South African edtech startup The Invigilator, which develops AI-powered software to prevent cheating during online assessments, has secured an R195m ($11m) funding round.
The investment was led by Kaltroco, a private, single-family-backed investment firm based in the Channel Islands. The funding is earmarked for a significant international expansion push into North America, Europe, Asia and the Middle East.
Why it matters: The deal highlights investor confidence in the remote assessment market, which saw explosive growth during the Covid-19 pandemic. However, startups in the space face a dual challenge: navigating student privacy concerns and keeping pace with increasingly sophisticated cheating methods, including the use of generative AI tools like ChatGPT.
What does The Invigilator do?
Founded in 2020, The Invigilator provides a platform for educational institutions to monitor students during remote exams and assessments. Its primary goal is to uphold academic integrity in an online setting.
- The tool uses a student’s smartphone to monitor their activity during an exam, using AI to flag suspicious behaviour.
- The company says its approach is designed to be cost-effective and function in low-bandwidth environments, a key consideration in its home market and other emerging economies.
- Earlier this year, it launched a new feature specifically designed to detect when students have used AI to write assignments or assessments. The company claims its tool builds a unique “writing profile” for each student, allowing it to identify text that deviates from their established style.
The Invigilator already has a significant footprint in Southern Africa, with over 100 institutions including Varsity College, Boston City Campus and Curro Academy Schools using its platform.
The growth plan
The fresh capital will be used to refine its AI models and expand its product’s capabilities.
“This investment gives us the ability to ramp up AI development,” said cofounder and CEO Nicholas Riemer. “The creation of our live AI monitoring technology means The Invigilator is moving to constant assessment monitoring through AI.”
The company also plans to add multilingual support to the platform and build out operational teams in its target international markets.
The investor
The choice of Kaltroco as a lead investor is notable. As a single-family office, it is not bound by the typical fund lifecycle of a traditional venture capital firm. This “patient capital” approach allows for longer-term investment horizons, which could give The Invigilator the runway it needs to navigate the complex and competitive global edtech market. Kaltroco has previously made around 30 investments globally.
The Invigilator’s funding is a significant endorsement for the South African tech ecosystem, demonstrating that local solutions can attract international capital. The company is tackling a genuine pain point for educational institutions worldwide, which are struggling to maintain credible assessment standards as learning moves online.
However, the path to global scale is not without hurdles. The remote proctoring industry has faced criticism over student privacy, with some tools seen as overly intrusive. The Invigilator will need to carefully balance security with user experience as it enters Western markets where these concerns are particularly acute.
Furthermore, the company is in a technological arms race. As its AI detection tools become more sophisticated, so will the tools used to circumvent them. Its success will depend on its ability to innovate faster than those looking to cheat the system. Securing a long-term investment partner like Kaltroco provides a solid foundation for this marathon, not a sprint.
