’Disruptive Innovator’ Category Winner: SAICA Trainee Trailblazer Awards 2025

Pieter Pienaar is an Academic Trainee at the University of Pretoria whose work is transforming accounting education through artificial intelligence, advanced analytics, and a bold commitment to innovation.

Pieter developed a series of custom machine learning models designed to simulate real-world professional interactions. These AI bots are not generic chat tools — they are tailored assessment engines that replicate authentic client scenarios, enabling lecturers to test SAICA competencies in real time. Students engage with these bots to navigate complex situations, such as defending ethical positions or communicating with clients, offering a level of realism and unpredictability that traditional exams often miss.

The impact has been profound. Students describe the bots as “challenging,” “realistic,” and “memorable,” with one noting, “I’ll remember IFRS 18 because of this bot.” Others shared how the process of failing and reattempting deepened their understanding more than any written assignment could. Pieter’s work has created learning moments that stick — changing how students think, learn, and grow.

These innovations have already gained international recognition. Pieter’s AI projects have been showcased at leading conferences across South Africa and Europe, including the BAFA conference in Dublin, the TRN conference in Nottingham, and the SAICA Education Symposium. His work has attracted interest from the International Federation of Accountants for potential global rollout, reinforcing the relevance of professional accountants in a rapidly evolving world.

Beyond AI, Pieter is a champion of advanced problem-solving. In 2024, he ranked 2nd globally in the Microsoft Excel Collegiate Challenge, becoming the highest-ranked South African competitor in the event’s history. He later founded the University of Pretoria’s Excel Club, where he shares his expertise in advanced analytics and big data with his fellow students.

Pieter is currently completing his master’s degree in accounting while serving on SAICA’s AI Policy Working Group, contributing to the strategic direction of technology in the profession. He also brings creativity and discipline to his personal life — as a skilled pianist, he is working toward his Trinity ATCL Performance Diploma, reflecting his pursuit of excellence across domains.

At his core, Pieter believes that Chartered Accountants must be leaders who challenge the status quo and consistently create meaningful impact. His work is not just about technology — it’s about reimagining education, empowering students, and ensuring the profession evolves with purpose.
