As answered by people managing LeadGenRunner and Cert Decoder.
LeadGenRunner's answer
LeadGenRunner was born out of frustration. I was spending 3-4 hours every day scrolling through dozens of Telegram groups looking for potential clients - people asking for recommendations, looking for services, discussing problems I could solve. The messages were there, but finding them was like looking for a needle in a haystack. I built a simple keyword monitor for myself, then added AI classification when I realized that even with keyword matches, 70% of messages were noise. The AI layer changed everything - suddenly I was only seeing high-intent leads. I turned it into a product in 2025, and now it saves users hours every day while finding leads they would have otherwise missed.
Cert Decoder's answer:
I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.
LeadGenRunner's answer
LeadGenRunner is a web-based SaaS application built with Python (FastAPI) on the backend and Vue.js on the frontend. It uses the official Telegram API via Pyrogram for real-time message monitoring, OpenAI GPT for AI lead classification and reply generation, and PostgreSQL for data storage. The platform is hosted on cloud infrastructure with real-time WebSocket notifications.
Cert Decoder's answer:
certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server
LeadGenRunner's answer
Digital marketing agencies, B2B sales teams, freelancers, and small business owners who use Telegram as a sales channel. Particularly popular with agencies managing client outreach in Telegram communities, crypto/Web3 projects monitoring industry conversations, real estate professionals tracking buyer inquiries, and consultants looking for project opportunities in niche groups. The common thread: they know their ideal clients are posting in Telegram groups right now, but finding those messages manually is unsustainable.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
LeadGenRunner's answer
Three reasons: (1) It's Telegram-native - built specifically for Telegram's ecosystem using the official API, not scrapers that risk account bans. (2) AI does the heavy lifting - instead of reading hundreds of messages yourself, AI classifies leads by intent and urgency, and drafts ready-to-send replies. (3) Scale without hiring - one person can monitor 500+ chats simultaneously, replacing what used to require a team of 3-5 people manually scrolling through groups. Plans start at $9/month with a free 5-day trial, no credit card required.
Cert Decoder's answer:
Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.

LeadGenRunner's answer
LeadGenRunner is the only tool that combines real-time Telegram group monitoring with AI-powered lead classification. While other tools scrape member lists or require manual searching, LeadGenRunner monitors public messages 24/7 for buyer-intent keywords and uses AI to classify every lead as Hot, Warm, or Cold - so you only focus on prospects ready to buy. It also generates contextual reply suggestions, letting you respond in seconds instead of hours.

Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
