You don't need to spend $500K/mo on ads to deserve knowing why your CPA doubled.
Northbeam gives you the most accurate attribution numbers in the market. Full stop. If you're spending $250K+/mo across Meta and Google, and your primary question is 'which channel deserves credit?' — Northbeam is excellent. But here's the gap: Northbeam tells you a campaign's ROAS. It doesn't tell you WHY that ROAS changed. It doesn't decompose performance into root causes — CPM pressure vs. creative fatigue vs. audience saturation vs. budget pacing issues. And at $1,000–$5,000+/mo with annual contracts, it's out of reach for most media buyers. Sentrum is the diagnostic dashboard for Meta buyers. Built by a media buyer with 8 years of experience, it goes deep on the question Northbeam doesn't answer: why did performance change, and what should I do about it? No annual contracts. No $250K/mo spend floor.
Enterprise-grade multi-touch attribution with customizable models, Media Mix Modeling+, and Northbeam Apex for feeding first-party data back into ad platforms. Three tiers based on monthly spend: Starter (<$250K/mo), Professional (>$250K/mo, annual contracts), Enterprise (>$500K/mo, custom). Reportedly $1,000–$5,000+/mo.
Brands spending $250K+/mo across multiple channels who need the most accurate cross-channel attribution available
Northbeam gives you more accurate numbers. Sentrum tells you what those numbers mean. "Your CPA increased 22% because ad set X hit frequency 3.1 and creative Z's CTR has declined 0.08% daily for 5 days" — that's diagnosis. No attribution tool provides this, regardless of accuracy.
Northbeam's Professional tier requires $250K+/mo spend and annual contracts. Their Enterprise tier starts at $500K+/mo. Sentrum is built for every Meta buyer — from solo operators to agencies to in-house teams — without requiring enterprise-grade ad spend to justify the cost.
Northbeam says "here are your numbers." Sentrum says "here's what to do." Refresh these 3 creatives. Reallocate budget from ad set A to ad set B. Your scaling headroom is X%. Recommendations tied to diagnosed causes, not generic best practices.
Northbeam spreads across every channel. Sentrum goes deep on Meta — Advantage+, CBO/ABO dynamics, creative fatigue, frequency × placement interactions, CPM auction pressure. Purpose-built for the platform's specific mechanics.
Users report Northbeam requires significant implementation effort and annual contracts on Professional/Enterprise tiers. Sentrum connects to your Meta account and starts delivering diagnostic insights immediately. No pixel deployment, no annual commitment.
