Amplitude, Inc. is an American publicly traded technology company that develops a leading digital analytics platform and experimentation tools designed to help organizations optimize their digital products and better understand user behavior. Originally founded under the name Sonalight, Inc. in 2011 by Spenser Skates, Curtis Liu, and Jeffrey Wang, the company initially focused on an Android voice-texting application. While building this app, the founders developed internal analytics software to track user interactions. Recognizing significant market interest in this software from other businesses, they strategically shifted their focus. The company officially rebranded to Amplitude, Inc. in December 2014 and launched its core product, Amplitude Analytics. Headquartered in San Francisco, California, Amplitude has grown to employ over 800 individuals globally across offices in the United States, Europe, and Asia. The company operates on a cloud-based Software-as-a-Service (SaaS) subscription model, delivering its applications over the internet to a diverse and expanding global customer base. Amplitude's comprehensive Digital Optimization System features an extensive product portfolio. This includes Amplitude Analytics, which provides real-time, event-based insights into user behavior; Amplitude Session Replay, a qualitative tool that reconstructs user journeys via heatmaps and session playbacks; and Amplitude Feature and Web Experimentation, which allows engineering and product teams to run A/B testing with reduced infrastructure needs. Additionally, the platform integrates advanced artificial intelligence capabilities through features like Amplitude AI Feedback, an LLM-powered engine that transforms raw user input into structured, actionable insights, and Ask Amplitude, which enables conversational data querying. Amplitude serves more than 3,000 paying customers, including industry giants such as Atlassian, Shopify, Under Armour, NBCUniversal, and Jersey Mike's. The company has aggressively expanded its market reach and product capabilities through strategic acquisitions, notably absorbing predictive analytics firm ClearBrain in 2020, data pipeline company Iteratively in 2021, user engagement startup Command AI for $45 million in October 2024, and marketing analytics platform InfiniGrow in January 2026. Financially, Amplitude raised approximately $336 million in private venture funding from prominent institutional investors, including Sequoia Capital, Battery Ventures, Y Combinator, and IVP, achieving a private valuation of $4 billion. Moving away from traditional IPO norms, the company went public via a direct listing on the Nasdaq stock exchange on September 28, 2021, trading under the ticker symbol AMPL. The company is currently led by co-founder and CEO Spenser Skates alongside CTO Curtis Liu. For the trailing twelve months concluding in early 2026, Amplitude reported a robust annual revenue of $357 million, securing its position as a top-tier category pioneer in behavioral graph database technology and modern product analytics.
