Venture Harbour: multi-step forms up to 300% better than single-page — correctly attributed (NOT CXL/ConversionXL)

Claim: "Multi-step lead forms can convert up to 300% better than single-page forms." — Venture Harbour (Marcus Taylor), updated April 4, 2026.

Source: https://ventureharbour.com/multi-step-lead-forms-get-300-conversions/

Confidence: Verified (Venture Harbour's own portfolio testing).

Important correction: This 300% figure is widely misattributed across vendor blogs to "ConversionXL" or "CXL" research. The correct primary attribution is Venture Harbour's own portfolio testing. If a piece of Candid writing cites the 300% figure, attribute it to Venture Harbour, not CXL.

This is another instance of RULE: Every non-trivial claim carries a named source with author/institution + date + URL. Confidence flag honest. — the discipline of finding the original source catches the recycled mis-attribution. See Mediafly Feb 2022: 13 min vs 8.5 min engagement on interactive vs static — but the measurement was B2B sales decks, not marketing websites for the canonical "stat that travels far from its source" example from brief 2.
