Retention & behavioural cohorts
Retention is the marquee chart — and the cohorts that make it useful are tier-gated, with the Plus plan capping how many you can save.
What people actually say
✕Behavioural cohorts on Plus are hard-capped per org — unlimited cohorts, predictive audiences and advanced behavioural analysis sit on Growth or Enterprise.
Source: Amplitude pricing page ↗✕Plus is restricted to 2 years of data retention; querying older history requires Growth or Enterprise, which are sales-led custom quotes.
Source: Amplitude pricing page ↗✕Audiences (formerly Recommend) is its own paid product — real-time syncs, predictive audiences and downstream activation sit behind a separate Order Form line.

Retention is a Postgres window function run nightly into a materialised view; cohorts are a saved SQL filter your PMs edit in Metabase. Five years of history is a TimescaleDB hypertable, not a contract renegotiation. Predictive scoring is a dbt model in your repo.
