While one wouldn't think an alternative was needed for iron supplements, it turns out they taste terrible. As a result, two-thirds of the people that need more iron stop taking the pills.
Enter the little Lucky Iron Fish. It looks like little more than a paperweight. But boil it in a pot of water for 10 minutes and the resulting liquid has enough iron to meet someone's nutritional needs. Plus it lasts for five years, making it more affordable in the long term than taking a daily pill.
Lessons we can learn: Inside that little metal fish are also some good lessons for any tech entrepreneur. It's proof that sometimes problems that appear to be solved, really aren't. And, sometimes a completely new approach may be needed. Plus, the shape of the fish is a reminder that design matters. Initially, it was just a little iron disk, but when Gavin Armstrong was developing it for use in Cambodia, he found people were much more likely to use a fish-shaped object because fish are considered lucky there.
