Show HN: LeadSynth – Capture leads at the exact moment they're looking

https://www.leadsynthai.app/
2•datamine007•1h ago
Hi HN,

I’m a founder building LeadSynth after running into the same problem over and over:

Our product was fine. Our messaging was fine. But lead gen felt random and exhausting.

What we realized was that most lead gen fails because of timing, not quality.

When someone posts: “Looking for a tool that does X” “Any recommendations for Y?”

They’re in a short decision window (often hours). If you reply early with something useful, you’re in. If you reply later, you’re usually out — regardless of how good your product is.

As founders, this is hard to capture manually. These signals happen: - across time zones - outside business hours - while you’re coding, sleeping, or offline

So we built LeadSynth to solve that exact problem.

What LeadSynth does: - Monitors public conversations (Reddit, X, LinkedIn) 24/7 - Detects explicit buying intent (not keyword noise) - Drafts and posts contextual, helpful replies automatically - Starts real conversations while founders focus on building

This isn’t cold outreach. We only engage when someone explicitly asks for help.

Why founders use it: - No scraping or email blasting - Much higher response rates than cold outreach - Consistent inbound-like conversations without ads - Lead gen runs while you build instead of replacing your day job

We’re using LeadSynth to grow LeadSynth, which is how we validated it. The biggest unlock wasn’t more leads — it was never missing the right moment.

Happy to answer questions, including: - How we avoid spammy behavior - How we detect intent vs casual mentions - Platform safety and rate limits - What breaks at scale

One thing we learned quickly: speed matters more than perfect copy.

The first helpful response often wins simply because the buyer is still deciding. Later replies aren’t bad they’re just late.

That insight changed how we think about distribution entirely.
