It started with a simple insight.
Five years. Three million users. One stubborn belief — that small businesses in India deserve the same tools the big ones get. Here's how it actually unfolded.
In India, I watched people buy their first smartphones just to use WhatsApp.
— Sujeet Kumar Mehta, Founder
A spark in the gap.
"WhatsApp was at the center of everything. There just wasn't infrastructure built around it."
I've always been captivated by the power of mobile phones — how they've quietly become the pulse of our daily lives. And at the heart of that experience, for so many of us, is WhatsApp.
It's where we stay in touch with family. Where we run our businesses. Where India does its business. I saw firsthand how many people bought their first smartphone just for one reason — to be on WhatsApp.
But despite its central role in our lives, something was missing. WhatsApp didn't yet offer the APIs, the tools, the additional functionalities that real users needed. The platform held enormous potential — and there was a clear gap between what people wanted and what was possible.
That gap was the spark.
I knew I had to build something to bridge it. So I started working on an app that would do everything users wished WhatsApp could do — saving statuses, chatting with unsaved numbers, managing two accounts on one phone, and most importantly, helping businesses send bulk messages to their customer lists.
Five years of building.
Almost every day.
From the moment the idea took root, I threw myself into it. Day after day. For more than five years now.
This journey has been a labor of love — countless nights of coding, multiple full redesigns, relentless problem-solving. The obstacles were many. There were moments when it felt like the world was actively trying to pull us down.
But each time, we got up stronger. More determined. More clear about what we were building and why.
And the journey has been worth it.
More than 6,000 businesses have trusted us enough to upgrade to paid plans — across nearly every country in the world. Our growth during the COVID-19 pandemic was a particular testament to the dedication, as I worked tirelessly to address even the smallest issues and make sure every user felt supported.
Then in mid-2021, something incredible happened.
"The growth wasn't luck. It was thousands of hours of refusing to give up on small things."
WhatsApp launched its official Business API.
Suddenly, the potential felt limitless.
Bangalore. A team.
A new beginning.
"We weren't just building an app anymore. We were crafting a solution."
To take this opportunity seriously, I needed a real team — engineers who could build with the official Business API, designers who cared about craft, people who would commit to the long road. So I made a bold move and relocated to Bangalore.
Ashish and Mayank, two brilliant minds, came with me. Together, we began breathing life into a new vision.
We weren't just building an app anymore — we were crafting a solution.
Vivek, a top UI/UX designer whose work had been recognized as one of Apple's top 10 designs of the year, brought his genius to our project as a consultant. With his guidance and the unwavering full-time dedication of Madhushree, our UI/UX designer, we shaped the design language of the new product.
While we were heads-down on product and design, the line to real customers still had to stay human — onboarding that didn't feel like a ticket queue, support that didn't sound like a script, retention when someone was about to quietly churn. Through that stretch, Anjali — who had been with us since 2014 — stayed in the trenches with us. For well over two years, she carried support, onboarding, retention, and when the moment called for it, sales — often all in the same week. I don't think we could have survived that phase of the journey without her; she made the company feel dependable long before the product looked finished.
After months of focused building, we launched our first version of WhatsTool Business — right after Diwali 2022.
The team taking shape.
Two clients who changed everything.
Our first two major clients — Kapila and CleanFanatics — weren't just customers. They became partners.
Their constant feedback, their willingness to call out what wasn't working, their belief in what we were building — that's what shaped WhatsTool into what it is today. Every awkward edge they pointed out got smoothed. Every gap they highlighted got filled.
My friend Chandan, with over a decade of experience in app development, and Animesh, our backend engineer, played crucial roles in guiding the tech team to craft a product our customers actually fell in love with.
As WhatsTool found its footing, the team grew with it. From 8 people to 15 — bringing in passionate folks for marketing, sales, and support. Prashant joined to lead marketing with a sharp expert hand. Komal and Shashikiran stepped up to handle customer success.
By Diwali 2023, we launched a small-business-focused package. The response was overwhelming.
"They weren't customers. They were partners — they shaped the product as much as we did."
Today. And what comes next.
"We're not stopping here. We're aiming higher."
We've now served over 6,000 paying customers, helping them leverage the power of WhatsApp Business API for marketing, support, and automation that actually drives growth.
But we're not stopping here.
Our mission is bold and clear — to reach 1 million businesses. To become the most trusted and preferred solution in the WhatsApp marketing and automation space. To help businesses grow with clear messaging, real outcomes, and promises that get kept.
Every week, I keep pouring my heart into WhatsTool, knowing that building something meaningful takes time. The path hasn't always been easy — and there are weekends when I find myself asking, "Why am I still doing this?"
But then I remember. The lives we've touched. The businesses we've empowered. The dream that started it all on a regular Indian afternoon, watching someone buy their first smartphone just to use WhatsApp.
And so, I keep going.
Driven by the belief that WhatsTool is more than just an app. It's a movement — to help businesses thrive, reach their audiences with trust and integrity, and grow in ways they never imagined.
The milestones.
The journey, condensed into the moments that mattered most.
Help every Indian business grow on WhatsApp — with clarity, trust, and real outcomes.
To reach 1 million businesses and become the most trusted name in WhatsApp marketing & automation.
What keeps me going.
Three things I come back to whenever the doubt creeps in.
The lives we've touched
Every business owner who tells us WhatsTool changed how they reach customers — that's the real metric. Not installs. Not revenue. Lives.
The team we've built
People who could be anywhere, who chose this. That trust is something I never take for granted — and never want to let down.
The dream that started it
That moment of seeing someone buy their first smartphone just for WhatsApp. The gap I once saw is still there. The work isn't done.
We're just
getting started.
If this story resonates, there are two ways to be part of what comes next.
