Hey Product Hunt 👋,
We built Prevent after experiencing “digital shoplifting” firsthand - losing revenue, products, and time to customers who knew how to game the chargeback system.
Most fraud tools only catch pre-transaction fraud, leaving friendly fraud and post-purchase abuse unchecked.
What makes prevent different:
✅ Actor-based analysis → focus on the buyer, not just the transaction.
✅ Post-transaction detection → drastically fewer false positives.
✅ Collaborative network → 15,000+ merchants sharing real-time data.
✅ Digital Score → a transparent score (0–100) that answers: “Can I trust this client?”
We’re most proud that Prevent helps SMBs accept more good orders with confidence instead of turning away revenue.
Would love your thoughts, feedback, and support 🚀

Big fan of this space 🙌🏻 One thing I’m wondering — can Prevent work alongside existing tools like Riskified/SEON?
Chargeflow
@roypovar Hey Roy. Prevent can definitely work alongside any fraud prevention solution/platform because of how uniquely it is built.
Instead of blocking transactions at checkout, Prevent stars working right after the checkout has been complete, running it through advanced ML algorithms and assessing the customer trustworthiness through our vast network, consisting of 15,000 merchants. Most fraud solutions are looking only at the transaction elements such as the credit card AVS, CVV, billing and shipping addresses, which are important for fraud prevention but not friendly fraud. Prevent is assessing a customer based on his past online purchase, chargeback and returns behavior, which is crucial to prevent friendly fraud.

Really impressive launch guys 👏🏻
Quick question: what makes your Digital Score different from traditional fraud scores? Interesting to hear that
Chargeflow
@mituhin Thanks Paul. Digital Score is buyer-first, not transaction-first. It blends post-checkout behavior, repeat-abuse history (chargebacks, returns), and network outcomes across 15k+ merchants into a time-aware 0–100 score with factor-level explanations. Traditional scores stop at checkout signals. We step in after payment to gate fulfillment and cut false declines. Want a screenshot of a score explanation?

Congrats on the launch! I've had a few disputes with a small <1M brand and they were annoying to deal with. At what scale does it make sense to use this?
Chargeflow
@seanlewin Thanks for this. Prevent is designed to be useful whether you’re running a small brand or a large enterprise. Smaller stores benefit from not having to fight disputes manually or lose revenue to “digital shoplifters.”
Larger stores benefit from scale, catching repeat abusers across thousands of orders and cutting operational overhead. Because pricing is usage-based and starts with 1,000 free scans, it’s flexible enough to make sense from day one and still powerful as you grow.
Curious, in your own disputes, were they mostly “item not received,” subscription cancellations, or something else?

Thanks for checking out our launch on Product Hunt! 🙌
Building Chargeflow Prevent has been a journey driven by countless conversations with merchants—from founders running their business out of a kitchen table to operators at global brands. The frustration was always the same: revenue slipping away to disputes that shouldn’t exist.
Not from hackers. Not from stolen cards. But from something far more common: friendly fraud and refund abuse.
We realized the hard truth: existing fraud tools weren’t designed for this reality. They looked at single transactions in isolation, while fraudsters were exploiting identity patterns across brands. Fraud had evolved, but prevention hadn’t.
So we built Prevent:
⚡ Identity-first scoring powered by data from 15,000+ merchants
⚡ Post-purchase protection that flags fraud before fulfillment
⚡ Automated decisions - approve, verify, or cancel; so merchants can grow without babysitting dashboards
This wasn’t about creating yet another fraud filter. It was about rethinking prevention entirely: moving merchants from reactive defense to proactive protection.
We’re incredibly proud of the team that brought this to life, and equally excited to learn from the Product Hunt community as we continue building.
If you’re a merchant (or just curious about fraud prevention in 2025-26), we’d love your thoughts, feedback, or questions. The best products come from conversations like these.
Here’s to helping merchants grow fearlessly. 🚀

@ariel_chen1 Couldn't have done this without you, brother and partner. We're changing the industry, one step at a time!
Congrats on the launch team. What kind of access would you need to a Stripe account to monitor it for fraud? And do you do the work to fight the fraud or do you just notified me via email or something?
Chargeflow
@kensavage Hey Ken, thank you. Prevent has launched for Shopify right now, if you're using Shopify with Stripe, it automatically works and does not need to integrate with your Stripe account. We'll be launching our direct Stripe integration pretty soon and will require minimum permissions.
Regrading monitoring or taking action - Prevent has a built-in next generation workflow builder that allows you to auto-approve, put on hold (for further verification) or cancel orders based on their risk score and many other parameters.
Rock on, Gents! rock on! love it
Chargeflow
@arielcohen Thank you so much!
Oh that’s really cool! Does Prevent reduce false positives compared to other fraud tools?
Chargeflow
@mia_k1 Thanks Maria! Yes, that’s one of the big advantages. Prevent doesn’t block orders at checkout, so you avoid the false positives most fraud tools cause. Every order goes through first, then Prevent analyzes it post-checkout and recommends the right action: approve & ship, verify the buyer, or cancel. This way merchants maximize sales while still stopping fraud.
