We didn't set out to build a product.
We just needed to fix a problem.
We both run ads. Every single day. David is a PPC specialist who managed over $750K in ad spend in 2025 alone, and he built CommentR from the ground up. Kevin runs Allin Agency, handling branding, video production, landing pages, and client campaigns. We know what it takes to turn clicks into customers.
But here's what we kept seeing: great ads driving traffic, people commenting with real buying intent, "What sizes do you have?", "Do you ship to my country?", and nobody replying. Not because brands didn't care, but because they simply couldn't keep up. Hiring someone just for comments? Too expensive. Doing it manually? Not scalable. Ignoring it? Burning money.
So we built CommentR. A system that drafts replies, learns your Brand Voice, self-improves as you use it, and never posts without human approval. It's the tool we wished we had for our own clients. Built for small and mid-size businesses who can't afford a dedicated community manager, but designed to scale for enterprises who want to save hours every week.
Meet the founders
Two young dads. Two ad professionals. One shared frustration that turned into a product.
David
Co-Founder · Development & PPC
David has been deep in PPC & Digital Marketing, in 2025 alone he managed over $750K in ad spend across dozens of client accounts. He saw the same thing over and over: perfectly optimized campaigns driving traffic, comments flooding in with buying intent, and nobody was there to answer them.
So he built CommentR's system. The API integrations, the AI pipeline, the comment syncing engine, that's all him. He's the reason CommentR actually works under the hood. When he's not coding or optimizing campaigns, he's chasing his little boy around the house.
Kevin
Co-Founder · Branding & Creative
Runs Allin Agency, a marketing and content creation agency where he handles everything from brand strategy to video production to client campaigns. When AI started reshaping the industry, he knew he had to be part of it, not just use the tools, but build one that solves a real problem he deals with every single day.
Every page you're looking at, every animation, every landing page, every sales video for CommentR, that's Kevin. He's the reason the product doesn't just work, but feels right. Also a dad to a little boy, which means his free time is exactly zero, another reason he wanted to build something that handles comment replies for him.
