Hey PH community!

I'm Dev, a solo maker and I just launched CommentIQ today.

Ask any AI chatbot "why is my user retention dropping?" and you'll get a decent list of suggestions. Organized, readable, and almost entirely useless for hard problems.

Why? Because complex problems don't yield to a single perspective. Charlie Munger spent a lifetime proving this. His answer the one that helped build Berkshire Hathaway into one of the greatest investment machines in history was the Latticework of Mental Models: a cross-disciplinary framework that forces you to triangulate truth through multiple lenses before reaching a conclusion.

FunBlocks AIFlow brings this philosophy into an AI-powered thinking tool. It doesn't just answer your question. It thinks about your question the way Munger would.

What Is Munger's Latticework of Mental Models?

Have you also noticed that LinkedIn posts all have the same voice now?

If you scroll the app for 2 minutes, a big part of your feed will be filled with posts that have:

• Short sentences.

• One-liners.

• "Not X. Not Y. But Z."

I built PDF Redactor Pro a Windows desktop tool that permanently removes sensitive information from PDF files before sharing.

It auto-detects emails, phone numbers, SSNs, credit cards, and more. Supports keyword search, RegEx patterns, image and table redaction, batch processing all 100% offline. Your documents never leave your PC.

Right now it's free, or pay what you want

The old way of selling online is broken. You design a product, order hundreds of units, pay for inventory, rent warehouse space, run ads and then hope people buy.

Most don't. 82% of small businesses fail because of cash flow problems.

What if you could flip that entire process? What if customers committed their money first, and you only produced what was already sold?

So I made an iOS app which opens web versions of social media in tabs like style. It's free to use without any ads. Would you like to try and give feedback: https://apps.apple.com/us/app/so...

In 2011, my team s technology was acquired by Google for a specific purpose: solving the performance scaling problem for a fragmented Android hardware ecosystem.

Today, the Web is facing that exact same "Fragmentation Tax."

Because 63 million Indian SMEs deserve better than Excel sheets Hey Product Hunt I want to be upfront this isn't a polished startup story. It's a messy one. And I think that's why it might resonate. --- A year ago I visited a friend who runs a clothing store in Surat. He was doing well genuinely well. Good products, loyal customers, decent revenue. But when I sat with him for a day, I watched him do something that stuck with me. Every 10 minutes he picked up his phone and manually replied to WhatsApp messages. Product questions. Price inquiries. Order follow-ups. Complaints. From 9AM to 11PM. I asked him "Do you have any system for this?" He looked at me and said: "Bhai, yahi system hai."
(Translation: "Brother, this IS the system.") --- That line is why WakFlow exists. --- We're not solving a problem we read about in a research paper. We genuinely spent months sitting with business owners real estate brokers in Jaipur, clinic owners in Pune, D2C founders in Delhi and asking them one question: "Walk me through your actual day." What we found wasn't a technology problem.
It was a tools problem. The tools that exist were built for someone else.
Wrong language. Wrong payment system. Wrong assumptions about how businesses here actually operate. --- So we built three things: A CRM that treats WhatsApp as the primary channel not an afterthought. Leads flow in automatically, follow-ups happen without reminders, and nothing slips through. A shared inbox so entire teams can work from one WhatsApp number without passing a phone around. Sounds basic. Wasn't available in a way that worked for this market. An AI agent that handles sales conversations, sends product photos, and processes payments even when the owner is asleep. --- What surprised us most wasn't the product. It was the reaction when we showed the first version to that friend in Surat. He watched the AI bot take an order at midnight, confirm it, and send a payment link all automatically. He just kept saying "yaar..." over and over. He didn't say it was impressive. He said: "This is the first time I feel like I can actually take a day off." That was the moment we knew we were building the right thing. --- 8 months later: 500+ businesses are using WakFlow across India.
We've never run a single ad.
Every customer came from another customer. --- I'm sharing this today not because I think we've figured everything out we absolutely haven't. But because Product Hunt has always been the place where builders share things they genuinely care about. And I genuinely care about this. If you've ever built something for a market that mainstream tech ignores you'll understand why this matters to us. Happy to answer any questions about what we built, why we made certain decisions, or what surprised us along the way. And if you know someone running a business on WhatsApp and Excel send them to wakflow.com. They'll thank you. [Kanishq], WakFlow
