Deep dives
The Spark that Led to Reviews.io
In 2012, during a challenging financial phase, Callum McKefree's conversation with a major mobile phone company sparked the idea for Reviews.io. Although his initial startup ideas were rejected, one question about their customer review processes triggered him to create a rough MVP. This led to a focused effort, where he hustled to acquire initial customers through cold calling and guerrilla marketing tactics, including attending expos with engaging elements like a foosball table. Over 18 months of hard work, he reached his first million in Annual Recurring Revenue (ARR), proving the potential of his idea against competitors.
