The problem with your card is that everyone has it. Every subscription, trial, and one-off purchase sits on the same 16 digits, stored on servers you'll never see. When one gets breached, you're the one who notices the strange charge, calls the bank, and updates it everywhere. Sitra starts with one idea: your card doesn't have to be permanent. Not a bank. Not a budgeting app. Just a card built to be thrown away. Disposable by default. Under your control, always.
Hey Product Hunt 👋
I'm the solo founder behind Sitra.
This started from something small and annoying: I signed up for a free trial, forgot to cancel it, and got charged for four months before I noticed. Not a huge deal financially,but it bugged me. I gave a company my real card number for a $0 trial, and I had zero control over what happened next.
I started paying attention, and the pattern was everywhere. Every site I bought from once, a random SaaS tool, a one-time purchase, a trial I wasn't sure about, got the same card as my rent and my groceries. If any one of those got breached, I'd find out the same way I always do: a weird charge, a call to the bank, a new card, and an afternoon updating it everywhere.
The obvious fix is also the simplest one: don't give the same card to everyone. Give each purchase its own card, and let it expire when you're done with it.
That's all Sitra is right now. Generate a card. Set a limit. Set an expiry. Use it once. It deletes itself. Nothing clever, nothing hidden, just a card that doesn't stick around longer than it needs to.
Sitra is currently in development, but before investing months into building the platform, I want to make sure I'm solving a problem that genuinely matters. This waitlist is my way of learning from early adopters, validating demand, and building the right product, not just building fast.
A few things I'd genuinely love your take on:
1. Where does this bite you the hardest — subscriptions, free trials, one-off purchases, something else?
2. Would you actually want a new card for every merchant, or is that overkill?
3. What would make you trust a virtual card provider you'd never heard of?
I'll be in the comments all day. Tell me if this is useful, tell me if it's not, both help.
