Revenue growth measures how quickly a company's top-line sales are expanding year-over-year or quarter-over-quarter, and it is often the first metric investors examine when evaluating growth companies. For early-stage or unprofitable businesses, revenue growth may be the primary signal that the core business model is working and gaining scale. The growth rate matters: decelerating revenue growth — where the company is still growing but at a slower pace — often leads to multiple compression because investors price growth trajectories, not just current revenue levels. High revenue growth alone is not sufficient if it comes at an unsustainable cost, so it is typically evaluated alongside gross margin, operating leverage, and customer retention metrics. Comparing revenue growth to direct peers in the same sector provides important context — a 15% grower may be excellent in a mature industry but disappointing in a sector growing at 40%.
