise fundamental privacy and human rights, I made the switch from Google to Proton for both email and file storage about a month ago. And honestly? I’m never going back.

I recently switched to Proton for email/calendar/files and I was pleasantly surprised. Everything worked seamlessly, and the transition was super easy with the “Easy Switch” feature.
For SMBs, it’s definitely worth serious consideration if you’re starting something new now, working in emergency preparedness, security, or in (humanitarian/political) organizations.
