Most B2B SaaS teams can't answer one question: which ad created this revenue?
Long sales cycles, multi-contact deals, and Stripe revenue break GA4's data model.
Deal amounts are entered by reps. Real cash lives in Stripe. Numbers never tie out.
Ad blockers, ITP, and consent gating quietly strip 15-50% of conversion signal.
Branded search looks like a hero. Brand, content, and podcast spend look like waste.
One platform. From first click to closed-won revenue.
