Hey Product Hunt 👋 I'm Dennis, and I built InFilly out of real frustration — and a healthy dose of fear. I run a marketing agency focused on B2B and industrial clients. I'm active on LinkedIn every day — posting content, building an audience. But here's something I've learned the hard way, both from my own experience and from dozens of conversations with clients and peers: The people with 10,000+ followers who say "LinkedIn doesn't bring clients" — they're not wrong. They're just not sending messages. The difference between people who generate revenue on LinkedIn and those who don't isn't follower count. It's whether they consistently send proven, personalized messages. That's where the deals happen — in the DMs, not the feed. Over the past few years, I've personally generated well over six figures in revenue through LinkedIn outreach — for my own business and for the clients we coach. Not through automation. Through real, personal messages at scale. And every single day, the same routine drove me crazy: open a conversation, type a message, copy the person's name from their profile, paste it in, go back for the company name, paste that too. 20, 30, sometimes 50 times a day. And inevitably, I'd send "Hi Sarah" to someone named Lisa. Deal gone. So I looked at the tools out there. The big outreach platforms cost $25–30/month and came with a full CRM suite — which most of my clients didn't use and didn't need. Paying that much for a simple autofill felt absurd. And then there were the automation tools. I've personally watched people in my network get their LinkedIn accounts suspended for using them. People who'd spent years building their presence, their connections, their reputation — gone overnight. My own LinkedIn profile is one of the most important assets I have for client acquisition. There's no way I'm putting that at risk. So I decided to build exactly what I needed: a tool that fills in names and companies with one click, but doesn't automate anything. No auto-sending. No mass messaging. No API calls to LinkedIn. You always click "Send" yourself. That's InFilly. A Chrome extension that sits right inside your LinkedIn message window, reads the recipient's profile data, and fills your templates instantly. Everything stays in your browser — no data leaves, no servers involved. It's free to start (1 template, first-name autofill). Pro is $3/month for up to 50 templates, full autofill, and outreach tracking. I priced it so that saying no would feel like leaving money on the table — because the time it saves you every month is worth many times more. I'd love to hear from you: What's the most annoying part of your LinkedIn outreach workflow? — Dennis
