They Seemed Perfect... Until They Weren't

In the startup world, time and trust are your most valuable assets. But bad partnerships—whether with a consultant, investor, vendor, or advisor—can derail your progress and drain your resources.

Here’s the reality:

  • A glowing LinkedIn profile doesn’t guarantee results.
  • A polished pitch can hide red flags.
  • Even referrals sometimes lead to disappointment.


Three months later, you’re left cleaning up the mess:

  • Missed deadlines.
  • Promises that weren’t delivered.
  • Valuable time and money, wasted.


Your time is too valuable to gamble. Use DNWW to protect it.
