Milestone day at Chargeflow. We raised 35M and unlocked the next chapter 🏆

Chargebacks and transaction denials have drained online merchants for years – costing billions in revenue. We’re proving there’s a better way.

Building AI-driven technology that delivers measurable outcomes has been one of the most meaningful challenges of my career, and doing it through PLG makes it even more rewarding.

We’re solving this problem at scale and turning a historically costly failure point into a predictable outcome. The next phase is where things accelerate.
