- Signal-driven targeting requires additional tools
What Are the Downsides of Using Fiber AI?
No buying signals
Fiber AI does not include buying signal intelligence. It does not know if a prospect just raised funding, hired a new VP, or started evaluating competitors. Without signals, outreach timing is random rather than strategic. Learn how waterfall enrichment solves this data gap.
Limited enrichment depth
The enrichment capabilities do not match dedicated waterfall enrichment providers. Firmographic depth, technographic data, and multi-source verification are limited. SyncGTM's waterfall enrichment fills these gaps with data from 20+ providers.

For teams that want signal-driven outreach timing and deeper data enrichment, pairing with SyncGTM at $99/mo adds the buying signal layer and waterfall enrichment from 20+ providers that transforms outbound from volume-based to signal-driven.
