James Teller has spent the last eight years focused on a single mission: making online dating safer for everyone. With a background in cybersecurity and digital consumer protection, he brings a specialist lens to an area most dating reviewers overlook. James evaluates every platform’s verification systems, moderation practices, data handling policies, and privacy controls to determine whether a site truly protects its users or simply claims to.

Before joining Datingroo, James worked as a digital fraud analyst for a consumer advocacy organization, where he investigated romance scams, catfishing operations, and data breaches affecting dating platform users. His research has been cited in publications covering online safety, and he has consulted with several platforms on improving their trust and safety infrastructure.

At Datingroo, James leads the safety and privacy component of every platform review. He developed the security evaluation framework that underpins our scoring methodology, ensuring that no platform receives a strong recommendation without meeting rigorous standards for user protection. He also authors our safety guides and educational content, helping readers recognise red flags, protect their personal information, and approach online dating with confidence.

Outside of work, James is an amateur chess player, a dedicated home barista, and someone who will always check the privacy policy before downloading an app.
