Building LeadSynth AI: From Crickets to Conversations
When I first started launching products, the pattern was always the same:
Build → Post → Wait → …crickets.
The hardest part wasn’t building. It was finding people who actually needed what I had built.
That’s why I started building LeadSynth AI. Instead of static databases or scraping cold emails, LeadSynth listens to the internet in real time: Reddit, X, forums and surfaces conversations where people are already describing the exact problems your product solves.
No guessing. No shouting into the void. Just showing up at the right time, in the right place.
Since launching, I’ve been amazed at how quickly founders jumped on this idea:
✅ 110+ founders signed up so far
✅ Thousands of conversations surfaced
✅ Feedback that it saves hours of hunting for leads
Right now, I’m doubling down on two things:
Onboarding & integrations (HubSpot, Pipedrive, etc.) to make it seamless
AI outbound agents that don’t just find leads but also start conversations for you
The goal? To make “finding your first 1000 users” less of a guessing game and more of a repeatable system.
It still feels early, but the momentum is real and I’d love to hear from other Indie
Hackers:
👉 What’s been your biggest pain point in finding customers?
If you’re curious, here’s the product: https://leadsynthai.vercel.app
Awesome, that's exactly what I need. I'm just starting to build a new SaaS and have just set up a waitlist and try to get traffic to it to validate the idea. So yeah, curious how effective it will be. The idea is great.
So during trial only reddit can be used? So for X I need to immediately upgrade, right? But if it's working the price is more than fair I guess.
Yeah exactly and even with the upgrade you can target way more communities on Reddit rather than just 5 with free mode.
If possible, I can try to become your product promotion manager in China.If you're interested, please email me at
This really resonates. When I was building ScrumBuddy, I hit the same wall. The building was the easy part, but getting in front of the right people at the right time felt like throwing code into the void. What finally worked was shifting from “more output” to “better orchestration,” making sure context and timing flowed cleanly from idea → backlog → UI → backend → PR.
LeadSynth feels like that same orchestration applied to growth. Instead of chasing cold lists, you’re wiring yourself directly into the live pulse of where problems are being voiced. That’s a much cleaner signal, and a far stronger place to start conversations.
With the AI outbound agents, how are you thinking about keeping that balance between automation and authenticity? In ScrumBuddy, I’ve found the human-in-the-loop moments are what keep trust intact, even when the heavy lifting is automated.
