Top SchoolJelmer De Jong is a seasoned technology and product leader with 12 years of experience building and scaling B2B software, fintech, and go-to-market organizations, currently serving as CTO and Partner at RTP Global where he builds a Venture Capital Operating System focused on data intelligence and digital investigation.

An active investor and board partner, he evaluates and backs startups across ML/AI, cybersecurity, infrastructure, and enterprise software, bringing operator experience to his investments. Based in Amsterdam, he combines startup grit—from founding a digital agency—to enterprise-scale product strategy, making him equally fluent with early-stage product-market fit and large-scale product commercialization.
