The £2.5 Million Agency Disaster: Why 82% of Successful Mobile Apps Use Specialised Agencies
In 2010, Groupon was the fastest-growing company in history, but their mobile app development agency had built a platform that couldn’t handle their explosive growth. The result? Frequent crashes, lost transactions, and a £2.5 million emergency rebuild that nearly destroyed the company. The difference between success and failure often comes down to one critical decision: choosing the right mobile app development agency.
While 68% of businesses initially consider hiring individual developers to save costs, the smartest companies are discovering that mobile app development agencies deliver better results, faster timelines, and higher success rates at a lower total cost of ownership.
