Amplitude

Amplitude is a product and marketing analytics platform with a customer data pipeline, session replay and experiments, and unlimited seats on every plan.

Amplitude is a digital analytics platform that shows how people move through a product and what they do next. It joins product and marketing analytics to a customer data pipeline, so the events a team collects feed both the charts and the tools downstream. Amplitude, Inc. builds it in San Francisco, launched it in 2014 and runs as an independent public company on Nasdaq. It suits teams whose decisions depend on what happened inside the product rather than on what a survey says about it. Analytics answers questions about conversion, retention, sessions and stickiness with charts anyone on the team can build. Session Replay plays back the individual sessions behind a number, and heatmaps show where attention lands on a page. Feature Experiment runs flags and tests in the product, while Web Experiment changes a page without a deploy. Guides and Surveys puts onboarding nudges and questions in front of a chosen segment. Amplitude Data sits underneath, holding events to a tracking plan, merging anonymous and known activity into one user, and streaming the result to other tools. Product managers, growth marketers and analysts are the everyday users, and the engineers who instrument the events are the people who set it up. Small teams looking for product-market fit start on the free plan and stay there while their event volume is low. Larger organizations come for portfolio-level projects, role-based access control and the option to hold data in the EU. Amplitude is bought as one platform with unlimited seats, charged by the volume of events a business sends, and the plan cards list every tier. Teams reach for it when a launch needs measuring, when a funnel drops off for no obvious reason, or when an experiment has to show a change was worth shipping. Marketing teams follow a campaign past the click into signup, activation and revenue, converting currencies where a business sells in several. The source catalog pulls from tools such as Stripe and RevenueCat, and the destination catalog sends cohorts and events to Marketo, Salesforce Marketing Cloud, Google Ads and warehouses including Snowflake, BigQuery and Redshift. With a warehouse-native mode that queries Snowflake in place, Amplitude sits beside a company's data stack instead of replacing it.
