• South African entrepreneur leads The Invigilator, an e-learning integrity platform

• AI-powered app detects irregularities during online assessments

• Also cofounder of Nova Messenger for large-scale group communication

Nicholas Riemer, a South African entrepreneur and chartered accountant, is the cofounder and CEO of The Invigilator, an education technology company that helps institutions ensure the integrity of online exams.

Founded in 2020 during the Covid-19 pandemic, The Invigilator developed a digital solution to safeguard remote assessments as schools and universities increasingly adopted online learning. The application monitors exams without requiring specialized equipment or high-speed Internet access.

The platform uses artificial intelligence to detect suspicious behavior through a student’s smartphone. Its algorithms analyze movements, background sounds, and interactions to alert examiners to any irregularities. It also features a linguistic analysis tool designed to identify assignments or essays generated by AI systems.

Riemer is also the cofounder and CEO of Nova Messenger, launched in 2023, which enables instant messaging among large groups of learners, employees, or members without phone numbers or limits on group size or file sharing.

Since 2019, he has served as head of investment education at FNB Wealth and Investments, a South African asset management firm. A graduate in accounting from the University of Johannesburg, Riemer began his career in 2012 at Hollard Insurance, working on mergers and acquisitions operations.
