The buyers are in the comments.
Under every review, tutorial, and comparison in your space, viewers are asking what to buy and what to avoid. LeadSynth reads those comments, finds the buying intent, and reaches out in your voice while the thread is still live.
01 — Why the comments are full of buyers
A backlog of demand that never expires.
Watching a product review or a how-to is already high-intent behavior — the viewer is researching a purchase. The comments go further: “does anything do this but cheaper?” “this didn't work for my use case, alternatives?”
These comments sit on evergreen videos, so the intent keeps arriving long after upload. A two-year-old comparison can surface fresh buyers every week. The catch: nobody reads every comment on every relevant video. LeadSynth does, and it answers the ones that matter.

How LeadSynth works on YouTube
Tell LeadSynth your ideal customer and the kinds of videos they watch. It monitors those comment sections and scores each comment for genuine buying intent.
When one clears the bar, it drafts a contextual reply or message specific to what the viewer asked — in your voice, never a template — and reaches out at human pace, dropping your calendar link when they are ready.
The result is outreach that answers a real question — and a 20.6% reply rate across channels versus the 1-3% typical of cold email.
“great review but the one you featured is way out of my budget. is there anything that does the same thing for a small team without the enterprise price tag?”

03 — The proof
Reply rate on YouTube · from an evergreen backlog
Cold email sits near 1%. On YouTube we answer a question a researching buyer left on a video — and that backlog keeps refilling itself.
Measured across 686 accounts over the last 90 days. Every message replies to a real, in-the-moment buying signal — which is why the number holds.
FAQ
Asked & answered.
How does LeadSynth find leads in YouTube comments?
LeadSynth monitors comment sections on relevant videos — reviews, tutorials, and comparisons in your space — for buying intent. When a viewer asks 'is there a tool that does X?', complains a featured product fell short, or asks for an alternative, LeadSynth scores the comment and surfaces it, then reaches out in your voice while the thread is active.
Which videos does LeadSynth watch for comments?
You set the targeting by topic and channel type. LeadSynth focuses on the videos where your buyers gather — product reviews, how-to tutorials, and competitor comparisons — because those comment sections are dense with people actively evaluating a purchase. You can add or remove targets at any time.
Does it reply on the comment, or reach out directly?
LeadSynth can post a helpful, contextual reply on the comment to open the conversation, and route warmer signals into direct outreach where the platform allows. Either way the message is specific to what the viewer said, written in your voice, and ends with your calendar link when they are ready.
How is YouTube lead generation different from cold email?
Cold email targets people who never signaled interest. YouTube comments come from viewers actively researching a solution — watching a review or tutorial is high-intent behavior, and a question in the comments is even higher. That is why contextual outreach converts: across 686 accounts LeadSynth reports a 20.6% reply rate, versus the 1-3% typical of cold email.
