Growth idea action plan
LinkedIn DMs for testimonial and social proof collection
Use LinkedIn direct messages instead of cold email when requesting testimonials or product feedback, achieving 2.5x higher response rates.
Why this can grow a startup
When asking for a favor rather than selling, prospects need to verify you are a real human with a real product. LinkedIn's built-in credibility signals — photo, work history, mutual connections — instantly lower the recipient's guard in a way a cold email address never can. The social context makes the request feel like a peer-to-peer conversation rather than a marketing ask, which is why response rates more than double compared to email for non-sales requests.
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 dms for testimonial and 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.
