P7M.io — Italian digital signature reader

Italy mandates CAdES digital signatures (.p7m) for public-sector invoices, contracts and court filings — and nothing on Windows, macOS, iOS or Android opens them natively. P7M.io reads them in the browser, with no upload: the file never leaves the device. Three channels on one codebase: a web app, an iOS app and an Android app. Ranked #3 on Google for the core queries, 40,000 organic clicks a month, zero paid acquisition, zero staff.
