Saw one Reddit comment… built a full lead scraping SaaS in 3 days and already have 10 people waiting to use it.

Three days ago, I was casually scrolling Reddit when I saw a comment on a post where someone was struggling to get B2B leads, emails, LinkedIn profiles, that kind of stuff. Nothing crazy at first glance, but then I noticed something: a bunch of replies were echoing the same pain point.

People were saying the tools out there are either way too expensive, overly complex, or just unreliable.

So I had this idea, what if I just built a simple, cheap tool to solve this? I already had some components from old projects, so I decided to go full tunnel vision and see what I could build in a weekend.

Fast forward three days, barely slept, probably overdosed on caffeine, but… I’ve got a working MVP live now.

Here’s what it does:
You input your targets, think companies, job titles, industries, and it pulls up verified emails and LinkedIn profiles for them. Super lightweight, no complicated onboarding, and way cheaper than anything else I’ve seen.

And here’s the wild part:
I replied to just one Reddit comment saying “Hey, I’m building something for that if you’re interested,” and I’ve already got 10 people waiting for the link.

I’ll be sharing the public URL next week, just finalizing a few things, but yeah… turns out Reddit is lowkey the best MVP validation tool out there 😅

Moral of the story: sometimes you don’t need to do 2 months of market research. Just listen, build fast, and test in public.
