Update your address, phone, or name once. Every connected organisation gets it automatically — no more filling in the same form for the council, bank, and broadband provider separately. For businesses: address verification that's usually a one-off snapshot, gone stale the next day. ContaShare makes it live — webhooks fire the instant a customer's details change. Free for individuals. 50 free API credits for businesses, no card required.








Hey PH! Founder here 👋
Last year I moved house and spent an entire evening updating my address with the council, bank, broadband provider, and every subscription I'd ever signed up for, separately, one by one. One company even sent me a letter asking me to confirm the letter I'd sent them.
I built ContaShare so that never has to happen again. You update your details once, and every organisation you've connected gets the new version automatically.
The B2B side came later, once I realised companies have the mirror image of this problem. They pay for address verification that's accurate for exactly one day, then quietly goes stale. ContaShare replaces that one-off check with a live feed instead.
Would love your honest feedback, especially if you've moved recently, or work in fintech, insurance, or utilities and deal with this from the other side. 🙏
