Amplitude is a digital analytics platform centered on product analytics, helping companies understand user behavior across their web and mobile products and connect that behavior to business outcomes like conversion, retention, and revenue. Teams instrument events, then use Amplitude to build funnels, retention and engagement analyses, user journey maps, and behavioral cohorts, with a governance layer for keeping tracking plans consistent as organizations scale. Beyond core analysis, Amplitude has expanded into a broader suite that includes experimentation and feature flagging, customer data management with the ability to sync audiences to downstream marketing tools, session replay, and web experimentation, positioning itself as a platform spanning analytics, testing, and activation. Its AI assistant lets users ask questions in natural language and get charts and explanations back. Amplitude is used by product, growth, marketing, and data teams to prioritize roadmap work, measure launches, and personalize experiences. It publishes widely read benchmarks and frameworks on product-led growth. The company offers a free plan for smaller teams and usage-based paid plans, and it serves customers from startups to large public enterprises across consumer and B2B software, media, e-commerce, and financial services. Amplitude also provides a warehouse-native deployment option so customers can run analysis directly on data in their own cloud warehouse rather than duplicating it into a separate system.
