In one paragraph
Amplitude is the analytics tool you buy when you have a data team. It's deep, configurable, and assumes someone on staff lives in chart builders. Millimetric assumes you have neither the time nor the staff — and that an LLM can fill the role of the chart builder if you ask it nicely.
Pick Amplitude when…
- You have a data team and they live in Amplitude already.
- You need governance, taxonomies, and centralized event definitions.
- You're past series B and analytics is a department, not a side quest.
Pick Millimetric when…
- You're under 20 people and 'data team' is a tab in your browser.
- You're more likely to ask Claude for a number than open a chart builder.
- You want predictable monthly cost, not 'contact sales.'

Our verdict
Amplitude is right for orgs that staff analytics. Millimetric is right for orgs that don't — and don't plan to.
