LinkedIn DMs for social proof collection
Use LinkedIn direct messages instead of cold email when requesting testimonials or product feedback, leveraging profile credibility for 2.5x higher response rates.
Why this can grow a startup
When you ask for a favor (testimonial, feedback, or case study participation), prospects need to know you are a real person. LinkedIn's built-in credibility signals — photo, work history, mutual connections — instantly lower the prospect's guard in ways a cold email address never can. The 2.5x improvement in response rate means founders can build a social proof library dramatically faster, which compounds conversion improvements across every other channel.
Company example
Wovly analysis of 251 founder case studies (March 2026) — an indie hacker switched from personalized cold emails (19% response rate) to LinkedIn DMs targeting the same user profile and achieved a 50% response rate for testimonial requests.

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.
