Verification Report
Source review, claim checks, benchmark tracking, and calculator validation for the AI GTM handbook.
Written and reviewed by Eric Han · Co-founder & CTO, reopt
October 23, 2026 primary-source review
Compared Google Search Central's AI features guidance, HubSpot Credits and billing (updated October 20), and prospecting-agent documentation. Distinguished billing defaults from current settings, product usage from business outcomes, and observed citations from causal lift. The incremental calculation is illustrative, not a customer experiment result.
Validation covers MDX, internal links, and example structure. No CRM settings were changed, credits spent, outreach sent, or campaigns run. Earlier market figures and review dates below describe historical sources.

Deliberately Not Claimed
- AI agents fully replace SDRs, AEs, or CSMs.
- Vendor-reported performance numbers will reproduce in every company.
