THE AI GTM INDEX·Snapshot 2026-05-05

The AI GTM Index — 67 tools, what they replace, what's real

The AI-native GTM startup class — Clay, Profound, Granola, Rox, Inflection.io, 11x, and 61 more — mapped to the legacy tools each one replaces. Funding, ARR, status badges (live, acquired, stalled, pre-launch), and caution flags on every row. The buyer's view of who's real and what they cost to swap.
