LinkedIn DM for social proof collection
Use LinkedIn direct messages instead of cold email to request testimonials and feedback, achieving 2.5x higher response rates thanks to built-in identity trust.
Why this can grow a startup
When asking for a favor like a testimonial or feedback, prospects need to see you are a real person. Cold email addresses carry no built-in credibility. LinkedIn's profile photo, work history, mutual connections, and company affiliation instantly lower the recipient's guard. The medium signals that you are a real professional making a genuine request rather than an automated outreach bot. This makes LinkedIn uniquely effective for trust-based asks where social proof matters more than scale.
Company example
Indie hacker experiment documented in Wovly's 250+ case study analysis (March 2026) — personalized cold emails for testimonials hit only 19% response rate, but switching to LinkedIn DMs targeting the same user profiles achieved 50% response rate.

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.
