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. He blends hands-on product and engineering leadership with growth and marketing expertise from senior roles at Backbase and eFresh, helping companies scale product, sales, and international expansion.

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.
