Cycle 1 — what works in B2B PR pitches (preliminary findings)
Data accumulating
PRAPI Research Cycle 1 tests three pre-registered hypotheses about pitch framing: external deadline + concrete data point (H1), founder voice (H3), and operational insider data (H5). This page accumulates data toward the 200-pitch-per-arm significance threshold; verdicts appear once the cycle closes.
