We turned online conversations into customers. Here's how we detect buyer intent at scale.

We turned online conversations into customers. Here's how we detect buyer intent at scale.

The problem: Your ideal customers are asking for solutions right now. You just don't know where.

First 6 months of LeadSynth was brutal.

Product worked. Demos went well. People said "this is exactly what I need."

Then... nothing.

No consistent signups. No predictable pipeline. Just random spikes when I happened to find someone asking for lead gen tools.

The realization that changed everything:

I wasn't losing because the product was bad.

I was losing because I was never there when people were ready to buy.

The buyer intent problem

Every day, hundreds of conversations happen like this:

Reddit, 2:47 AM: "Looking for a tool to automate lead generation. Any recommendations?"

X, 11:23 AM: "Need help finding prospects on LinkedIn. What tools are people using?"

LinkedIn, 6:15 PM: "Our manual outreach is killing us. What automation actually works?"

These people are ready to buy RIGHT NOW.

They're asking their network. Getting recommendations. Making decisions in hours.

If you're not in that conversation within the first 30 minutes, you don't exist.

What I was doing wrong

My "strategy":

• Check Reddit once a day (usually around 10 AM)

• Scroll X when I had time

• Post on LinkedIn weekly

What actually happened:

Someone asked for lead gen tools at 3 AM → Got 8 replies by 8 AM → Picked one by noon

I checked Reddit at 10 AM the next day → Saw the post → Replied 32 hours later

Thread was dead. Decision was made. Deal was lost.

This happened every single day. I just didn't know it.

The shift: From hunting to detecting

Stopped asking: "Where should I find customers?"

Started asking: "How do I detect when buying conversations happen?"

The difference:

Hunting = Active searching

• I manually check platforms

• I search for keywords

• I hope to find something relevant

• I'm limited by when I'm online

Detecting = Passive monitoring

• System watches 24/7

• AI identifies buyer intent

• I get alerted when conversations are live

• Coverage is 24/7 regardless of my schedule

How we built buyer intent detection

Step 1: Monitor where buyers actually talk

Not where we THINK they talk. Where they ACTUALLY talk.

For B2B SaaS:

• Reddit: r/SaaS, r/entrepreneur, r/startups, r/sales

• X: #buildinpublic, #SaaS, founder conversations

• LinkedIn: Startup groups, SaaS communities

Covers ~80% of organic buying conversations.

Step 2: Detect intent, not just keywords

Early mistake: Keyword matching

Searched for "lead generation" → Got:

• "Lead generation is dead" (opinion, not buying)

• "I hate lead generation tools" (complaint, not buying)

• "Just read an article about lead generation" (browsing, not buying)

95% noise. 5% actual buyers.

What actually indicates buying intent:

✅ "Looking for [solution]" ✅ "Need recommendations for [problem]" ✅ "What's the best tool for [use case]" ✅ "Anyone using [category] that works?" ✅ "How do I [problem]" + context of urgency

These phrases = Someone actively shopping, not just discussing.

Step 3: Score urgency and fit

Not all buying intent is equal.

High-intent (respond immediately):

• "Looking for lead gen tool, need it this week"

• "What's the best alternative to [competitor]"

• "Budget approved, need recommendations"

Medium-intent (respond same day):

• "How are people solving [problem]?"

• "Anyone tried [category]?"

Low-intent (skip):

• General complaints

• Theoretical discussions

• No decision timeline

Step 4: Alert in real-time

Get notified within minutes when high-intent conversation appears.

Notification includes:

• Full context of conversation

• Why it's high-intent

• Suggested reply angle

Can respond while conversation is LIVE, not dead.

The results

Before detection system:

• Manually checking: 8 hours/week

• Opportunities found: 10-12/month

• Fresh conversations (<2 hours old): 2/month

• Signups: Random, 3-5/month

After detection system:

• System monitoring: 24/7 automatic

• Opportunities found: 120+/month

• Fresh conversations: 90+/month

• Signups: Consistent, 15-20/month

Same product. Different detection. 4× more customers.

What this looks like in practice

Real example from last week:

Monday, 4:37 AM: Someone posted on r/SaaS: "Looking for lead gen automation that actually works. Tried cold email, response rates terrible."

Monday, 4:42 AM: LeadSynth detected high intent, alerted me

Monday, 7:15 AM: I woke up, saw alert, read context, replied with helpful breakdown of why their cold email wasn't working + mentioned LeadSynth as one solution

Monday, 8:30 AM: They replied asking for demo

Monday, 2:00 PM: Demo call

Tuesday, 10:00 AM: They signed up

Deal closed in 30 hours. All because I was alerted at minute 5, not hour 30.

Why this matters for indie hackers

Most indie hackers are competing against:

• Companies with 24/7 sales teams

• Tools with automated monitoring

• Competitors who reply in minutes

You're checking manually once a day.

You can't win that race.

But you CAN build detection that competes:

• Monitors 24/7 (even when you sleep)

• Detects intent automatically (filters noise)

• Alerts you to high-value conversations only

• Lets you respond fast without grinding 16 hours/day

What we built

LeadSynth = The buyer intent detection system we needed for ourselves

What it does:

• Monitors Reddit, X, LinkedIn 24/7

• Detects buying intent using AI (not just keywords)

• Scores conversations by urgency and fit

• Alerts you when high-intent conversations appear

• Provides context so you can reply in 2 minutes

What changed:

• Stop checking platforms manually

• Stop missing overnight conversations

• Stop arriving 8 hours late to closed deals

• Start responding while buyers are still deciding

For other indie hackers struggling with early customer acquisition

If you're:

• Building something people need but can't find customers consistently

• Spending hours manually searching platforms

• Missing opportunities because you're not online 24/7

• Wondering why competitors are growing faster

The problem isn't your product. It's your detection.

People ARE asking for what you built. You're just not there when they ask.

Question for the community:

How many buying conversations about your product happened this week that you never saw?

If you're checking manually, the answer is probably 80-95% of them.
