Best product analytics for agencies

The product analytics market is dominated by 12-15 major players (Amplitude, Mixpanel, Segment, etc.), but almost none are designed for the agency workflow—they're built for in-house product teams. The core pain point isn't the analytics engine itself; it's that agencies need multi-client dashboards, white-label capabilities, simplified permission models, and invoicing that makes sense for reselling analytics to 20+ clients simultaneously. Most agencies either overpay for enterprise features they don't use or cobble together cheap tools and lose data consistency. The real gap: there's no mid-market product analytics platform optimized for agency economics—pricing per client, easy client onboarding, simplified event tracking for non-technical account managers, and dashboards that answer 'did this campaign work?' in 30 seconds instead of 30 minutes of data wrangling. A founder entering this space should focus obsessively on ease of implementation (agencies don't have dedicated data engineers) and on creating templates that work across common campaign types rather than building another flexible-but-complex analytics layer. The secondary opportunity is embedding this as a white-label feature inside agency management platforms like HubSpot or Monday.com, which would bypass the sales problem entirely.
