How to approach

Framing and angles for outreach

Pitch framing

Lead with a fintech infrastructure or embedded finance wedge, especially where the product solves a concrete financial-system pain point for consumers or businesses.

Personalization hooks

  1. 1Connect to Foursquare-style merchant, mobile, or international partnership experience if relevant.
  2. 2For fintech, frame the problem historically and structurally, not just as a feature opportunity.
  3. 3Mention U.S.-Europe go-to-market if the company has transatlantic expansion plans.
