So here’s what’s going on :
Your tech stack is a mess.
Legacy code, rushed patches, outdated architecture — all slowing your team down like quicksand in a footrace.
You’re scaling... and breaking at the same time.
User growth is great — until your app lags, payments fail, and your database catches fire during peak traffic.
Fraud is coming through the cracks.
Bots. Fake IDs. Stolen cards. You're spending more time playing security whack-a-mole than building features.
Users drop off faster than you can onboard them.
KYC is slow. Onboarding is clunky. And one failed transaction? Say goodbye to that customer forever.
Your support team is drowning.
Payment failures. Login issues. Bugs that slipped through under pressure. Your team is firefighting 24/7.
Compliance is a full-time job — and it’s not even your product.
You’re juggling PSD2, AML, PCI, GDPR, SOC2… and the alphabet never ends.
And you’re running out of time.
Deadlines loom. Investors want results. Burn rate's rising. The pressure to ship is brutal — but every shortcut adds another crack in the foundation.
Sounds familiar? Good — that means you’re finally seeing it clearly.
Now let me show you how we flip this entire mess into momentum.
Collaborating together, I’ll help you dramatically improve in the
