Growth idea action plan
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.
Ian's take
From scaling consumer platforms across MENA and Southeast Asia, my default is to distrust growth work that only looks good in a slide. Founder-led distribution works when it is proof-led. I would not post theory for this. I would show what changed, what surprised me, what I would do again, and what an operator should try next. I would run it small enough to learn quickly, then only scale the parts that real users repeat, save, reply to, or buy from. For this tactic, I would watch 2.5x higher before putting more time or budget behind it.
Action plan
- Define one narrow startup segment where linkedin dm for social proof collection can create a measurable lift.
- Turn the tactic into one offer, page, campaign, or workflow for the LinkedIn channel.
- Use the evidence from wovly.ai to set the first version of the message, format, and audience.
- Launch a small test for 7 to 14 days with one success metric: 2.5x higher.
- Review the result, keep the winning message, remove weak variants, and turn the learning into a repeatable growth playbook.
