VERDICT

Should I use Lifesight?

Agentic unified marketing measurement: MMM, attribution, CDP, and identity in one platform - lifesight.io

Depends. Worth a serious evaluation for funded DTC or e-commerce brands with real ad spend and data analysts who want unified measurement. Small teams or anyone wanting transparent, self-serve pricing should look elsewhere.

Confidence

Medium. Based on ~14 usable public sources. Caution: many 'LifeSight' sources in research describe WTW's pension master trust, a completely different company.

Gotchas - check before you buy

medium

Quote-based pricing; expect negotiation. Guess: cost likely scales with ad spend or data volume.

As a registered data broker, consumer opt-out requests must be honored — loop in privacy counsel.

Case studies are vendor-published; validate claims with a paid pilot first.
