WHITE PAPER - MAY 2025
WHY VCs SHOULD RETHINK THEIR APPROACH TO MARKETING?
Marketing is not a luxury; it does not equate advertising;
it is not SMM or "brand"

Marketing IS the growth engine.

In a recent white paper, we partnered with NOTWICS to survey 183 VCs and uncovered a key growth bottleneck:

🔸 69% say poor marketing has prevented companies from scaling
🔸 62% rely on retention metrics, but 38% say startups underperform there
🔸 Yet only 23% work with marketing experts at all

We believe that marketing should be treated as a growth engine, not an afterthought.

By integrating growth marketing expertise from due diligence to post-round scaling, VCs can unlock smarter spending, faster traction, and more confident investment decisions.
