Byterise publishes apps. They handle marketing, growth, analytics, and financing for developers across a portfolio of titles. For one launch, they had a concept that worked in early tests and a deadline. 12 markets, three formats each, localized hook variants, all before the budget cycle closed.
Old math: 12 markets × 3 formats × ~7 hook variants ≈ 250 assets. At their internal production rate, manual delivery would have taken about six weeks. They had ten days.
Echo turned the concept into 240 on-brand variations by end of day. Formats swapped, hooks rotated, copy localized per market. Byterise put the batch into testing two days later. The team that would have spent six weeks building variations spent those six weeks reading results.
