Code Ninety built a payment platform that now processes 500,000+ transactions a month, with a 99.98% success rate and zero payment fraud incidents in its first year.
You send $100 to a friend. It arrives in 1.8 seconds.
Here’s what happens in between:
1. The app checks your balance.
2. The platform debits your wallet.
3. A fraud model scores the payment in about 200 milliseconds. It weighs 47 signals, from transaction amount to device and account history.
4. If it’s approved, your friend’s wallet is credited.
5. A push notification lands on their phone.
We built that flow for a North American fintech startup that had outgrown a no-code MVP handling about 2,000 transactions a month. In 9 months, our 16-engineer team delivered a platform that passed its PCI-DSS audit with zero findings, three months ahead of the original timeline.
Twelve months later:
Registered users grew from 12,000 to 500,000+
$840,000 in fraudulent transactions blocked, with a false positive rate of just 0.12%
180 transactions per second handled at peak with no slowdown
The startup raised an $8M Series A on the strength of its growth
Behind a result like this are people who care about the details no user ever sees. Shayan, Senior MLOps Engineer, was one of the team members behind the machine learning work that kept this platform safe at speed. Congratulations to him and the team.
Which matters more when you choose a payments partner: speed, security, or compliance?
