Onboarding drop-off is killing our trial conversion.

We only find out at the end of the month. Is there a tool that shows the drop-off step by step while it happens?

Why it matches

Actively looking for onboarding drop-off visibility.

Suggested reply
We built Harbor for this: it shows first-hour drop-off per onboarding step, so you can fix the flow that leaks.
Open on Reddit

First replies shape the thread.

Early comments have a fair chance to earn visibility while attention is still forming.

How it works

The searches learn every day. We keep what works.

Buyers are already talking on Reddit. LeadFast finds those conversations early, and the searches get better every day.

  1. 01One URL teaches the system what the product sells and who needs it.
  2. 02Searches that find buyers stay. The ones that stop working get replaced.
  3. 03Every candidate is read before it becomes an alert. Only real matches arrive.

Set it up once.
Stay in control.

Your website tells AI what your product solves. Confirm what we understood, then let monitoring run.

  1. Enter your website

    We understand your product and the problems it solves.

  2. Confirm your product

    Correct anything we missed. AI handles discovery and filtering.

  3. Receive the opportunities

    Relevant posts arrive in Slack, Telegram, email, or a webhook.

What we understood

Reddit monitoring for founders who find buyer conversations too late.

What we’ll look for

People missing relevant Reddit conversations or struggling to find them in time.

Artificial intelligence reads the meaning, context and buyer need before alerting you.

You ship. LeadFast adapts.

Website checked daily. Your searches maintain themselves, no feed to check, and it keeps improving as it learns your buyers.

No need to check another app. We’ll come find you.

Set up your product once. When a relevant Reddit post appears, the alert reaches the tools you already watch. No feed to refresh. No inbox to clear. No new daily habit.

SlackTelegramEmailWebhook

The app is there when you need control. The alert is there when you need to act.

Works with your agent

Your agent wires it up in one click.

MCP for agents, REST for your stack, webhooks for your own pipe. Full setup in the agent guide.

Can I try LeadFast without a credit card?

Yes. Your 14-day trial starts when you create your account. No credit card is required. If you do not choose a plan, monitoring and product access stop when the trial ends.

How quickly are alerts delivered?

Post to alert in under one minute, measured from publication to acceptance by your connected destination. Actual delivery times can vary.

Do I need to keep checking the app?

No. We review your website daily and update monitoring when your product changes. Matching posts reach Slack, Telegram, email, or your webhook. We email you only the changes that affect monitoring. You can correct what we understand about your product at any time.

What does the product monitor?

Newly published public Reddit posts. It does not monitor comments, private communities, messages, or DMs.

Does it respond on Reddit for me?

No. Every delivered match includes a short Suggested Reply you can use, edit, or ignore, but LeadFast never posts, comments, messages, votes, follows, or contacts anyone.

Do I need to connect my Reddit account?

No. Keep your Reddit account yours. LeadFast watches publicly available Reddit posts. No Reddit login, username, or account access required. When the right post appears, we send it to you. You decide whether to respond.

Do I have to babysit keywords?

No. There are no keyword lists to maintain. LeadFast builds the searches from your website, checks it daily, and updates monitoring when your product changes. Your own edits are preserved. The full loop is in how it works.

What happens when I change my product?

Monitoring follows. New positioning, a new feature, or a new audience changes what we look for on the next website review. You only get emailed when a change affects monitoring.

Does it get better over time?

Monitoring keeps its searches aligned with your product and reviews how each search performs. The Dashboard shows posts analyzed and matches delivered over the last 30 days. The daily review behind it is in how it works.

The next relevant post will happen with or without you.

The only question is whether you find it while the conversation is still open.
