SETTING A GLOBAL STANDARD

    Never again
    NDA ping-pong.

    NDAs are necessary – weeks of legal back-and-forth are not. Harpo replaces them with one drafted, globally acceptable standard — reviewed once, signed in a minute, archived for life.

    Chapter 01 — The problem

    Nobody likes NDAs - still everyone needs them

    Three numbers explain why every commercial team eventually starts dreading the words "let's get an NDA in place."

    30%

    of legal capacity, lost.

    NDAs easily consume up to a third of in-house legal bandwidth. Hours redlining boilerplate are hours not spent on the deals that matter.

    €0

    of revenue generated.

    NDAs are revenue-neutral by definition. The endless ping-pong, however, is anything but free.

    of repetitive review.

    The same standard clauses, negotiated again and again — over wording changes that make no real difference.

    Chapter 02 — The proposition

    Imagine every NDA handled in a single click — same protection, globally accepted template, no redlining, no review, no delay.

    That is Harpo. A quiet instrument that returns your legal team's time, and your deal flow's momentum.

    The template

    One document. Every deal.
