Hi, I'm Harshil Parikh – Founder of Signal, Chatify, Productica, IsoR-1, SmokeTiles™ & Astro-AI | Tech Builder | Dual-Degree Student (Cybersecurity & Psychology)

I'm a builder at heart who loves solving real-world problems through technology that’s secure, intelligent, and meaningful. I'm currently pursuing a dual degree in B.Tech in Cybersecurity and BA in Psychology, which gives me a unique lens—combining the logic of systems with the depth of human behavior.

Over the last few years, I’ve founded multiple ventures across very different domains—from private messaging and market analysis to culture-tech, sustainable materials, and even AI-driven astrology. Each venture I work on is rooted in a problem I genuinely care about and a solution I’m obsessed with building right.

🔹 Signal – My First Big Leap in Private Communication
I originally founded Signal, the now globally trusted private messaging app known for its commitment to end-to-end encryption and data ethics. The platform was later acquired by the ex-CEO of WhatsApp, and it’s incredibly fulfilling to know it now empowers millions of users worldwide. Signal was where I began proving that privacy can scale.

🔹 Chatify – Secure Messaging, Reimagined
After Signal, I built Chatify—a simpler, more minimal privacy-first messaging platform. It’s built for people like me who care about control, clean design, and distraction-free communication. No algorithms, no ads—just conversations that matter.

🔹 Productica – AI-Powered PMF Co-Pilot for Indian Founders
Productica is one of my most exciting ventures. It helps founders—especially early-stage and student entrepreneurs—understand their Product-Market Fit with AI-generated PASR reports, founder persona mapping, and GTM suggestions. I built it because I personally experienced how hard and confusing it is to validate a new idea in India without any resources.

🔹 IsoR-1 – AI Meets Culture
I’m also passionate about preserving history and heritage in creative ways. IsoR-1 is an AI engine that creates 3D-realistic, surreal images of iconic cultural places like Roopkund Lake, Bhangarh Fort, Easter Island, and more. It’s my way of fusing storytelling, art, and tech into something that can inspire curiosity and cultural appreciation.

🔹 SmokeTiles™ – Turning Waste into Eco Tiles
With SmokeTiles™, I’m working on making the construction industry more sustainable. We’ve developed a formula that turns fly ash, rice husk, and brick powder into strong, eco-friendly tiles. No sand, no waste—just smart, green alternatives for the future of urban development.

🔹 Astro-AI – A New Way to Experience Astrology
Lastly, Astro-AI is my foray into the world of spiritual-tech. It’s not just horoscopes—it’s AI-generated, contextual daily insights across love, career, health, finance, and more. It even lets users ask specific questions about their life. I wanted to create something that blends ancient wisdom with modern personalization, and that’s exactly what Astro-AI does.

Why I Build
I’m obsessed with execution. I don’t just think about ideas—I design, test, ship, iterate, and listen. Whether it’s creating tools for founders, sustainable materials, or storytelling engines, I approach every venture with the same mindset: make something real, make it matter.

“Startups are how I talk to the world. Each one is a message—and a mission.”
