Mixpanel
Mixpanel is a product analytics SaaS from Mixpanel Inc. (San Francisco; founded 2009 by Suhail Doshi and Tim Trefren; CEO Jen Taylor since September 2025). Since February 2025 it prices strictly by event volume: Free tier caps at 1M events/month; Growth plan gives the first 1M free then charges $0.28 per 1,000 events (~$2,520/mo at 10M events, ~$5,320/mo at 20M); Enterprise is custom, with MTU-based plans starting near $20,000/year. Two commonly-missed surcharges stack on top of overage billing: Group Analytics (B2B account-level rollups) adds a 40% premium, Data Pipelines (warehouse export) adds 20% — pushing a 10M-event Growth account with both add-ons to roughly $4,000–4,500/month. Mixpanel reports 29,000+ customers, after raising $277M total including a $200M Series C at a $1B valuation (Nov 2021). Current version/status: Event-based pricing model, effective Feb 2025 (SaaS, continuously updated — no versioned releases). License: proprietary SaaS. Pricing: Free tier caps at 1M events/month; Growth plan is $0.28 per 1,000 events after the first 1M free (~$2,520/mo at 10M events, ~$5,320/mo at 20M); Group Analytics adds a 40% surcharge and Data Pipelines a 20% surcharge on overage; Enterprise is custom, with MTU-based plans starting around $20,000/year. Maintained by Mixpanel Inc. (San Francisco; CEO Jen Taylor since Sep 2025, succeeding Amir Movafaghi).
Pick Mixpanel when you need cohort/retention analysis plus B2B account-level rollups (Group Analytics) without hand-rolling SQL warehouse joins — the event-based pricing is at least transparent math, unlike Amplitude's opaque MTU-credit system. Skip it if you're pre-revenue with unpredictable event volume: PostHog's self-hosted free tier won't blindside you the way Mixpanel's overage math will once instrumentation sprawl pushes you past 1M events, especially with the 40% Group Analytics or 20% Data Pipelines surcharges stacked on top. Mixpanel's own docs effectively concede the real risk: cost tracks event *count*, not event value, so a bloated tracking plan quietly becomes your biggest line item. Known weakness: Mixpanel's own pricing model concedes the core risk in its structure: cost scales with raw event count, so uncontrolled tracking-plan sprawl (duplicate or low-value events) becomes the single biggest driver of an unexpectedly large bill, independent of how much analytical value those events actually provide.
