LinkedIn DMs for social proof harvesting
Use LinkedIn messages instead of cold email when collecting testimonials and feedback, achieving 2.5x higher response rates.
Why this can grow a startup
When asking for a favor like a testimonial or product feedback, prospects need to know you are a real person. LinkedIn's built-in credibility — profile photo, work history, mutual connections — instantly lowers the recipient's guard in a way a cold email address never can. The 2.5x improvement in response rate means you collect social proof faster, which accelerates landing page conversion and trust-building with new prospects.

When to use it
Use this when LinkedIn is relevant to 0-100, 100-1K and you can run a bounded test with a free budget.
When not to use it
Do not use it as a substitute for customer evidence, a clear owner, or a measurable stop condition. Local platform rules and market behavior still need checking.
Founder checklist
- Read wovly.ai and identify what is directly supported.
- Choose one channel context: LinkedIn.
- Define the test around 2.5x higher.
- Set an owner, evidence window, and stop condition before launch.
