About Sedum
Sedum was founded on a simple belief: compliance training should be clear, structured and thoughtfully designed.
We work with Australian organisations to create learning environments that reduce cognitive overload and create confidence.
Every design decision is made to support focus, comprehension and practical use in the workplace.
The problem
Typically, workplace training is built for completion rates rather than comprehension. Dense slides, overuse of games and awards, cluttered visuals and noise often overwhelm learners and dilute important information.
And as technology evolves… even more gets added.
Research in cognitive load theory demonstrates that when working memory is overloaded, retention declines.
We believe learners deserve better. Businesses have enough on their plates.
Compliance should be simple.
“I didn’t start Sedum because I wanted to create more training. I started it because I wanted to create better learning experiences. I noticed how often workplace training felt overwhelming, and how that slowly chipped away at people’s confidence. I believe learning should feel steady, safe and considered. That belief shapes everything we design.” Rhiannon
