Madison Small Cap Fund stated the following regarding Amplitude, Inc. (NASDAQ:AMPL) in its fourth quarter 2025 investor letter:
“Amplitude, Inc. (NASDAQ:AMPL) has undergone a significant turnaround that has gone largely unnoticed since new CFO Andrew Casey joined the company to reboot the sales force and manage the company for profitable growth and free cash flow. Amplitude is a leader in digital analytics software that tracks, analyzes, and predicts user behavior across digital products (web and mobile). Its software helps product teams understand which features drive engagement, retention, and revenue. The economic quality is characterized by a highly recurring service revenue model, strong gross margins, and a recent inflection toward positive free cash flow. The company’s primary protective moats are the extremely high switching costs for customers. Migrating a deeply embedded analytics system involves re-tagging all events, retraining teams, and potentially losing historical data, making it costly and disruptive. The balance sheet is pristine with no debt and almost $270m in cash. The company went public during the 2021 software Initial Public Offering (IPO) frenzy at an extremely high valuation and has been largely forgotten over the last few years as it has undergone a turnaround. Andrew Casey’s resume is very impressive, with a background in tech giants Hewlett-Packard and ServiceNow. We believe the current valuation is extremely attractive and estimate the intrinsic value to be $21.”
