I Understood the Problem. I Still Built the Wrong Product.

Short summary

A CTO at a UK edtech startup recounts building a technically sound product that solved the right problem with the wrong solution, leading to a full rewrite. The lesson: understanding the problem does not guarantee understanding the right solution, and testing assumptions before coding is cheaper than rebuilding months later. The post ends with social links and self-promotion.

• •Understanding the user's problem doesn't mean you've found the right solution
• •The team scrapped months of work after a demo revealed mismatched assumptions
• •Author now spends more time questioning assumptions before writing code
